THE FINE STRUCTURE OF RHODOSPIRILLUM RUBRUM [PDF]

The Journal of Cell Biology, 1963
The fine structure of Rhodospirillum rubrum grown under a series of defined conditions has been examined in thin sections prepared by the methods of Ryter and Kellenberger. In cells grown anaerobically at different light intensities, the abundance of 500 A membrane-bounded vesicles in the cytoplasm is inversely related to light intensity, and directly ...

Poly(3-hydroxybutyrate-co-3-hydroxyvalerate) Production by Rhodospirillum rubrum Using a Two-Step Culture Strategy

Journal of Chemistry, 2019
Polyhydroxyalkanoates (PHAs) are microbially synthesized biopolyesters which have attracted great attentions as a new biological material, potential alternative to traditional fossil fuel-based plastic due to their biodegradability and biocompatibility ...

The Role of Bacteria and Factors Affecting the Decomposition of Pollutants in the Biofilter Reactor: A Review

Applied Environmental Research, 2023
The findings showed that several types of bacteria can help biodegrade organic pollutants, such as Comamonadacea, which can biodegrade volatile fatty acids and aromatic compounds. Proteobacteria, Bacteroidetes, and Actinobacteria can biodegrade ammonium.

OBSERVATIONS ON THE STRUCTURE OF RHODOSPIRILLUM RUBRUM [PDF]

The Journal of Cell Biology, 1965
Sections of Rhodospirillum rubrum cells from cultures of different ages have been examined to obtain information on the development of chromatophores in this organism. Cells from the 12-hour cultures studied contain neither distinct invaginations of the cytoplasmic membrane nor distinct chromatophores.

Small molecule carbon source promoting dairy wastewater treatment of Rhodospirillum rubrum by co-metabolism and the establishment of multivariate nonlinear equation

Water Science and Technology, 2022
Rhodospirillum rubrum water treatment technology could recycle bio-resource. However, the inability to degrade macromolecular organics limited its wide application. This paper discussed the feasibility of small molecular carbon source promoting R. rubrum

Improvement of Biocatalytic Properties and Cytotoxic Activity of L-Asparaginase from Rhodospirillum rubrum by Conjugation with Chitosan-Based Cationic Polyelectrolytes

Pharmaceuticals, 2022
L-asparaginases (L-ASNases, EC 3.5.1.1) are a family of enzymes that are widely used for the treatment of lymphoblastic leukemias. L-ASNase from Rhodospirillum rubrum (RrA) has a low molecular weight, low glutaminase activity, and low immunogenicity ...

Metabolic Regulation as a Consequence of Anaerobic 5-Methylthioadenosine Recycling in Rhodospirillum rubrum

mBio, 2016
Rhodospirillum rubrum possesses a novel oxygen-independent, aerobic methionine salvage pathway (MSP) for recycling methionine from 5-methylthioadenosine (MTA), the MTA-isoprenoid shunt.

Strategies and mechanisms of precision genome engineering: From gene editing to genome writing

iMetaOmics, EarlyView.
In this review, we examined the progression of genome manipulation from stochastic nuclease‐mediated cutting toward precise editing and programmable genome writing. We discussed tools like multi‐kilobase RNA‐guided integrators and Artificial Intelligence (AI)‐designed effectors and showed how these advances enable researchers to treat genomes as ...
