Psychroflexus tropicus sp. nov., an obligately halophilic Cytophaga-Flavobacterium-Bacteroides group bacterium from an Hawaiian hypersaline lake
A Gram-negative bacterium designated LA1T was isolated from water collected in hypersaline Lake Laysan on Laysan Island in the Northwestern Hawaiian Islands. Cells occurred singly as fine rods to short filaments. Growth in 50% strength marine broth occurred optimally when the medium contained 7.5-10...
