As of 2023, coal, oil, and natural gas, which are non-renewable fossil fuels, account for about 80% the world’s energy consumption. This underscores pressing necessity alternative sources in light worsening climate crisis. Apart from problems, this review evaluates potential microbial fuel cells biofuel production, contributes to just 10–20% total consumption due its relatively low environmental impact. The aim systematic is elucidate their role producing a range bio-based including biogas, biodiesel, bioethanol, biobutanol. findings categorized into ten main areas: biomass conversion techniques, substrates strains, design components cells, strain improvement through metabolic engineering, enhancements nanomaterials advantages disadvantages biofuels, integration biorefineries, applications, challenges limitations, future trends cell technology. also promise as sustainable eco-friendly option bioenergy emphasizing need advancements efficiency compete with conventional fuels. Harnessing innovative strategies pertaining technology (MFCs) can potentially transform generation more commercially viable practice, positively impacting conservation public health.

ABSTRACT Thermoanaerobacterium saccharolyticum is a thermophilic anaerobic bacterium that natively ferments variety of hemicellulose substrates to organic acids and alcohols. It has recently been engineered produce ethanol at high yield titer; however, it uses unique metabolic pathway for production poorly characterized. One the distinctive aspects this presence acetyl-CoA as an intermediate metabolite. In organism, converted by bifunctional AdhE enzyme. This enzyme frequent target mutations, in many cases, function these mutations was unknown. Using combination genetic modifications, assays, computational analysis, we have developed better understanding how affect homoethanologen strain. We identify set approximately interchangeable (G544D, T597K, T597I, T605I), whose disrupt activity alcohol dehydrogenase (ADH) domain AdhE. reduces NADH-linked ADH activity, which dramatically increases tolerance changes overall stoichiometry acetaldehyde conversion. Furthermore, our improved calls into question proposed feature enzymes known substrate channeling—direct transfer between two domains role T. provides deeper insights organism. IMPORTANCE Many bacteria maintain redox equilibrium producing reduced compounds such ethanol. The final steps are mediated enzyme, AdhE, strains increased production. Paradoxically, increase eliminating one (the domain). additional support redox-imbalance theory tolerance, challenges prevailing hypothesis associated with cell membrane effects.

Biohydrogen (bioH 2 ) production in rural regions of the United States leveraged from existing biomass waste streams serves two extant needs: energy resiliency and decarbonization heavy industry, including ammonia other H -dependent nitrogenous products. We consider bioH using different strategies: (1) dark fermentation (DF) (2) anaerobic digestion followed by steam methane reforming biogas (AD-SMR). Production is a potentially ‘greener’ pathway comparison to natural gas-steam (NG-SMR), especially as fugitive emissions these wastes are avoided. It also provides decarbonizing potential not found water-splitting technologies. Based on literature DF AD crop residues, woody residues forestry wastes, wastewaters containing fats, oils, grease (FOG), we outline scenarios for displacement fossil fuel derived methane. Finally, compare costs carbon intensity (CI) with those pathways.

Solventogenic Clostridium species are important for establishing the sustainable industrial bioproduction of fuels and chemicals such as acetone butanol. The inherent versatility these in substrate utilization range solvents produced during butanol–ethanol (ABE) fermentation make solventogenic an attractive choice biotechnological applications production chemicals. functional qualities microbes have thus been identified to be related complex regulatory networks that play essential roles modulating metabolism this group bacteria. Yet, still struggle consistently achieve butanol concentrations exceeding 20 g/L batch fermentation, primarily due toxic effects on culture. Genomes a relatively greater prevalence genes intricately controlled by various molecules than most other species. Consequently, use genetic or metabolic engineering strategies do not consider underlying mechanisms will effective. Several factors involved uptake/utilization, sporulation, solvent production, stress responses (Carbon Catabolite Protein A, Spo0A, AbrB, Rex, CsrA) characterized. In review, focus is newly species, interaction with previously molecules, potential implications utilization, resistance/tolerance lignocellulose-derived microbial inhibitory compounds. Taken together, review anticipated highlight challenges impeding re-industrialization ABE inspire researchers generate innovative overcoming obstacles.
