Achromobacter panacis sp nov., isolated from rhizosphere of Panax ginseng

A novel strain DCY105(T) was isolated from soil collected from the rhizosphere of ginseng (Panax ginseng), in Gochang, Republic of Korea. Strain DCY105(T) is Gram-reaction-negative, white, non-motile, non-flagellate, rod-shaped and aerobic. The bacteria grow optimally at 30 degrees C, pH 6.5-7.0 and in the absence of NaCl. Phylogenetically, strain DCY105(T) is most closely related to Achromobacter marplatensis LMG 26219(T) (96.81%). The DNA G+C content of strain DCY105(T) was 64.4 mol%. Ubiquinone 8 was the major respiratory quinone, and phosphatidylethanolamine, phosphatidylglycerol, and diphosphatidylglycerol were amongst the major polar lipids. C-16:00, C(8:0)3OH and iso-C(17:0)3OH were identified as the major fatty acids present in DCY105(T). The results of physiological and biochemical tests allowed strain DCY105(T) to be differentiated phenotypically from other recognized species belonging to the genus Achromobacter. Therefore, it is suggested that the newly isolated organism represents a novel species, for which the name Achromobacter panacis sp. nov. is proposed with the type strain designated as DCY105(T) (=CCTCCAB 2015193(T) =KCTC 42751(T)).
