Microorganism-Assisted Biohydrogen Production and Bioreactors

Microorganism-assisted biohydrogen (BioH(2)) is an encouraging replacement of fossil-based fuels as feasible preference for various chemical and mechanical processes. BioH(2) is capable to reduce greenhouse gas emissions and solve environmental issues, therefore, numerous studies addressed optimization of operation design, microbial actions, certain addition of chemicals or nanoparticles, pretreatment of algal biomass, diminishing sensibility of enzymes towards O-2, integration with different processes for biorefinery approach, reducing costs, bioelectrochemical cell membranes, and others. The present review focuses on model organisms employed for the microorganism-assisted biohydrogen production. Metabolic pathways such as biophotolysis, photofermentation, and dark fermentation were discussed for providing deep insight of microorganism-aided biohydrogen production.

Automated summary

Microorganism-assisted biohydrogen is a promising alternative to fossil-based fuels, capable of reducing greenhouse gas emissions and addressing environmental issues. This review focuses on model organisms and metabolic pathways involved in microorganism-assisted biohydrogen production.
