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°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_8:03OH and iso-C_17:03OH 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).
