This review explores biohydrogen (bio-H2) production from microorganisms. While promising for clean energy, current yields are insufficient, highlighting the need for further research and development in this sustainable fuel source.
Area of Science:
- Biotechnology and Renewable Energy
Background:
- Hydrogen (H2) is a sustainable energy source crucial for future transportation.
- Current microbial H2 yields are insufficient for widespread adoption.
Purpose of the Study:
- To review recent advancements in biohydrogen (bio-H2) production.
- To highlight challenges and potential of various bio-H2 pathways.
Main Methods:
- Overview of four primary bio-H2 production pathways: direct and indirect photolysis, photo-fermentation, and dark anaerobic fermentation.
- Analysis of fundamental research and applied studies in bio-H2 production.
Main Results:
- Dark anaerobic fermentation shows significant potential for practical applications, including organic waste treatment.
- Recent studies have focused on improving microbial H2 yields.
Conclusions:
- Biohydrogen production is a key area for developing sustainable energy solutions.
- Further research is needed to overcome yield limitations and optimize production processes.

Fates of Pyruvate
In aerobic organisms, pyruvate is metabolized via the citric acid cycle to produce reduced coenzymes NADH and FADH2. These coenzymes are then oxidized in the electron transport chain to produce ATP and, in the process, regenerate the NAD+ and FAD. As seen in some cell types and organisms, fermentation...
