Research progress of hydrogen production by photosynthetic bacteria

Hydrogen is the most commonly used clean energy with high energy content and clean combustion characteristics. There are many ways to produce hydrogen. Biological hydrogen production is the cleanest method compared with traditional physical and chemical processes. However, the hydrogen production quantity and hydrogen production rate of large-scale biological hydrogen production are often limited by various factors such as the environment. In recent years, many studies have broken through the limitations of environmental factors such as microbial metabolism, energy and key enzymes of microbial hydrogen production. The efficiency of microbial hydrogen production was effectively improved. In this paper, the main methods of biological hydrogen production are summarized and the influencing factors of hydrogen production by photosynthetic bacteria and the research progress of effective promotion of hydrogen production are discussed in detail. In order to provide a reference for the in-depth research in the field of biological hydrogen production and contribute to industrial large-scale hydrogen production to reduce environmental pollution.
