Shewanella vesiculosa sp. nov., a psychrotolerant bacterium isolated from an Antarctic coastal area.
Two strains of psychrotolerant bacteria, designated M7(T) and M5, isolated from Antarctic coastal marine environments were studied to determine their taxonomic position. The organisms comprised Gram-negative, rod-shaped, facultatively anaerobic cells that were motile by means of single polar flagella. Neither of the bacterial isolates had a requirement for Na(+). These two psychrotolerant strai...
متن کاملShewanella electrodiphila sp. nov., a psychrotolerant bacterium isolated from Mid-Atlantic Ridge deep-sea sediments.
Strains MAR441(T) and MAR445 were isolated from Mid-Atlantic Ridge sediments from a depth of 2734 m, and were found to belong to the genus Shewanella. The strains were rod-shaped, pigmented, non-motile and capable of anaerobic growth either by fermentation of carbohydrates or by anaerobic respiration. The strains utilized a variety of electron acceptors, including nitrate and ferric compounds, ...
متن کاملFlavobacterium antarcticum sp. nov., a novel psychrotolerant bacterium isolated from the Antarctic.
A yellow-pigmented, Gram-negative and aerobic bacterial strain, designated AT1026(T), was isolated from a terrestrial sample from the Antarctic. Results of 16S rRNA gene sequence analysis indicated that the Antarctic isolate belonged to the genus Flavobacterium, with the highest sequence similarity to Flavobacterium tegetincola (96.4 %). Cells were non-motile, non-gliding and psychrotolerant, w...
متن کاملPseudomonas guineae sp. nov., a novel psychrotolerant bacterium from an Antarctic environment.
Two Gram-negative, cold-adapted, aerobic bacteria, designated strains M8T and M6, were isolated from soil collected from the South Shetland Islands. The organisms were rod-shaped, catalase- and oxidase-positive and motile by means of polar flagella. These two psychrotolerant strains grew between -4 and 30 degrees C. 16S rRNA gene sequence analysis placed strains M8T and M6 within the genus Pseu...
متن کاملShewanella xiamenensis sp. nov., isolated from coastal sea sediment.
A Gram-negative, motile, rod-shaped bacterium, strain S4(T), was isolated from coastal sediment collected off Xiamen, China. The physiological and biochemical features of strain S4(T), determined using the API 20NE, API ZYM and Biolog GN2 systems, were similar to those of members of the genus Shewanella. Phylogenetic analyses based on 16S rRNA and gyrB gene sequences placed strain S4(T) in the ...
