“…For the PNS organism to grow and produce hydrogen, photo heterotrophy is generally preferred. This photo fermentation is carried out via the catalytic action of two enzymes involving hydrogenase and nitrogenase via the Tricarboxylic Acid (TCA) cycle [112,132]. The production of hydrogen gas by PNS bacteria is possible as a result of one of the important enzymes: Nitrogenase.…”

More than 80% of the energy from fossil fuels is utilized in homes and industries. Increased use of fossil fuels not only depletes them but also contributes to global warming. By 2050, the usage of fossil fuels will be approximately lower than 80% than it is today. There is no yearly variation in the amount of CO2 in the atmosphere due to soil and land plants. Therefore, an alternative source of energy is required to overcome these problems. Biohydrogen is considered to be a renewable source of energy, which is useful for electricity generation rather than relying on harmful fossil fuels. Hydrogen can be produced from a variety of sources and technologies and has numerous applications including electricity generation, being a clean energy carrier, and as an alternative fuel. In this review, a detailed elaboration about different kinds of sources involved in biohydrogen production, various biohydrogen production routes, and their applications in electricity generation is provided.

“…One of the PSB groups is Purple Non-Sulfur Bacteria (PNSB), prokaryotes that have versatile anaerobic metabolism as photoautotrophic, photoheterotrophic, chemoautotrophic, and chemoheterotrophic, depending on the presence of nutrients, O2 concentration, and light intensity. This metabolic flexibility recommends it for biotechnological applications such as environmental bioremediation, bioenergy production, biopolymers such as polyhydroxybutyrate (PHB) as an alternative to petroleum-based plastics, and in agriculture as a biofertilizer [17][18][19][20] added, PNSB is a gramnegative prokaryote, facultative anoxygenic phototroph, belonging to the class Alphaproteobacteria and includes several genera in the orders Rhodobacterales, Rhodospirales, and Rhizobiales.…”

“…These bacteria can grow in both aerobic and anaerobic conditions and can use organic or inorganic materials as electron donors for biological CO2 and N2 fixation [22,23] can live on the leaf surface (phyllosphere) and increase the activity of other phyllosphere microbial species. Around the roots increases the metabolic activity of other beneficial bacteria to promote growth and increase nutrient absorption by the roots [20].…”

“…Photosynthesis in PNSB occurs in the intracytoplasmic membrane which consists of photosystems, transport proteins, cytochrome complexes, and ATP synthase proteins. The photosystem transfers energy to the reaction center and initiates cyclic electron transfer [20].…”

“…Photosynthesis biosynthesis is mainly controlled by O2 (bacteriochlorophyll synthesis is suppressed during aerobic conditions) and light, at low light intensity, photosystem biosynthesis increases to collect more light energy, and vice versa [24][25][26]. Changes in sunlight intensity and temperature greatly influence PNSB growth and hydrogen production [20].…”

The research was conducted to determine the effect of the application of PNSB on the growth and yield of komak beans under shade. The experiment was arranged in a Split Plot Design, consisting of two factors, namely shade as the Main Plot and concentration of PNSB as Sub-Plots. The shade consists of two levels (no shade and 50% shade). The PNSB concentration consists of three levels (0; 5; and 10 mL L-1). Each treatment was carried out with four replications. Data were analyzed using analysis of variance and continued with Duncan's Multiple Range Test at a 5% significance level. The results showed that the effect of shade was significantly different on stem diameter at 70 DAP, chlorophyll content (a, b, and total), and the number of dry seeds, very significantly different to stem diameter at 105 DAP, dry pod weight, number of dry pods, dry seed weight, and light intensity. 50% shade reduces the yield component even if PNSB is provided. The effect of PNSB was not significantly different on all variables, except for the number of leaves at 35 DAP and total N content. Application of PNSB 10 mL L-1 increased the number of leaves aged 35 DAP and the total N content, both without shade and with shade, increased total chlorophyll content with 50% shade, but decreased without shade.
