Phototrophic growth on n-fatty acids by members of the family Rhodospirillaceae
Systematic and Applied Microbiology, 1987Summary Thirty one strains, representing 15 species of the family Rhodospirillaceae, were tested for their ability to grow phototrophically on n-fatty acids with chain lengths of 5 to 18 carbon atoms. Twenty seven strains were able to utilize the entire range tested, while 3 others were only able to grow on a more limited range.

Evolution of the Rhodospirillaceae and Mitochondria: A View Based on Sequence Data
1981New sequence data from several protein families and from 5S ribosomal RNA confirm and elaborate our description of the phylogenetic connections between a variety of bacteria and the eukaryotes (1,2). Probably the first organisms were nonphotosynthetic anaerobic prokaryotes, which were followed soon by photosynthetic anaerobes.

As a class of multifunctional biocatalysts, halohydrin dehalogenases are of great interest for the synthesis of chiral β-substituted alcohols and epoxides. There are less than 40 halohydrin dehalogenases with relatively clear catalytic functions, and most of them do not meet the requirements of scientific research and practical applications. Therefore,

A novel Gram-negative, vibrio-shaped, motile bacterium, designated strain AK4T, was isolated from a sediment sample collected from a solar saltern at Kakinada, Andhra Pradesh, India. Strain AK4T was positive for oxidase, urease and DNase activities but negative for gelatinase, catalase, ornithine decarboxylase, lysine decarboxylase, nitrate reduction ...

Long-term preservation of some Rhodospirillaceae by freeze-drying
Journal of Microbiological Methods, 1988Abstract Lyophilization of phototropically grown cultures is difficult as it is essential to maintain strict anaerobic conditions or to avoid the exposure of the cultures to light. During a systematic investigation it was observed that several species of Rhodospirillaceae are able to grow heterotrophically in darkness on organic media and are not ...

The ability to use adenosine 5′-phosphosulfate (APS) or 3′-phosphoadenosine 5′-phosphosulfate (PAPS) as the substrate for the initial reductive step in sulfate assimilation has been tested in most of the known Rhodospirillaceae species and in some chemotrophic bacteria.

A novel, Gram-staining-negative, non-pigmented, rod-shaped, strictly aerobic, extremely halophilic bacterium, designated strain IA16T, was isolated from the mud of the hypersaline Lake Aran-Bidgol, in Iran. Cells of strain IA16T were not motile. Growth occurred with 2.5–5.2 M NaCl (optimum 3.4 M), at pH 6.0–8.0 (optimum pH 7.0) and at 30–50 °C (optimum

A pyrophosphate-dependent fructose-6-phosphate phosphotransferase from the photosynthetic bacterium Rhodospirillum rubrum was partially purified and characterized in respect to kinetic and regulatory properties. The enzyme had a molecular weight of about 95 000 dalton and required Mg2+-ions for catalysis and maintenance of activity.
