Pusillimonas ginsengisoli sp. nov., isolated from soil of a ginseng field.
Two novel strains of Gram-negative, non-sporulating, short rod-shaped, motile bacteria, designated DCY25T and DCY28, were isolated from soil of a ginseng field in South Korea and characterized in order to determine their taxonomic position. 16S rRNA gene sequence analysis showed that strains DCY25T and DCY28 belonged to the Betaproteobacteria, the highest sequence similarities being found with Pusillimonas noertemannii BN9T (96.9%), Bordetella trematum DSM 11334(T) (95.9%), Achromobacter denitrificans DSM 30026T (95.9%), Achromobacter insolitus LMG 6003T (95.8%) and Pigmentiphaga kullae K24T (95.5%). Chemotaxonomic data revealed that both strains DCY25T and DCY28 possessed ubiquinone Q-8. Fatty acid analysis of strain DCY25T demonstrated the presence of 19:0 cyclo omega8c (22.8%) and 16:0 (16.6%). The polar lipid profiles of strains DCY25T and DCY28 included phosphatidylethanolamine, phosphatidylglycerol, two unknown aminolipids and diphosphatidylglycerol. The G+C contents of strains DCY25T and DCY28 were 57.3 and 57.2 mol%, respectively. DNA-DNA relatedness values, biochemical and physiological characteristics strongly supported the genotypic and phenotypic differentiation of strains DCY25T and DCY28 from Pusillimonas noertemannii. Therefore, strains DCY25T and DCY28 should be classified in a novel species, for which the name Pusillimonas ginsengisoli sp. nov. is proposed. The type strain is DCY25T (=KCTC 22046T =JCM 14767T); strain DCY28 (=KCTC 22047=JCM 14768) is a reference strain.
