Antonie Van Leeuwenhoek, 1994
Purple non-sulfur phototrophic bacteria, exemplified by Rhodobacter capsulatus and Rhodobacter sphaeroides, exhibit a remarkable versatility in their anaerobic metabolism. In these bacteria the photosynthetic apparatus, enzymes involved in CO2 fixation and pathways of anaerobic respiration are all induced upon a reduction in oxygen tension.

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.

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 ...

Energy Conversion and Management, 1995
Abstract We screened several strains which exhibited significant photoorganotrophic growth on a chemically defined synthetic medium containing alcohols. Samples from sewage, rice fields, or other places were inoculated under anaerobic-light conditions at 30°C.

On cytochrome oxidase as the terminal oxidase of dark respiration of non-sulfur purple bacteria
Biochimica et Biophysica Acta (BBA) - Biophysics including Photosynthesis, 1965Abstract Spectroscopic evidence was obtained for the occurrence of a cytochrome of a type in a particulate preparation of dark-aerobically-grown cells of Rhodopseudomonas spheroides. The particulate preparation catalyzed the aerobic oxidation of reduced bovine cytochrome c, yeast cytochrome c and cytochrome c2.

Reviews in Environmental Science and Bio/Technology, 2021
Polyhydroxyalkanoates (PHA) are a group of biopolymers produced naturally by microorganisms with properties similar to various petroleum-based plastics. However, to date their commercial production has remained uncompetitive due to substrate, sterilization, aeration and processing costs.
