Glycerol dissimilation in Rhodopseudomonas sphaeroides [PDF]

open access: yesJournal of Bacteriology, 1975
Rhodopseudomonas sphaeroides followed a diauxic growth curve when grown on a malate-glycerol medium, the first phase of growth being supported by malate and the second by glycerol. A soluble glycerokinase and a particulate, pyridine nucleotide-independent glycerophosphate dehydrogenase, were induced by the presence of glycerol in the medium, but ...

Alternative microbial-based functional ingredient source for lycopene, beta-carotene, and polyunsaturated fatty acids

open access: yesHeliyon, 2023
The acquisition of carotenoids and polyunsaturated fatty acids (PUFAs) from plants and animals for use as functional ingredients raises concerns regarding productivity and cost; utilization of microorganisms as alternative sources is an option.

Pyruvate Carboxylase in Rhodopseudomonas spheroides [PDF]

open access: yesJournal of General Microbiology, 1969
SUMMARY: Unlike some other photosynthetic bacteria, Rhodopseudomonas spheroides directly carboxylates pyruvate in a reaction catalysed by a pyruvate carboxylase (E.C. 6·4.1·1). A partially purified preparation of the enzyme was acetylCoA-dependent. No phosphoenolpyruvate synthetase or phosphoenolpyruvate carboxylase activity was detected in extracts of

The Composition of Intestinal Microbiota From Collichthys lucidus and Its Interaction With Microbiota From Waters Along the Pearl River Estuary in China

open access: yesFrontiers in Environmental Science, 2021
By their nature and geographical location, estuaries shape different marine habitats via freshwater and seawater interactions. Thus, fish intestinal microbiota, as mediated by estuary habitat fluctuations, are fundamentally important but rarely studied ...

Bacteriophages of Rhodopseudomonas spheroides : Isolation and Characterization of a Rhodopseudomonas spheroides Bacteriophage [PDF]

open access: yesJournal of Virology, 1974
A DNA-containing bacteriophage, designated RS1, infecting Rhodopseudomonas spheroides 2.4.1, has been isolated from sewage. The buoyant density of RS1 in CsCl equilibrium centrifugation is 1.50 g/cm 3 , and the buoyant density of RS1 DNA is 1.706.

Hydrogen recycling by Rhodopseudomonas capsulata [PDF]

open access: yesFEBS Letters, 1977
capsdata evolves large quantities of molecular Hz via an energy-dependent nitrogenase activity when grown photoheterotrophically and supplied with certain amino acids, e.g., glutamate, as nitrogen source [ 1,2]. In addition, these bacteria are capable of utilizing Hz as a reductant for photoautotrophic growth.

Insights into the Effect of Carbon and Nitrogen Source on Hydrogen Production by Photosynthetic Bacteria

open access: yesChemical Engineering Transactions, 2014
Nowadays the growing interest in alternative fuels is motivated by several important considerations; since the most alternative fuels are not derived from finite fossil-fuel resources and generally produce fewer vehicle emissions that contribute to smog,
