Abstract:
A Gram-stain-negative bacterium, designated SP-35 T , was isolated from compost and was subjected to a taxonomic study. This isolate was short-rod-shaped and non-spore-forming. Phylogenetic analysis based on 16S rRNA sequence comparison indicated the isolate was related to the genus Comamonas . 16S rRNA gene sequence analysis showed that its closest neighbours were the type strains Comamonas odontotermitis Dant 3-8 T (96.8 % similarity), Comamonas testosteroni DSM 50244 T (96.5 %), Comamonas guangdongensis CY01 T (95.9 %) and Comamonas composti YY287 T (95.6 %). Using phylogenetic analysis, DNA–DNA hybridization, fatty acid composition data and a range of physiological and biochemical characteristics we could clearly distinguish strain SP-35 T from type strains of the genus Comamonas . The genomic DNA G+C content of strain SP-35 T was 63.1 mol%. The predominant cellular fatty acids were C 16 : 0 , C 17 : 0 cyclo, summed feature 3 (C 16 : 1 ω6 c and/or C 16 : 1 ω7 c ) and summed feature 8 (C 18 : 1 ω6 c and/or C 18 : 1 ω7 c ). The major polar lipids were diphosphatidylglycerol, phosphatidylethanolamine and phosphatidlyglycerol. Differences in phenotypic and phylogenetic characteristics support the classification of strain SP-35 T as a representative of a novel species in the genus Comamonas , for which the name Comamonas serinivorans sp. nov. is proposed. The type strain is SP-35 T ( = DSM 26136 T = JCM 18194 T ).
