  • Electrochemical Bioreactor Technology for Biocatalysis and Microbial
           Electrosynthesis
    • Abstract: Publication date: Available online 6 September 2018Source: Advances in Applied MicrobiologyAuthor(s): Clifford Morrison, Elizabeth Heitmann, William Armiger, David Dodds, Mattheos Koffas Two seemingly distinct fields, industrial biocatalysis and microbial electrosynthesis, can be viewed together through the lens of electrochemical bioreactor technology in order to highlight the challenges that exist in creating a versatile platform technology for use in chemical and biological applications. Industrial biocatalysis applications requiring NAD(P)H to perform redox transformations often necessitate convoluted coupled-enzyme regeneration systems to regenerate reduced cofactor, NAD(P)H from oxidized cofactor, NAD(P). Renewed interest in continuously recycling the cofactor via electrochemical reduction is motivated by the low cost of performing electrochemical reactions, easy monitoring of the reaction progress, and straightforward product recovery. However, electrochemical cofactor regeneration methods invariably produce adventitious reduced cofactor side products which result in unproductive loss of input NAD(P). Microbial electrosynthesis is a form of microbially driven catalysis in which electricity is supplied to living microorganisms for the production of industrially relevant chemical products at higher carbon efficiencies and yields compared with traditional, nonelectrically driven, fermentations. The fundamental biochemistry of these organisms as related to selected biochemical redox processes will be explored in order to highlight opportunities to devise strategies for taking advantage of these biochemical processes in engineered systems.
       
  • Diversity-Function Relationships in Natural, Applied, and Engineered
           Microbial Ecosystems
    • Abstract: Publication date: Available online 9 August 2018Source: Advances in Applied MicrobiologyAuthor(s): Andrew Free, Michael A. McDonald, Eulyn Pagaling The connection between ecosystem function and taxonomic diversity has been of interest and relevance to macroecologists for decades. After many years of lagging behind due to the difficulty of assigning both taxonomy and function to poorly distinguishable microscopic cells, microbial ecology now has access to a suite of powerful molecular tools which allow its practitioners to generate data relating to diversity and function of a microbial community on an unprecedented scale. Instead, the problem facing today's microbial ecologists is coupling the ease of generation of these datasets with the formulation and testing of workable hypotheses relating the diversity and function of environmental, host-associated, and engineered microbial communities.Here, we review the current state of knowledge regarding the links between taxonomic alpha- and beta-diversity and ecosystem function, comparing our knowledge in this area to that obtained by macroecologists who use more traditional techniques. We consider the methodologies that can be applied to study these properties and how successful they are at linking function to diversity, using examples from the study of model microbial ecosystems, methanogenic bioreactors (anaerobic digesters), and host-associated microbiota. Finally, we assess ways in which our newly acquired understanding might be used to manipulate diversity in ecosystems of interest in order to improve function for the benefit of us or the environment in general through the provision of ecosystem services.
       
  • Ecology of Contaminant Biotransformation in the Mycosphere: Role of
           Transport Processes
    • Abstract: Publication date: Available online 3 July 2018Source: Advances in Applied MicrobiologyAuthor(s): Anja Worrich, Lukas Y. Wick, Thomas Banitz Fungi and bacteria often share common microhabitats. Their co-occurrence and coevolution give rise to manifold ecological interactions in the mycosphere, here defined as the microhabitats surrounding and affected by hyphae and mycelia. The extensive structure of mycelia provides ideal “logistic networks” for transport of bacteria and matter in structurally and chemically heterogeneous soil ecosystems. We describe the characteristics of the mycosphere as a unique and highly dynamic bacterial habitat and a hot spot for contaminant biotransformation. In particular, we emphasize the role of the mycosphere for (i) bacterial dispersal and colonization of subsurface interfaces and new habitats, (ii) matter transport processes and contaminant bioaccessibility, and (iii) the functional stability of microbial ecosystems when exposed to environmental fluctuations such as stress or disturbances. Adopting concepts from ecological theory, the chapter disentangles bacterial–fungal impacts on contaminant biotransformation in a systemic approach that interlinks empirical data from microbial ecosystems with simulation data from computational models. This approach provides generic information on key factors, processes, and ecological principles that drive microbial contaminant biotransformation in soil. We highlight that the transport processes create favorable habitat conditions for efficient bacterial contaminant degradation in the mycosphere. In-depth observation, understanding, and prediction of the role of mycosphere transport processes will support the use of bacterial–fungal interactions in nature-based solutions for contaminant biotransformation in natural and man-made ecosystems, respectively.
       
  • Enhancing Yeast Alcoholic Fermentations
    • Abstract: Publication date: Available online 14 June 2018Source: Advances in Applied MicrobiologyAuthor(s): Graeme M. Walker, Roy S.K. Walker The production of ethanol by yeast fermentation represents the largest of all global biotechnologies. Consequently, the yeast Saccharomyces cerevisiae is the world's premier industrial microorganism, which is responsible not only for the production of alcoholic beverages, including beer, wine, and distilled spirits, but also for the billions of liters of bioethanol produced annually for use as a renewable transportation fuel. Although humankind has exploited the fermentative activities of yeasts for millennia, many aspects of alcohol fermentation remain poorly understood. This chapter will review some of the key considerations in optimizing industrial alcohol fermentations with a particular emphasis on enhancement opportunities involving cell physiology and strain engineering of the major microbial ethanologen, the yeast S. cerevisiae.
       
  • The Genus Macrococcus: An Insight Into Its Biology, Evolution, and
           Relationship With Staphylococcus
    • Abstract: Publication date: Available online 13 June 2018Source: Advances in Applied MicrobiologyAuthor(s): Shahneela Mazhar, Colin Hill, Olivia McAuliffe The Gram-positive genus Macrococcus is composed of eight species that are evolutionarily closely related to species of the Staphylococcus genus. In contrast to Staphylococcus species, species of Macrococcus are generally regarded to be avirulent in their animal hosts. Recent reports on Macrococcus have focused on the presence of novel methicillin resistance genes in Macrococcus caseolyticus and Macrococcus canis, with the discovery of the first plasmid-encoded methicillin resistance gene in clinical Staphylococcus aureus of probable macrococcal origin generating further interest in these organisms. Furthermore, M. caseolyticus has been associated with flavor development in certain fermented foods and its potential as a food bio-preservative has been documented. The potential application of these organisms in food seems at odds with the emerging information regarding antibiotic resistance and is prompting further examination of the potential safety issues associated with such strains, given the European Food Safety Authority framework for the safety evaluation of microorganisms in the food chain. A comprehensive understanding of the genus would also contribute to understanding the evolution of staphylococci in terms of its acquisition of antibiotic resistance and pathogenic potential. In this review, we discuss the current knowledge on Macrococcus with regard to their phenotypic capabilities, genetic diversity, and evolutionary history with Staphylococcus. Comparative genomics of the sequenced Macrococcus species will be discussed, providing insight into their unique metabolic features and the genetic structures carrying methicillin resistance. An in-depth understanding of these antibiotic resistance determinants can open the possibilities for devising better preventative strategies for an unpredictable future.
       
  • Applications of Microbial Processes in Geotechnical Engineering
    • Abstract: Publication date: Available online 13 June 2018Source: Advances in Applied MicrobiologyAuthor(s): G. El Mountassir, J.M. Minto, L.A. van Paassen, E. Salifu, R.J. Lunn Over the last 10–15 years, a new field of “biogeotechnics” has emerged as geotechnical engineers seek to find ground improvement technologies which have the potential to be lower carbon, more ecologically friendly, and more cost-effective than existing practices. This review summarizes the developments which have occurred in this new field, outlining in particular the microbial processes which have been shown to be most promising for altering the hydraulic and mechanical responses of soils and rocks. Much of the research effort in this new field has been focused on microbially induced carbonate precipitation (MICP) via ureolysis, while a comprehensive review of MICP is presented here, the developments which have been made regarding other microbial processes, including MICP via denitrification and biogenic gas generation are also presented. Furthermore, this review outlines a new area of study: the potential deployment of fungi in geotechnical applications which has until now been unexplored.
       
  • Epigenetic and Posttranslational Modifications in Regulating the Biology
           of Aspergillus Species
    • Abstract: Publication date: Available online 7 June 2018Source: Advances in Applied MicrobiologyAuthor(s): Xinyi Nie, Bowen Li, Shihua Wang Epigenetic and posttranslational modifications have been proved to participate in multiple cellular processes and suggested to be an important regulatory mechanism on transcription of genes in eukaryotes. However, our knowledge about epigenetic and posttranslational modifications mainly comes from the studies of yeasts, plants, and animals. Recently, epigenetic and posttranslational modifications have also raised concern for the relevance of regulating fungal biology in Aspergillus. Emerging evidence indicates that these modifications could be a connection between genetic elements and environmental factors, and their combined effects may finally lead to fungal phenotypical changes. This article describes the advances in typical DNA and protein modifications in the genus Aspergillus, focusing on methylation, acetylation, phosphorylation, ubiquitination, sumoylation, and neddylation.
       
  • Salmonella Cold Stress Response: Mechanisms and Occurrence in
           Foods
    • Abstract: Publication date: Available online 11 May 2018Source: Advances in Applied MicrobiologyAuthor(s): Steven C. Ricke, Turki M. Dawoud, Sun Ae Kim, Si Hong Park, Young Min Kwon Since bacteria in foods often encounter various cold environments during food processing, such as chilling, cold chain distribution, and cold storage, lower temperatures can become a major stress environment for foodborne pathogens. Bacterial responses in stressful environments have been considered in the past, but now the importance of stress responses at the molecular level is becoming recognized. Documenting how bacterial changes occur at the molecular level may help to achieve the in-depth understanding of stress responses, to predict microbial fate when they encounter cold temperatures, and to design and develop more effective strategies to control pathogens in food for ensuring food safety. Microorganisms differ in responding to a sudden downshift in temperature and this, in turn, impacts their metabolic processes and can cause various structural modifications. In this review, the fundamental aspects of bacterial cold stress responses focused on cell membrane modification, DNA supercoiling modification, transcriptional and translational responses, cold-induced protein synthesis including CspA, CsdA, NusA, DnaA, RecA, RbfA, PNPase, KsgA, SrmB, trigger factors, and initiation factors are discussed. In this context, specific Salmonella responses to cold temperature including growth, injury, and survival and their physiological and genetic responses to cold environments with a focus on cross-protection, different gene expression levels, and virulence factors will be discussed.
       
  • Enhancement of Metallosphaera sedula Bioleaching by Targeted Recombination
           and Adaptive Laboratory Evolution
    • Abstract: Publication date: Available online 7 May 2018Source: Advances in Applied MicrobiologyAuthor(s): Samuel McCarthy, Chenbing Ai, Paul Blum Thermophilic and lithoautotrophic archaea such as Metallosphaera sedula occupy acidic, metal-rich environments and are used in biomining processes. Biotechnological approaches could accelerate these processes and improve metal recovery by biomining organisms, but systems for genetic manipulation in these organisms are currently lacking. To gain a better understanding of the interplay between metal resistance, autotrophy, and lithotrophic metabolism, a genetic system was developed for M. sedula and used to evaluate parameters governing the efficiency of copper bioleaching. Additionally, adaptive laboratory evolution was used to select for naturally evolved M. sedula cell lines with desirable phenotypes for biomining, and these adapted cell lines were shown to have increased bioleaching capacity and efficiency. Genomic methods were used to analyze mutations that led to resistance in the experimentally evolved cell lines, while transcriptomics was used to examine changes in stress-inducible gene expression specific to the environmental conditions.
       
  • Chapter Four - Bacterial Anaerobic Synthesis Gas (Syngas) and CO2 + H2
           Fermentation
    • Abstract: Publication date: 2018Source: Advances in Applied Microbiology, Volume 103Author(s): Frank R. Bengelsdorf, Matthias H. Beck, Catarina Erz, Sabrina Hoffmeister, Michael M. Karl, Peter Riegler, Steffen Wirth, Anja Poehlein, Dirk Weuster-Botz, Peter Dürre Anaerobic bacterial gas fermentation gains broad interest in various scientific, social, and industrial fields. This microbial process is carried out by a specific group of bacterial strains called acetogens. All these strains employ the Wood–Ljungdahl pathway but they belong to different taxonomic groups. Here we provide an overview of the metabolism of acetogens and naturally occurring products. Characteristics of 61 strains were summarized and selected acetogens described in detail. Acetobacterium woodii, Clostridium ljungdahlii, and Moorella thermoacetica serve as model organisms. Results of approaches such as genome-scale modeling, proteomics, and transcriptomics are discussed. Metabolic engineering of acetogens can be used to expand the product portfolio to platform chemicals and to study different aspects of cell physiology. Moreover, the fermentation of gases requires specific reactor configurations and the development of the respective technology, which can be used for an industrial application. Even though the overall process will have a positive effect on climate, since waste and greenhouse gases could be converted into commodity chemicals, some legislative barriers exist, which hamper successful exploitation of this technology.
       
  • Chapter Five - Biofilm: A Hotspot for Emerging Bacterial Genotypes
    • Abstract: Publication date: 2018Source: Advances in Applied Microbiology, Volume 103Author(s): Live L. Nesse, Roger Simm Bacteria have the ability to adapt to changing environments through rapid evolution mediated by modification of existing genetic information, as well as by horizontal gene transfer (HGT). This makes bacteria a highly successful life form when it comes to survival. Unfortunately, this genetic plasticity may result in emergence and dissemination of antimicrobial resistance and virulence genes, and even the creation of multiresistant “superbugs” which may pose serious threats to public health. As bacteria commonly reside in biofilms, there has been an increased interest in studying these phenomena within biofilms in recent years. This review summarizes the present knowledge within this important area of research.Studies on bacterial evolution in biofilms have shown that mature biofilms develop into diverse communities over time. There is growing evidence that the biofilm lifestyle may be more mutagenic than planktonic growth. Furthermore, all three main mechanisms for HGT have been observed in biofilms. This has been shown to occur both within and between bacterial species, and higher transfer rates in biofilms than in planktonic cultures were detected. Of special concern are the observations that mutants with increased antibiotic resistance occur at higher frequency in biofilms than in planktonic cultures even in the absence of antibiotic exposure. Likewise, efficient dissemination of antimicrobial resistance genes, as well as virulence genes, has been observed within the biofilm environment. This new knowledge emphasizes the importance of biofilm awareness and control.
       
  • Chapter Three - Modeling Bacteria–Phage Interactions and Its
           Implications for Phage Therapy
    • Abstract: Publication date: 2018Source: Advances in Applied Microbiology, Volume 103Author(s): Saptarshi Sinha, Rajdeep K. Grewal, Soumen Roy Bacteriophages are more abundant than any other organism on our planet. The interaction of bacteriophages and bacteria and their coevolution is well known. In this chapter, we describe various aspects of modeling such systems and their dynamics. We explore their interaction in: (i) liquid media, which leads to well-mixed populations and (ii) solid media, where their interaction is spatially restricted. Such modeling, when used in conjunction with experiments would not only shed deep insight into the underlying dynamics but also provide useful clues toward potential therapeutic applications.
       
  • Chapter Two - Microbial Source Tracking of Cronobacter spp.
    • Abstract: Publication date: 2018Source: Advances in Applied Microbiology, Volume 103Author(s): Steve Forsythe Being able to track bacterial pathogens is essential for epidemiological purposes as well as monitoring in-house production facilities. Common bacterial pathogens, such as Salmonella serovars, are already been well defined, and their detection methods are very advanced. However, this will not be the case for emergent bacterial pathogens, as was the case for Cronobacter. The clinical significance of the organism is due to its association with rare sporadic infections in adults, and severe life-threatening outbreaks of necrotizing enterocolitis and meningitis in newborn babies. The main recognized route of infection being through the consumption of contaminated reconstituted powdered infant formula. Key to the advances in being able to track this organism during formula production and outbreaks in neonatal intensive care units has been the use of DNA sequence-based methods, and most recently those which profile whole-genome sequences.This chapter considers how the latest DNA sequence-based methods in genotyping Cronobacter serve as a model for analyzing emergent bacterial pathogens in the future. The methods considered will initially highlight the limitations of phenotyping, then advance from the DNA probe-based methods for serotyping through to DNA sequence-based methods, especially multilocus sequence typing which is supported by an open access database. Finally the development of typing methods based on whole-genomes sequences, CRISPR-cas array profiling and SNP analysis, will be covered. The overall perspective is that emergent pathogens need to be investigated with the most advanced methods in order for robust and reliable control measures to be adopted.
       
  • Chapter One - Antimicrobial Resistance in Campylobacter Species:
           Mechanisms and Genomic Epidemiology
    • Abstract: Publication date: 2018Source: Advances in Applied Microbiology, Volume 103Author(s): Chris A. Whitehouse, Shaohua Zhao, Heather Tate The Campylobacter genus is a large and diverse group of Gram-negative bacteria that are known to colonize humans and other mammals, birds, reptiles, and shellfish. While it is now recognized that several emerging Campylobacter species can be associated with human disease, two species, C. jejuni and C. coli, are responsible for the vast majority of bacterial gastroenteritis in humans worldwide. Infection with C. jejuni, in particular, has also been associated with a number of extragastrointestinal manifestations and autoimmune conditions, most notably Guillain–Barré syndrome. The antimicrobial drugs of choice for the treatment of severe Campylobacter infection include macrolides, such as erythromycin, clarithromycin, or azithromycin. Fluoroquinolones, such as ciprofloxacin, are also commonly used for empirical treatment of undiagnosed diarrheal disease. However, resistance to these and other classes of antimicrobial drugs is increasing and is a major public health problem. The US Centers for Disease Control and Prevention estimates that over 300,000 infections per year are caused by drug-resistant Campylobacter. In this chapter, we discuss the taxonomy of the Campylobacter genus, the clinical and global epidemiological aspects of Campylobacter infection, with an emphasis on C. jejuni and C. coli, and issues related to the treatment of infection and antimicrobial resistance mechanisms. We further discuss the use of next-generation sequencing for the detection and surveillance of antimicrobial resistance genes.
