“…This enzyme can be arranged into four categories. The Group I H 2 ‐consuming membrane‐bound hupSL hydrogenase is found in both aerobic and anaerobic bacteria ( Aquefixaeolicus ) with an electron transport system via cytochromes 1, 101. This enzyme structure is recognized by a signal peptide linked at the N ‐terminus of a small subunit 29, 101.…”

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.

“…In this line of research thinking, and notwithstanding the valuable pool of findings which have been accumulated so far on the pretreatment techniques studied in terms of their merits and demerits which can be reasonably addressed, the trend in the specific field of research and development in biohydrogen production from biomass has been to explore combined physicochemical pretreatment schemes which have a strong connection with the 'green chemistry' elements. This is because there has been a start in the use of microwave-assisted, ultrasound-assisted (Budiman et al, 2017a) One more green form of irradiation which has been continually getting attention in biomass pretreatment for its main advantages in improving the process dynamics is ultrasound irradiation (i.e. sonication).…”

Different types of biomass are being examined for their optimum hydrogen production potentials and actual hydrogen yields in different experimental setups and through different chemical synthetic routes. In this review, the observations emanating from research findings on the assessment of hydrogen synthesis kinetics during fermentation and gasification of different types of biomass substrates have been concisely surveyed from selected publications. This review revisits the recent progress reported in biomass-based hydrogen synthesis in the 2 associated disciplines of microbial cell immobilization, bioreactor design and analysis, ultrasound-assisted, microwave-assisted and ionic liquid-assisted biomass pretreatments, development of new microbial strains, integrated production schemes, applications of nanocatalysis, subcritical and supercritical water processing, use of algae-based substrates and lastly inhibitor detoxification. The main observations from this review are that cell immobilization assists in optimizing the biomass fermentation performance by enhancing bead size, providing for adequate cell loading and improving mass transfer; there are novel and more potent bacterial and fungal strains which improve the fermentation process and impact on hydrogen yields positively; application of microwave irradiation and sonication and the use of ionic liquids in biomass pretreatment bring about enhanced delignification, and that supercritical water biomass processing and dosing with metal-based nanoparticles also assist in enhancing the kinetics of hydrogen synthesis. The research areas discussed in this work and their respective impacts on hydrogen synthesis from biomass are arguably standalone. Thence, further work is still required to explore the possibilities and techno-economic implications of combining these areas for developing robust and integrated biomass-to-hydrogen synthetic schemes.

“…Value-Added Materials. Using Rhodobacter sphaeroide as purple nonsulfur bacteria to yield biohydrogen in the photo-fermentation process, Budiman et al (2017) found that introducing ultrasonication intermittently onto broth improved the photo-fermentative biohydrogen production. Intermittent conditions of 20 A amplitude and 10 minutes duration produced 14.438 mL H2 / mLmedium with 7.41% light efficiency.…”
