Sustainable production of algae-bacteria granular consortia based biological hydrogen: New insights

Microbes recycling nutrient and detoxifying ecosystems are capable to fulfil the future energy need by producing biohydrogen by due to the coupling of autotrophic and heterotrophic microbes. In granules microbes mutualy exchanging nutrients and electrons for hydrogen production. The consortial biohydrogen production depend upon constituent microbes, their interdependence, competition for resources, and other operating parameters while remediating a waste material in nature or bioreactor. The present review deals with development of granular algae-bacteria consortia, hydrogen yield in coculture, important enzymes and possible engineering for improved hydrogen production.

Automated summary

Microbes that recycle nutrients and detoxify ecosystems have the potential to meet future energy needs by producing biohydrogen through the collaboration of autotrophic and heterotrophic microbes. The production of hydrogen in granules involves mutual exchange of nutrients and electrons among microbes. The development of granular algae-bacteria consortia, optimization of hydrogen yield in coculture, investigation of key enzymes, and potential engineering strategies for enhanced hydrogen production are all important aspects discussed in this review.
