Regulators of nonsulfur purple phototrophic bacteria and the
The extreme metabolic versatility of these organisms allows them to grow by anoxygenic photosynthesis, aerobic or anaerobic respiration and fermentation. During photoautotrophic and chemoautotrophic growth, NSP bacteria can grow using H 2 as an electron donor while obtaining fixed carbon through the reduction CO 2 using the CBB–Benson

Hydrogen from wastewater by photocatalytic and
Dec 18, 2020 · Often, dark fermentation is coupled to photo-fermentation; the organic acids, by-products of dark fermentation, are then converted to hydrogen by the photosynthetic bacteria during photo-fermentation . An alternative bio-based technology to recover energy from wastewater is the use of microbial fuel cells (MFC).
Microalgae–bacteria symbiosis in microalgal growth and
Aug 31, 2018 · Microalgal-based hydrogen production represents a novel combination of fermentative and photolytic hydrogen-generating processes. It is well known that hydrogen production by microalgae depends on a hydrogenase enzyme activity that is highly sensitive to oxygen (Melis and Happe 2001). Therefore, strict anaerobic conditions are necessary for

Studies on Hydrogen Production by Photosynthetic Bacteria
In order to establish the sequential hydrogen production from waste starch using a hyperthermophile, Pyrococcus furiosus, and a photosynthetic bacterium, basic studies were done. P. furiosus produced hydrogen and acetate by anaerobic fermentation at 90°C. A photosynthetic bacterium, Rhodobacter sphaeroides RV, was able to produce hydrogen from acetate under anaerobic and light conditions at

Recent Achievements in Microalgal Photobiological Hydrogen
It is well known that over the last 60 years the trend of long-lived greenhouse gas emissions have shown a strong acceleration. There is an increasing concern and a mounting opposition by public opinion to continue with the use of fossil energy. Western countries are presently involved in a so-called energy transition with the objective of abandoning fossil energy for renewable sources. In
