  • Isolation and Identification of Toluene Degrading Microbes and Detection
           of Catabolic Gene
    • Abstract: The present study reports on the isolation and characterization of new isolates from crude oil from petroleum contaminated soil. The isolates were then screened for their potential towards biodegradation of toluene by growing them in both solid as well as liquid mineral medium supplemented with toluene as a sole carbon source and further identified by GC-FAME analysis. The degradation potential of these isolates strongly suggests that the isolates have TOL like plasmid and carries xylM gene involved in the expression of the toluene monooxygenase. The primer sets were used in PCR to assess the presence of the catabolic gene in new toluene degrading isolates. The primer verification was done by using bioinformatics tools. From the results it is conclusive that isolates were able to degrade Toluene, and from PCR it is evident that the isolates contained gene coding for Toluene degradation. The test results indicate that the bacteria could contribute to bioremediation of aromatic hydrocarbon pollution.

  • Hepatoprotective Effect of Ethyl Acetate Extract of Vitex doniana Stem
           Bark on Carbon Tetrachloride (CCl4) Induced Liver Damage in Wistar Rats
    • Abstract: The hepatoprotective effect of Ethyl Acetate Extract of Vitex doniana (EAEVD) stem bark on carbon tetrachloride (CCl4) induced hepatic damage was studied, to evaluate some biochemical parameters, to determine the in vitro antioxidant effect of the extract on Superoxide Dismutase (SOD), Catalase (CAT) glutathione peroxidase (GPX) and glutathione-s-transferase (GST) and to quantify the levels of some phytochemicals present in EAEVD stem bark. A total of twenty four Rats were used for the study. Animals in group1 served as vehicle control, Group 2 served as hepatotoxin (CCL4) treated group, Group 3 served as positive control (Sylimarin) treated group, Group 4 was administered with 100 (mg kg-1 b.wt.) of the extract and group 5 was administered with 200 (mg kg-1 b.wt.) of the extract After the experimental period of 14 days. The animals were sacrificed, blood and liver samples were collected and used for the evaluation of the following biochemical parameters Aspartate amino transferase (AST), Alanine amino transaminase (ALT) and Alkaline phosphatase (ALP) in serum, as well as thiobarbituric acidreactive substances (TBARS), lipidhydroperoxides superoxide dismutase (SOD), catalase (CAT) glutathione peroxidase (GPX) and glutathione-s-transferase (GST) in the liver. Administration of 100 and 200 mg kg-1 b.wt. (EAEVD) significantly decreased (p

  • Chemopreventive Effect of Curcumin on Oxidative Stress, Antioxidant
           Status, DNA Fragmentation and Caspase-9 Gene Expression in
           1,2-dimethylhydrazine-induced Colon Cancer in Rats
    • Abstract: The present study was designed to investigate the ameliorative effect of curcumin administration on oxidative stress, antioxidant status, DNA fragmentation and caspase-9 gene expression in colon cancer induced by 1, 2-dimethylhydrazine (DMH) in rats. Seventy male albino rats divided into five groups containing 14 rats each. Group 1: (Control group) rats received no drugs. Group 2: (colon cancer induced group) rats injected DMH (35 mg kg-1 b.wt week-1, subcutaneously) for ten weeks. Group 3: (DMH+curcumin therapeutic group) rats injected DMH and administered curcumin (100 mg kg-1 b.wt. day-1, orally) from the 11th week until the 16th weeks. Group 4: ( DMH+curcumin treated group) rats injected DMH and at the same time administered curcumin for 16 weeks ( end of experiment). Group 5: (control+curcumin group) rats administered curcumin all over the experimental periods. At the end of 16th week treatment blood samples and colon tissues were collected for determination of serum lactate dehydrogenase (LDH) and Carcino Embryonic Antigen (CEA) in addition to Glutathione Peroxidase (GPx), catalase (CAT), superoxide dismutase (SOD), reduced glutathione (GSH), L-malondialdehyde (L-MDA), Nitric Oxide (NO), glutathione-S-transferase (GST), Caspase-9 gene and DNA fragmentation in colon tissues. The obtained results revealed that, DMH potentially increased serum LDH activity and CEA level. In addition, CAT, GPx, GST activities, MDA and NO concentrations in colon tissues of DMH injected rats were significantly increased. However, SOD, GSH, Caspase-9 and DNA fragmentation in colon tissues were significantly decreased. Curcumin treatment to colon cancer rats significantly decreased serum LDH and CEA, CAT and GPx activities and attenuated the increased MDA and NO concentrations in colon tissues. On the other hand, curcumin treatment enhanced the activity of SOD and GST and the level of GSH, caspase-9 and DNA fragmentation in colon tissues. From the obtained results it could be concluded that, inhibition of peroxidation and oxidative stress markers and enhanced antioxidant status and increased caspase-9 gene expression and DNA fragmentation in rat colon tissues by curcumin suggest the potential efficacy of curcumin as an addition chemopreventive agent in treatment of colon carcinogenesis.

  • Engineered Variants of Streptokinase: Molecular Analysis of Their
           Plasminogen Activation and Proteolytic Processing
    • Abstract: Streptokinase (SK) is a major blood-dissolving agent that used in the treatment of various circulatory disorders. Since the original host of Streptokinase is pathogenic and secretes several toxins which complicate the purification, (SK) gene was cloned in a strain of Bacillus subtilis as a nonpathogenic expression system. The role of the promoter and signal sequence of B. subtilis in the production of streptokinase was assessed by two different constructs, (vSKa) and (vSKb). Secreted streptokinase from both constructs were analyzed and specific activity of sucrose induced streptokinase from the construct of (vSKb) was about 1.2 to 1.4 fold higher than that from (vSKa). Streptokinase produced from (vSKa) and vSKb has an N-terminal sequence identical to the native streptokinase of S. equismilis H46A. Upon incubation of the immobilized plasmin (hPlm) with SK, several peptide fragments were observed by PAGE electrophoresis. After purification, molecular masses and the N-terminal sequences of these fragments were determined. Data obtained from these sequences indicated that there are different processing sites. To prevent proteolytic processing of SK at the C-terminus, two variants (SK1 and SK2) were engineered via site directed mutagenesis. Characterization of streptokinase derived from SK1 and SK2 by Western blot analysis demonstrated that both variants were resistant to the proteolytic processing but a low percentage (10-20%) of the secreted streptokinase from SK1 appeared in a degraded form. However, variant of SK2, showed a biological activity 2.5 times higher than that of the wild-type streptokinase. To prevent processing of SK at the N-terminus, Lys59 in SK2 was changed by site directed mutagenesis either to glutamine yielding the mutant variant SK2K59Q or glutamic acid yielding SK2K59E. Purified SK protein from SK2K59Q was resistance to proteolysis by (hPlm) and showed better plasminogen activation in the radial caseinolysis assay. This study indicates that blocking of the N-terminal cleavage at K59 site is critical to generate a proteolytic-resistant streptokinase variant.

  • Applications of Analytical Instruments in Biotechnology: A Comparative
           Review
    • Abstract: Knowing the appropriate applications of various analytical techniques used in biotechnology, makes the experiment more easier and let the researcher obtain a better result which also reduces the time period of experiment by eliminating the trial and error methods. Along with the knowledge of application of the analytical technique, the researcher also should have the knowledge of the sampling techniques for the analytical instruments as it is one of the deciding factors to choose a specific technique for the analysis. At the same time, the results obtained by using the analytical equipments are relatively authentic and accurate. With the development of biotechnology, the usage of analytical equipments has increased by many folds. The areas of biotechnology such as nanotechnology, cancer biology, genetic engineering and many more are dependent on the analytical equipments for most of their experimental analysis. Analytical equipments find its application not only in the research works but also at the industry level. Various food and pharmaceutical industries rely upon the analytical techniques like FT-IR and Raman for the quality analysis of the products.
