Two strains (JC83, JC84(T)) of obligately anaerobic, H2S-producing bacteria were isolated from estuarine sediment samples collected from Gangasagar, West Bengal, India. Cells were Gram-stain-negative, non-motile rods. Both strains were positive for oxidase, negative for catalase, hydrolysed casein, reduced nitrate and utilized citrate. Both strains grew(More)
Three strains (JA349(T), JA553(T), JA439) of phototrophic sulphur bacteria were isolated from marine habitats of India. 16S rRNA gene sequence of the three strains clustered phylogenetically with members of the genus Marichromatium of the family Chromatiaceae belonging to the class Gammaproteobacteria. All the strains shared highest sequence similarity with(More)
Four strains (JA310(T), JA531(T), JA447 and JA490) of red to reddish brown pigmented, rod-shaped, motile and budding phototrophic bacteria were isolated from soil and freshwater sediment samples from different geographical regions of India. All strains contained bacteriochlorophyll a and carotenoids of the spirilloxanthin series. The major cellular fatty(More)
A Gram-stain-positive, oxidase-negative, starch-hydrolysing, actinobacterium (strain JC82(T)) was isolated from a soda lake in Lonar, India. Based on 16S rRNA gene sequence similarity studies, strain JC82(T) belonged to the genus Georgenia and was most closely related to Georgenia muralis 1A-C(T) (96.8 %) and other members of the genus Georgenia (<96.5 %).(More)
A green phototrophic bacterium (strain JA737(T)), which was oval- to rod-shaped, Gram-negative and motile, was isolated from mud of a stream in the Western Ghats of India. Strain JA737(T) contained bacteriochlorophyll a, and the major carotenoid was neurosporene. The major quinone was Q-10 and the polar lipids were phosphatidylglycerol,(More)
A Gram-stain-negative, aerobic, pale orange, rod-shaped, non-motile bacterial strain, designated JC289T was isolated from a rhizosphere soil sample of the plant Oryza sativa (L.). 16S rRNA gene sequence analysis clearly allocated strain JC289T to the Flectobacillus cluster, showing highest sequence similarities to Flectobacillus roseus GFA-11T (99.5 %),(More)
A red-pigmented bacterium producing a metallic green sheen, designated strain JC333T, was isolated from a sand sample collected from Shivrajpur-Kachigad beach, Gujarat, India. Phylogenetic analyses based on the 16S rRNA gene sequence of strain JC333T showed highest sequence similarity to Zooshikella ganghwensis JC2044T (99.24 %) and less than 91.94 %(More)
The carotenoid, neurosporene, is of commercial importance due to its use as an antioxidant and UV-B radiation protector. It is usually obtained from fruits and vegetables. Although some bacterial mutants can accumulate neurosporene, these are unstable. A recently-isolated, natural and stable neurosporene accumulating, phototrophic purple non-sulfur(More)
Two strains (JA266(T) and JA333) of Gram-negative, rod-shaped, phototrophic, purple non-sulfur bacteria were isolated from a freshwater fish pond and an industrial effluent. Both strains were capable of phototrophic and chemotrophic growth. Bacteriochlorophyll a and carotenoids of the spirilloxanthin series were present as photosynthetic pigments. The major(More)
A rod-shaped, non-motile, Gram-stain-positive, catalase-positive, starch-hydrolysing strain, JC16(T), was isolated from a semi-arid tropical soil from India. Phylogenetic analysis based on 16S rRNA gene sequence showed that strain JC16(T) clustered with the type species of the genus Chryseomicrobium, Chryseomicrobium imtechense MW 10(T), a member of the(More)
