Abstract
A psychropiezophilic bacterium, strain 2825T (=LMG 21260T =JCM 11437T), isolated from deep Atlantic sediments at a depth of 2770 m and a temperature of 2 °C, was found by polyphasic analysis to represent a novel species of the genus Psychromonas, Psychromonas profunda sp. nov. It is a strict psychrophile and a moderate piezophile, whose degree of piezophily is increased markedly when the temperature is raised to 10 °C. The piezophily of P. profunda is intermediate between that of the type species, Psychromonas antarctica, which is not piezophilic, and that of Psychromonas kaikoae, which is an obligate piezophile.Keywords
