Abstract

Moderately halophilic strain DT-C was isolated from the mud of the Mariana Trench. Cells of the organism were rod-shaped (3 m x 1.5 m) with polar flagella. Growth occurred in a NaCl concentration of about 0.1-15% (optimal: 1-5%), at pH of 5-10, and at temperatures ranging from 4-48 °C (optimal: 35 °C). The results of 16S rDNA analysis and DNA-DNA hybridization analyses showed that DT-C was closely related to Idiomarina zobellii which is also isolated from the deep sea.
