A Gram-negative, short rod-shaped bacterial strain, YC06271T, was isolated from the vermicompost (VC) collected at Masan, Korea and its taxonomic position was investigated by a polyphasic taxonomic approach. Strain YC06271T grew optimally at 28-30 degrees C and at pH 7.0-9.0. The 16S rRNA gene sequence of strain YC06271T was most closely related to members of the genera Bordetella (96.4-95.8 %), Achromobacter (96.0-95.7 %), Alcaligenes (96.0-94.2 %), Pusillimonas noertemannii (95.9 %), Pigmentiphaga (95.8-95.5 %) and less than 95.5 % similarity with the members of the other genera of the family Alcaligenaceae. Strain YC06271T contained ubiquinone-8 (Q-8) as the major respiratory quinone system and putrescine as the major polyamine. The major fatty acids of strain YC06271T were C16:1omega7c and/or C15:0 iso 2-OH and C16:0. The major polar lipids were phosphatidylglycerol and phosphatidylethanolamine. The G+C content of the genomic DNA was 55.4 mol%. Phylogenetic analysis, biochemical, chemotaxonomic and phenotypic characteristics strongly supported the differentiation of strain YC06271T from the validly published genera of the family Alcaligenaceae. Therefore, it is proposed that strain YC06271T represents a novel species within a novel genus, with the name Eiseniicola composti gen. nov., sp. nov. The type strain is YC06271T (= KCTC 22250T = DSM 21045T).
