molecular microbial diversity of a soil sample and detection of ammonia oxidizers from cape evans, mcmurdo dry valley, antarctica.the aim of our study was to estimate the uncultured eubacterial diversity of a soil sample collected below a dead seal, cape evans, mcmurdo, antarctica by an ssu rdna gene library approach. our study by sequencing of clones from ssu rdna gene library approach revealed high diversity in the soil sample from antarctica. more than 50% of clones showed homology to cytophaga-flavobacterium-bacteroides group; sequences also belonged to alpha, beta, gamma proteobacteria, thermus-deinococcus and high gc ...200716517136
aequorivita capsosiphonis sp. nov., isolated from the green alga capsosiphon fulvescens, and emended description of the genus aequorivita.a marine bacterial strain, designated a71(t), was isolated from marine algae collected from the south sea, republic of korea. phylogenetic analysis based on 16s rrna gene sequences indicated that strain a71(t) belonged to the family flavobacteriaceae and was closely related to aequorivita antarctica sw49(t) (96.5 % sequence similarity). cells of strain a71(t) were gram-negative, aerobic, oxidase-negative, catalase-positive, yellow/orange-pigmented and non-motile. the major fatty acids were iso-c ...200919329596
aequorivita gen. nov., a member of the family flavobacteriaceae isolated from terrestrial and marine antarctic habitats.several strains isolated from antarctic winter sea water, sea-ice algal assemblages and quartz stone subliths were found to belong to a novel 16s rdna sequence cluster within the family flavobacteriaceae (cytophaga-flavobacterium-bacteroides division). the strains were gram-negative, non-motile, psychrotolerant, strictly aerobic, chemoheterotrophic rod-shaped cells that contained orange or yellow carotenoid pigments and required yeast extract when grown in defined mineral-salts media. the requir ...200212361255
