Mixed catalyst-bacterial system gives photosynthesis a run
Jun 10, 2016 · Inorganic catalysts combined with carbon-fixing bacteria could produce biofuels. Shalini Saxena - 6/10/2016, 10:25 AM. Bedford, MA. Most life depends on the Sun. Through photosynthesis, plants and
Photosynthetic bacteria improved hydrogen yield of combined
Aug 20, 2019 · In combined dark- and photo-fermentation process, addition of photosynthetic bacteria increased pH, decreased ORP and VFAs, and finally increased hydrogen yield. A positive or syntrophic relationship existed between the dark- and photo-fermentative bacteria, resulting in higher hydrogen yield, when compared with those achieved using single types of bacteria.

production of industrial CO 2. In the gas separation process, it is possible to capture the residual gas, carbon dioxide CO 2. After a few additional downstream purification washing steps the carbon dioxide, may be utilized: in crop greenhouses to accelerate the photosynthesis, in the production of algae or other biomass in a photobioreactor,
Hydrogen Production by the Photosynthetic Bacterium
Continuous photosynthetic production of hydrogen by Rhodospirillum rubrum in batch cultures was observed up to 80 days with the hydrogen donor, pure lactate or lactic acid-containing wastes, supplied periodically. Hydrogen was produced at an average rate of 6 ml/h per g (dry weight) of cells with whey as a hydrogen donor.
Microbial production of hydrogen: an overview
Production of hydrogen by anaerobes, facultative anaerobes, aerobes, methylotrophs, and photosynthetic bacteria is possible. Anaerobic Clostridia are potential producers and immobilized C. butyricum produces 2 mol H2/mol glucose at 50% efficiency. Spontaneous production of H2 from formate and glucose by immobilized Escherichia coli showed 100% and 60% efficiencies, respectively.
Polyhydroxyalkanoate (PHA) Production Using Volatile Fatty
Sep 04, 2020 · Waste paper as a resource for polyhydroxyalkanoate (PHA) production through anaerobic digestion is a low-cost strategy to produce bioplastic. In this study, volatile fatty acids (VFAs) produced from waste paper, one of the significant constituents of municipal solid waste, was utilized as a feedstock for polyhydroxyalkanoate (PHA) production. PHA production from synthetic VFAs by Cupriavidus

Recycling Methane Could Be the Key to Nationwide Renewable
Bromels: Methane, if I can pop in with the science on this for a second, methane, CH4, carbon, and hydrogen. But yes, believe it is the second most potent greenhouse gas behind water vapor, that you can release, at least of the gases that are generally released into the atmosphere.
Isolation of Industrial Important Bioactive Compounds from
Feb 10, 2021 · They possess chlorophyll a and the photosynthetic systems; Photosystem II (PS II) and Photosystem I (PS I), that enables them to perform photosynthesis by absorbing solar energy and converting water into hydrogen and oxygen [214,215]. Biophotolysis can be divided into two; direct and indirect pathways.
Researchers engineer photosynthetic bacteria to produce hydrogen
May 07, 2020 · Researchers engineer photosynthetic bacteria to produce hydrogen and hydrogen production stops again. Combined, these things ensure that the window for hydrogen production is very brief.
Fermentative hydrogen production using pretreated microalgal
Feb 14, 2018 · Microalgae are simple chlorophyll containing organisms, they have high photosynthetic efficiency and can synthesize and accumulate large quantities of carbohydrate biomass. They can be cultivated in fresh water, seawater and wastewater. They have been used as feedstock for producing biodiesel, bioethanol and biogas. The production of these biofuels can be integrated with CO2 mitigation
