Biotechnology for Biofuels and Bioproducts is an open access peer-reviewed journal featuring studies describing advancements in fundamental understanding, technological capabilities, and technoeconomic & life cycle assessment of the production of biofuels, biochemicals and biomaterials. The journal emphasizes understanding and advancing the application of biotechnology, bioengineering, and genetics to improve plant, algae, and other carbonaceous feedstocks, as well as devised conversion systems. Their improvement is of critical relevance to the biological production of biofuels, biochemicals, and biomaterials derived from plant or aquatic biomass, intermediates derived from biomass, or CO2. Biotechnology for Biofuels and Bioproducts focuses on the following areas: • Anaerobic digestion of waste • Bacterial and fungal/yeast genetics, physiology, and metabolic engineering • Biohydrogen and bioelectricity (fuel cells) • Biological and chemical upgrading of biomass sugars, lignins and other biomass-derived intermediates • Biomass pretreatment, fractionation, and extraction • Bioprocess integration, biohybrid processes and technoeconomic analysis • Cell free and immobilized enzyme processes • Development of terrestrial plant and algal feedstocks • Enzyme engineering, production, and analysis (including cell free and immobilized enzyme processes) • Fermentation, biocatalytic conversion, and reaction dynamics • Life cycle assessment and environmental impact analysis Section Topics covered Anaerobic Digestion of Waste Anaerobic Digestion of Waste focuses on the microbes and microbial communities that drive conversion of organic waste under anoxic conditions. This topic includes microbial ecology, syntrophy, methanogenesis, pathway engineering, community dynamics, inhibition and resilience, and strategies to improve digester performance through better understanding or control of the biology. Bacterial and fungal/yeast genetics, physiology, and metabolic engineering Bacterial and fungal/yeast genetics, physiology, and metabolic engineering focuses on understanding and engineering microbial function for improved bioconversion and bioproduct formation. This includes studies on gene regulation, metabolism, stress responses, host physiology, pathway design, strain engineering, and systems-level approaches in bacteria, fungi, and yeasts. Biohydrogen and bioelectricity (fuel cells) Biohydrogen and bioelectricity focuses on microbes, enzymes, and redox-active biological systems that produce hydrogen or generate electrical current. This includes microbial hydrogen metabolism, hydrogenases and related enzymes, fermentative and photobiological hydrogen production, electroactive organisms, microbial fuel cells, extracellular electron transfer, redox mediators, and strategies to improve biological energy conversion.
