  • Screening of Maternally Inherited Bacteria in Various Agricultural and
           Livestock Pests

    • Authors: Tayfun KAYA
      Abstract: Pests that pose a risk in terms of agriculture and livestock cause economic losses directly or indirectly. However, some pests are also vectors of various diseases that threaten the health of living things, especially of humans. Therefore, the detection of maternally inherited reproductive manipulator endosymbiotic bacteria is important in the development of alternative strategies to chemical methods in the fight against pests. In this study, the endosymbiotic Arsenophonus, Cardinium, Hamiltonella, Rickettsia, Spiroplasma and Wolbachia in gallery fly (leaf miner fly) (Liriomyza sp.), legume seed beetle (Bruchus sp.), tomato pest Lasioptera sp., cattle louse (Bovicola bovis) and winged red mite (Dermanyssus gallinae) scanning was carried out. As a result of the scans, we could not detect any of the endosymbiotic bacteria studied. This study includes the first known data from Anatolia regarding maternally inherited reproductive manipulator endosymbiotic bacteria in Liriomyza sp., B. pisorum, B. bovis and D. gallinae pests.

  • A Study on Phenol Pollution in the Aksu Creek (Giresun, Turkey)

    • Authors: Selda PALABIYIK; Tamer AKKAN
      Abstract: The phenol and its derivatives are widely available in the environment. The phenol index is considered an important indicator of water purity and quality. Presence of phenols in aquatic environments is also related to petrochemical, agricultural, industrial and municipal wastewater in the environment. It is a variable that should be monitored because it causes bioaccumulation and toxicity in the entire living chain extending to humans, especially the aquatic ecosystem where it pollutes. In this study, it was aimed to define and quantify the total phenol concentration in Aksu Stream according to seasonal periods.For this purpose, phenol concentrations of surface water samples collected from three different points by seasonal sampling from Aksu Stream were investigated. The total phenol concentrations of water samples were reported between 0.069 and 1.125 mg/L. In addition, it was noted that there was no significant difference in phenol accumulation according to the stations (p>0.05), and that the spring with summer and autumn with winter seasons clustered. As a result, it was determined that the phenol pollution in Aksu Stream surface water samples showed an increasing trend compared to the concentrations detected in the past years.

  • Investigation of Some Biochemical Parameters and Mineral Values in the
           Blood of Rainbow trout Growing in Dam and Sea water

    • Authors: Ayşenur KIRAN; Gülay ÇİFTCİ
      Abstract: In this study, it was aimed to investigate the effect of the difference in the breeding environment (pH, temperature, salinity, oxygen content and saturation) of rainbow trout grown in dam and sea water on the level of some minerals (calcium, magnesium, zinc, iron) and biochemical parameters in the serum. The study material consisted of 20 rainbow trout (Oncorhynchus mykiss) weighing about 800-1000 gr in the dam water of Samsun (Derbent Dam) and the Black Sea water (Yakakent). Blood samples were taken from both groups on the same day in December and the pH, temperature, oxygen content and saturation level of the water were determined by YSK oxygen meter, and salinity was determined by refractometry. Total protein (TP), albumin (Alb), cholesterol (TK), glucose (Glu), urea, creatinine (Cre), uric acid (UA), Aspartate transaminase (AST), Alanine Aminotransferase (ALT), triglyceride (TG) Calcium, magnesium, iron and zinc and ALT, AST enzyme activities were determined by spectrophotometric method in an autoanalyzer. It was observed that the salinity, oxygen and saturation levels of the sea water were higher than those of the dam water, and the pH and temperature were close to each other. It was determined that TP, Alb, Alb/Glo, TK, TG, UA and Ca levels in rainbow trout raised in the dam were significantly higher than those raised in the sea (P<0.05). Glu, Cre, Mg and Fe levels were found to be higher in the blood serum of rainbow trout (P<0.05). Zn, urea, AST and ALT levels of rainbow trout raised in sea and dam were similar. In our study where the same fish species were provided with the same feeding conditions, it was observed that the differences in salinity and dissolved oxygen levels of fish farming waters caused changes in some mineral and blood parameter levels in fish. It was concluded that determining the supplementation of the missing minerals in fish according to the salinity and dissolved oxygen level in the environment may be important for the development of the fish.

  • Effect of Different Feeding Materials on the Trace and Nutrient Elements
           of Vermicompost using Eisenia fetida

    • Authors: Turan YÜKSEK
      Abstract: The aim of this study was to determine the influences of different feeding materials on the physico-chemical parameters of vermicompost using Eisenia fetida. In this study, four treatments, with the same conditions in terms of organic wastes type were prepared to produce vermicompost from hazelnut husk (% 100), tea plant waste (%100), hazelnut husk (A) (% 50) + tea plant waste (B) (50%), hazelnut husk (A) (30%) + tea plant waste (30%) + cow dung (20%) + sawdust (15%) + waste newspaper (%5) using earthworms. The standard laboratory analysis methods were used to determine the physical and chemical parameters in the different produced vermicomposts. The mean N content in the growing medium A, B, C, and D was 1,41%, 2,5%, 1,96%, and 1,47% respectively. The mean phosphorus content in the growing medium A, B, C, and D was 807,69 mg/kg, 1748,25 mg/kg, 1491,25 mg/kg, and 1410,75 mg/kg respectively. The mean potassium in the growing medium A, B, C, and D was 11244,69 mg/kg, 7790 mg/kg, 6884,25 mg/kg, and 8006,25 mg/kg respectively. Compared to the initial vermibed mixture, the N, P, and K content was higher in all the growing mediums. The Pb, Cd and As content was lower in all the growing mediums in the final compost than the initial vermibed mixture. Eisenia fetida is very effective in converting some waste materials into high-quality compost and decreasing the heavy metal content in the final vermicompost more than in the initial vermibed mixture.

  • Existence of SARS-CoV-2 (COVID-19) on Aquatic Animals and Aquatic Products

    • Authors: Nihed AJMİ; Muhammed DUMAN
      Abstract: Many pandemic diseases have emerged in the history of the world and these diseases have affected millions of people. Among the marked pandemics in history, the plague, known as the black death, was recorded to cause the death of 17-54% of the world population. As the SARS CoV-2, which emerged in 2019 and belonged to the coronavirus family, caused an epidemic and turned into a pandemic infection, positive cases were detected in more than 342 million people, and more than 5.5 million people died. While this emerging epidemic is still continuing its effects, it has been determined that there are positive cases in pets such as dogs and cats, especially in mink (Neovison vison). Especially in Denmark, Netherlands and Finland, positive animals for COVID-19 were accepted. Unlike the pandemic until today, the COVID-19 has spread to broader geographies and has become an important research topic by affecting many animal species. With the reports that the SARS-CoV-2 - was first transmitted from bats to humans, this viral agent has been accepted as zoonotic, but a complete transmission route has not been shown for its transmission from other animals to humans except bats. It is reported that there is no significant risk of transmission of the virus, which is transmitted primarily by the respiratory route, from both pets and edible foods to humans. Although there are many reports in terrestrial animals, studies on the presence of SARS-CoV-2 - in aquatic animals or aquatic environments and COVID-19 transmission in aquatic animals continue. Here we reviewed the viability of the SARS-CoV-2 - in the aquatic environment, transmission to the aquatic ecosystem and aquatic animals, and therefore the risks to humans through water or aquatic products.

  • A Study on Invasive Plant Species in Rize Urban Open Green Areas

    • Authors: Ömer Lütfü ÇORBACI; Erdi EKREN, Murat ATASOY
      Abstract: Plants, as the most important element of urban open and green areas, can have negative effects on the environment with some of their features, as well as many important benefits they offer to the urban ecosystem. Invasive plant taxa, which cause ecological problems and economic damage by negatively affecting the distribution and diversity of local species in the ecosystem they invade, are the most important examples that can be given in this regard. Invasive plant species are more competitive than other species due to their high tolerance for ecological factors, rapid growth, short life cycles and high reproductive capacity. These plants become dominant in the region in a short time and their populations reach epidemic levels. Therefore, it is necessary to detect and control invasive plants. Especially when choosing plants to be used in urban areas, in addition to their aesthetic and functional properties, whether they are invasive or not is an important criterion to be considered. There is not an adequate database of invasive plant species and diversity in Turkey. Within the scope of the study, it was aimed to determine the invasive plant taxa of Rize, one of the provinces with rich vegetation of the Black Sea Region, which is the most infested region of Turkey by exotic plants. A total of 85 different plant taxa with invasive properties were identified in Rize urban open green areas. These taxa were evaluated in terms of family, naturalness-exoticness status and location properties. In addition, various suggestions have been developed regarding the use of these plants in landscape architecture applications.

  • Investigation of Microplastic Removal Efficiency of Advanced Wastewater
           Treatment Methods

    • Authors: Ceyhun AKARSU
      Abstract: Microplastics, an anthropogenic pollutant, pass to wastewater treatment plants through sewage and then meet with the receiving environment. For this reason, wastewater treatment plants are seen as the primary source of microplastics in the aquatic environment and studies are carried out to determine the treatment efficiency of processes in existing plants. However, since it is not one of the microplastic facility design criteria, the removal efficiencies are not at the desired levels, so it is necessary to determine alternative treatment methods. In this context, studies are carried out on the determination of microplastic removal efficiency with advanced wastewater treatment methods in the literature. In this review, the treatment technologies used in these studies, which are quite new, are compared on their removal efficiencies and details about the removal mechanisms are given.

  • The Economic Analysis of The Nigerian Fisheries Sector: A Review

    • Authors: Edafe ODİOKO; Zehra Arzu BECER
      Abstract: The fisheries sector is an essential aspect of the world economy sector in terms of employment, food security, enterprise development, foreign exchange earnings, and important in terms of the livelihoods of many rural people and nutrition. Over 10% of the world population are economically dependent on fisheries as a source of employment, of which the majority are females. In Nigeria, over 764,615 people are reportedly engaged in the fisheries sector. The fisheries sector contributed 0.5% to the national GDP in 2015. The Nigerian fisheries sector is dependent on the artisanal fishers that produce over 68% of the nation’s total domestic production. It is an indication that this sector is not well utilized and developed. Nigeria is the world’s fourth-largest importer of fish products in terms of volume. Nigeria total fish imports of about $1.2 billion and exports valued at $284,390 million in 2013, make Nigeria a net importer of fishery products. In 2019, a shortfall in fish supply of about 1.3 million metric tons was met through imports. Relevant figures indicated that the value of fish imports keeps increasing which has been attributed to the increasing growth rate of the Nigerian population. From 2006 – 2010, the NBS reports showed that fish was the second major food commodity with the highest imports bills. The implication on importation to meet the national fish need ranges from health to socioeconomic impacts. The lack of attention in the fisheries sector is costing Nigeria the economic benefits this sector provides.

  • Determination Of Pigment Content And Antioxidant Activities Of Some
           Chlorophyta Species Isolated From Altınapa Dam Lake (Konya/ Turkey)

    • Authors: Baran AŞIKKUTLU; Cengiz AKKÖZ
      Abstract: Due to global warming, the decrease in water resources and the difficulties in reaching clean water are important problems for people today. New studies on water resources and the living creatures living in these water resources provide information about the status of these resources. Algae are necessary organisms for the survival of other living things in the environment because they provide oxygen to the environment they live in and form the first step of the food chain. Algae are very important living things because they are the primary producers in the aquatic ecosystems they are in. Due to these importance, many studies are carried out on microalgae. In this study, it was aimed to determine the chlorophyll-a, chlorophyll-b, total carotenoid content and antioxidant activities of some green algae species isolated from the benthic algae flora of Altınapa Dam Lake, which is one of the important drinking water sources of the city of Konya. Three Chlorophyta (Chlorella vulgaris, Acutodesmus obliquus, Monoraphidium minutum) species showing high growth potential under culture conditions were selected and studies were carried out with these species. Since Monoraphidium minutum species belonging to Chlorophyta, gives IC50 values close to the reference antioxidant, it has been concluded that it can provide an economic contribution in the food and pharmaceutical industries when produced under appropriate conditions.

  • Investigating the Presence of Salmonella spp. in the Feces of Red Deer
           (Cervus elaphus) in Istanbul

    • Authors: Cansu ENGİN; Mehmet Can ÖZTÜRK, Yalçın ABUL, Ilgın KEKEÇ, Arzu Funda BAĞCIGİL
      Abstract: Wildlife is an important source of many infectious agents for domestic animals and humans. Increasing interactions between humans, domestic animals, and wildlife may cause the infection of contagious agents between the species. Domestic animals can be easily infected with Salmonella serovars as a result of its asymptomatic presence in the intestinal flora of wild animals and its spreading around. The presence of Salmonella species in the feces of red deer, which is an important member of wildlife in Turkey, was investigated in the present study. A total of 240 fecal samples were collected in sterile dry plastic containers from free-ranging deer at the Deer Breeding Farm in Istanbul Belgrad Forest, at least once a month for a year. The samples collected were examined through conventional culture and molecular methods (PCR). Salmonella spp. was not isolated from the samples examined.

  • Determination of Proximate Composition and Fatty Acid Profiles of
           Commercial Fish Feeds

    • Authors: Koray KORKMAZ
      Abstract: The proximate composition and fatty acid profiles of the selected fish feeds (S, A, G3, and G6) prepared with different rations were investigated. The results showed that the crude protein, lipid, moisture, and ash level in feeds were in the range of 44.07% – 46.69%, 15.72% – 18.32%, 6.54% – 8.41% and 7.44% – 11.37%, respectively. The percentages of total saturated fatty acids (SFA) and total polyunsaturated fatty acids (PUFA) were higher in group A than in all other group, whereas the corresponding total monounsaturated fatty acids (MUFA) content was lower. All of the feeds had significant levels of polyunsaturated fatty acid (PUFA). The n6/n3 ratio of feeds was in the range of 1.15 - 1.98. The data obtained indicate that the % composition of n3 PUFAs was lower for G3 feed. These feeds were good sources of EPA (in the range of 3.13% - 4.57%) and DHA (in the range of 3.41% - 8.50%). Therefore, it was concluded that these fish feeds are suitable as a balanced food choice for aquaculture.

    • Authors: Elif ÇİL; Ceren BÖRÇEK KASURKA, Melek ÇOL AYVAZ
      Abstract: R. gracilis rhizomes were picked from Yenice Forests Karabük province in Turkey. Ethanol was chosen for extraction solvent. Disc diffusion method including filamentous and non-filamentous Gram-positive bacteria, Gram-negative bacteria, and yeast strains was used to evaluate the antimicrobial activity of the extract. DPPH free radical scavenging activity and ferric reducing antioxidant power analysis were performed to determine antioxidant activity. The Folin-Ciocalteu method for determining the total phenolic amount and the AlCl3 method for the total flavonoid content of the extract was chosen. Mean diameters of inhibition zones (IZD) of the bacteria were found in the range of 8.2 mm to 24.45 mm. This value was measured as 17.82 mm and 18.69 mm for yeasts. The total antioxidant activity value of the extract was calculated as 7.08 mg AAE/g extract. The IC50 value was found as 9.097 mg/mL for DPPH free radical scavenging activity. The FRAP value indicated that the reducing power of 1 gram of sample was equivalent to 4.66 μmol of Trolox. The total phenolic content of ethanol extract of R. gracilis rhizomes was determined as 0.414 mg GAE/g, while the flavonoid content was calculated as 0.68 mgQE/g. The analyzed ethanolic extract of R. gracilis rhizomes demonstrated that the biological activity level could be considered significant according to the obtained results.

  • Antibiotic Resistance of Gram-negative Heterotrophic Bacteria on the
           Marine Sediments of the Black Sea-Comparison of CLSI and EUCAST on the
           Environmental Isolates

    • Authors: Samet KALKAN
      Abstract: Marine sediments are the important reservoirs of antibiotics and resistant genes. Antibiotic resistance becomes a global concern today and bacteria from marine sediments show resistance to multiple microbial agents. This study investigates antibiotic resistance of Gram-negative heterotrophic bacteria from the marine sediment of the Black Sea. The samples were gathered from various sampling locations on the marine environments of the Black Sea between May 2019 and February 2020. The VITEK 2 system was utilized to detect the MIC values against different antibiotics automatically. The MIC values were ranged from 0.12 µg/ml to 80 µg/ml. The highest resistance ratios among all antibiotics were detected as 90% in CLSI and 81% in EUCAST against cefazolin. In general, the resistance ratios were determined as 13.4% in CLSI and 26.1% in EUCAST. All isolates were detected as susceptible to meropenem, cefepime, ceftazidime, colistin, ertapenem, and piperacillin/tazobactam. MAR indexes were ranged between 0 and 0.45. MAR index were detected above or equal the value of 0.2 as 27% in CLSI and 81% in EUCAST among all isolates. This study shows that EUCAST may be better than CLSI in terms of showing the antibiotic exposure among natural isolates and the MAR indexes may be a useful tool for defining the environmental status. The results of this study indicate that antibiotic resistance may be a serious concern in sediments of the Black Sea.

  • Packaging Methods Used in Aquaculture: Vacuum packaging, MAP, Biosensors,
           Oxygen Absorbing Labels

    • Authors: Mehmet Emin ERDEM; Nuri TUNÇTAŞ, Bayram KÖSTEKLİ, İrfan KESKİN
      Abstract: Packaging material is of great importance in preserving food and delivering it to the consumer in a healthy way. One of the most important features of packaging is that it informs the consumer about many information such as production place, content, production date and origin. Fisheries deteriorate very quickly as they are affected by all physical and environmental factors from the moment they are caught.. For this, it should be consumed as soon as possible, processed under appropriate conditions or packaged and delivered to the consumer in the best quality. In the rapidly growing fisheries sector, smart packaging, smart labels, biosensors, vacuum and modified packaging techniques, as well as oxygen absorbing labels have been developed. Microbiological quality measurement labels, pH sensors, radio frequency identification technology (RFID), data matrix applications as well as post-marketing follow-up of the products are also provided. With this work; It is aimed to give information about the packaging methods of fishery products and the usage areas of oxygen absorbing labels, RFID and biosensors.

  • Cloning and Determination of Kinetic Activity of Thermophilic GCH-I from
           Anoxybacillus flavithermus DSM 2641T

    • Authors: Fatih Şaban BERİŞ; Özlem HIZAL, Hakan KARAOĞLU
      Abstract: Phenylketonuria (PKU) is a disease caused by phenylalanine hydroxylase enzyme deficiency in newborn infants and is the most important cause of treatable mental retardation. One of the causes of the disease comes from the defects of the PTPS in the metabolic pathway of phenilalanine metabolisms. Treatment of the disease is not feasible, and life-time tetrahydrobiopterin loading is performed in chronic patients. Today, tetrahydrobiopterin is chemically synthesized. Biological production is a different point of view due to the long duration of chemical synthesis, costs, and exposure to chemical pollutants. For this reason, the gch-I gene from the thermophilic A. flavithermus DSM 2641T was identified by PCR method. We cloned the gchI gene that was 603 bp and its open reading frame has 200 amino acids. The gene was cloned into pET28a(+) expression vector with 6xHis tags and transform in E. coli BL21(DE3)pLys host cells to express with 1 mM IPTG induction. After purification with Ni-NTA resin, we determined that GCH-I is 24 kDa, its optimum pH is 8.0 and temperature is 65C.Under optimal conditions, GCH-I exhibited enzymatic activity with Km- and Vmax- values of 243 ± 23,25 μM and 100,93 ± 3,5 nM/min/mg protein, respectively.
