“…However, a recent study demonstrated that Chlamydomonas reinhardtii mutants obtained via atmospheric and room temperature plasma (ARTP) showed a lighter green coloration, compared to wild types, indicative of lower chlorophyll content. The lower chlorophyll content is associated with better photosynthetic performance (probably due to the improved light transmit-tance and the consequent increased solar energy conversion efficiency), as confirmed by transcriptomic analyses, with consequent benefits in hydrogen production [40].…”

The need to safeguard our planet by reducing carbon dioxide emissions has led to a significant development of research in the field of alternative energy sources. Hydrogen has proved to be the most promising molecule, as a fuel, due to its low environmental impact. Even if various methods already exist for producing hydrogen, most of them are not sustainable. Thus, research focuses on the biological sector, studying microalgae, and other microorganisms’ ability to produce this precious molecule in a natural way. In this review, we provide a description of the biochemical and molecular processes for the production of biohydrogen and give a general overview of one of the most interesting technologies in which hydrogen finds application for electricity production: fuel cells.

“…The other method is RNAi mediated knockout of LHCs or chlorophyll synthesis genes to produce maximized H 2 yield (Oey et al, 2016). Polle et al, 2003;Melis and Chen, 2005;Xu et al, 2011;Mitra et al, 2012;Oey et al, 2016;Wang et al, 2017Wang et al, , 2018Li et al, 2018;Ban et al, 2019;Yang et al, 2019 Although there has been a breakthrough in the research of biohydrogen production from microalgae, it is still too early for large-scale application. Under general circumstances, the expression level of the biohydrogen production-related gene HydA in microalgae is very low, and only under the induction of an anaerobic environment can it be expressed in large quantities.…”

The non-renewable nature of fossil energy and the environmental pollution caused by its use, such as haze, make it very urgent to develop clean and efficient renewable energy. By using microalgae biomass as an alternative raw material energy sources like biohydrogen, methane can be produced through fermentation and photosynthesis. Unlike solar energy, which has the disadvantages of low energy density, instability and difficulty in storage, biohydrogen and biogas are one of the novel ideal energy sources at present. The utilization of microalgae has various attractive prospects in their production due to its cost-effectiveness, renewable biomass and ease of scaling-up technology. This paper discusses the latest microalgae biomass biohydrogen and biogas production technology including integrated biorefinery systems, co-production or mixed production techniques and puts forward the key problems to be solved in the development of microalgae biohydrogen production technology.

“…Light capture is the first step in the production of hydrogen under light conditions, and reducing the size of the antenna can improve the light‐harvesting efficiency, which is crucial for the enhancement and optimization of light harvesting. By shortening the light harvesting antenna of the photosystem, the light utilization efficiency was increased with hydrogen production increasing . Many genes and mutants regulating the size of light‐harvesting antenna in green algae have been identified through high‐throughput screening.…”

Microalgae, as facultative aerobic organisms, convert solar energy to produce biohydrogen under anaerobic condition. Biohydrogen is a kind of ideal clean and renewable energy source with great commercial potential. Many endeavors have been focused on improving the biohydrogen yields by various means. Here, the research history of hydrogen production by microalgae (including cyanobacteria and green algae), the characteristics of nitrogenase and hydrogenase, the mechanisms of hydrogen production, the technological progress, and the application of enzymatic, genetic, and metabolic engineering methods to improve hydrogen production by microalgae are reviewed. In addition, the regulation of anaerobic metabolisms of Chlamydomonas reinhardtii after the disruption of key enzymes functioning in the fermentative pathways is discussed. Finally, the main challenges and obstacles facing the more efficient production and commercialization of hydrogen production from microalgae in the future are proposed.
