Modern strategy of cyanobacterial biohydrogen production and current approaches toward its enhancement

Abstract

Cyanobacterial-based hydrogen production is an environmentally sustainable and economically feasible energy source, which appears to be a viable alternative for the future. The current condition of the research in cyanobacterial hydrogen production is described in the present study. Cyanobacteria are highly relevant and valuable as prospective hydrogen producers since they produce hydrogen from water due to solar energy conversion. However, hydrogen production is a complicated biotechnological process with the primary stumbling block; cyanobacteria have limited ability to generate hydrogen at present, a complex strategy for enhancing hydrogen production can improve the chances for the generation of hydrogen energy from cyanobacterial cells. This chapter summarizes current thoughts on cyanobacterial role in biohydrogen generation. It explains every step involved, scientific achievements, existing problems, and suggestions for future research goals and objectives in the process. © 2022 Elsevier Inc. All rights reserved.
