A new species of the genus Cohnella, named Cohnella mopanensis, was isolated from a forest soil sample collected from Mopan Mountain National Forest Park in Yunnan Province, China. This strain shows distinctive physiological and biochemical characteristics, and is genetically different from known strains.
A Gram-stain-negative, aerobic, rod-shaped bacteria strain, named YIM B01951(T), was isolated from a forest soil sample collected from Mopan Mountain National Forest Park, Xinping City, Yunnan Province, southwest PR China (101 degrees 58 ' 06 N, 23 degrees 03 ' 02 E). Growth occurred at 15-40 degrees C (optimum, 30 degrees C), pH 5.0-8.0 (optimum, pH 6.5) and with up to <= 3.0% (w/v) NaCl on Nutrient Agar plates. The results of 16S rRNA gene sequence similarity analysis showed that strain YIM B01951(T) was closely related to the type strain of Cohnella arctica M9-62(T) (96.5%) and Cohnella lupini RLAHU4B(T) (96.3%). YIM B01951(T) contains anteiso-C-15:0 and iso-C-16:0 as the major cellular fatty acids; the main polar lipids are diphosphatidylglycerol (DPG), phosphatidylglycerol (PG), phosphatidylethanolamine (PE), lysylphosphatidylglycerol (PGL) and five aminophospholipids (APL). The MK-7 is the major respiratory quinone and the DNA G + C content is 49.2 mol%. Based on these phenotypic, chemotaxonomic and phylogenetic analyses, strain YIM B01951(T) is considered to be a novel species of the genus Cohnella, and named Cohnella mopanensis sp. nov. The type strain is YIM B01951(T) (= NBRC 115331(T) = KCTC 43370(T)).
