Description and genome-wide analysis of Profundicola chukchiensis gen. nov., sp. nov., marine bacteria isolated from bottom sediments of the Chukchi Sea
Two Gram-negative, aerobic halophilic non-motile strains designated KMM 9713 and KMM 9724(T) were isolated from the bottom sediments sampled from the Chukchi Sea in the Arctic Ocean, Russia. The novel strains grew in 0.5−5% NaCl, at 7−42°C, and pH 5.5−10.5. Phylogenetic analyses based on 16S rRNA ge...
