Production of Polyhydroxybutyrate by Pure and Mixed Cultures of Purple Non-Sulfur Bacteria: A Review
Journal of Biotechnology, 2020Purple non-sulfur bacteria (PNSB), most commonly called photobacteria, are a group of photoheterotrophic bacteria well known for their ability to produce hydrogen while degrading several carbon substrates, such as organic acids and carbohydrates, as well as organic matter in wastewater and effluents from other processes, such as dark fermentation ...

Polyhydroxyalkanoates From Organic Waste Streams Using Purple Non-Sulfur Bacteria
Bioresource Technology, 2021Many microorganisms can produce intracellular and extracellular biopolymers, such as polyhydroxyalkanoates (PHA). Despite PHA's benefits, their widespread at the industrial level has not occurred due mainly to high production costs. PHA production under a biorefinery scheme is proposed to improve its economic viability.

Recent progress in the use of purple non-sulfur bacteria as probiotics in aquaculture
World Journal of Microbiology and Biotechnology, 2023The use of probiotics in aquaculture is widely recognized as an ecological and cost-effective approach to raising healthy, pathogen-tolerant aquatic animals, including fish and shrimp. In particular for shrimp, probiotics are viewed as a promising countermeasure to the recent severe damage to the shrimp industry by bacterial and viral pathogens. Purple

[Morphological differentiation in non-sulfur purple bacteria].
Mikrobiologiia, 1977Cell differentiation in non-sulphur purple bacteria is complicated, as compared to binary fission, during bud formation with production of hyphae and special resting cells of the exospore type, and can be demonstrated in the folowing series of microorganisms: Rhodopseudomonas sulfidophila leads to Rh. capsulata leads to Rh.

Integration of Purple Non-Sulfur Bacteria Into the Starch-Hydrolyzing Consortium
International Journal of Hydrogen Energy, 2014Abstract Purple non-sulfur bacteria Rhodobacter sphaeroides N7 was integrated into the heterotrophic starch-hydrolyzing consortium containing Clostridium butyricum as the main component. The resulting light-dependent consortium with Bchl ∼9 μg/ml was maintained during 12 months of regular transfers.

Photosynthetic fuel cell using purple non-sulfur bacteria
2012 International Symposium on Optomechatronic Technologies (ISOT 2012), 2012A photosynthetic fuel cell by bacteria has attracted features for a new energy by photosynthetic bacteria. Conventional methods requires for a mediator. It has a drawback because of light deterioration material. This paper is focused to develop a mediatorless fuel cell by photosynthetic bacteria with high efficiency.

Regulation of CO2 fixation in non-sulfur purple photosynthetic bacteria
2005Our laboratory studies the regulation of CO2 fixation in phototrophic micro-organisms. The expression of genes encoding enzymes responsible for assimilating CO2 is primarily regulated by a LysR-type transcriptional activator, CbbR, that functions by binding specific sites in the promoter region of both the cbb I and cbb II CO2 fixation operons under ...
