Abstract

A novel stalked bacterium, designated strain T3-B7, was isolated from sediment of Taihu Lake, Jiangsu Province, China, and its taxonomy was studied by using a polyphasic approach. Cell morphology, physiological and biochemical properties, and polar lipids indicated that strain T3-B7 represented a member of the genus . Based on 16S rRNA gene sequence similarity analysis, strain T3-B7 was found to be phylogenetically related to DSM 4723 (98·5 %) and DSM 4724 (95·0 %), but could be differentiated from these two species on the basis of the number and position of prosthecae, assimilation of sugars, nitrate reduction and tolerance to NaCl. Levels of DNA–DNA relatedness of strain T3-B7 to DSM 4723 and DSM 4724 were 37·1 and 18·0 %, respectively. The G+C content of strain T3-B7 was 59 mol% ( ). It is concluded that strain T3-B7 represents a novel species of the genus , for which the name of sp. nov. is proposed. The type strain is T3-B7 (=AS 1.3431=JCM 12463).
