Abstract

Strain BS12T, a Gram-negative motile bacterium, was isolated from soil in South Korea and characterized to determine its taxonomic position. Phylogenetic analyses based on the 16S rRNA gene sequence revealed that the strain belonged to the family Alcaligenaceae in the class Betaproteobacteria. The highest degree of sequence similarities of strain BS12T were found with Pigmentiphaga litoralis JSM 061001T (98.3%), Pigmentiphaga daeguensis K110T (98.2%), and Pigmentiphaga kullae K24T (98.1%). Chemotaxonomic data revealed that strain BS12T possessed ubiquinone-8, which is common in the family Alcaligenaceae, and the predominant fatty acids were C16:0, C17:0 cyclo, summed feature 3 (C16:1 ω6c/ω7c), and summed feature 8 (C18:1 ω6c/ω7c). The major polar lipids of strain BS12T were phosphatidylethanolamine and phosphatidylglycerol. Based on these data, BS12T (=KCTC 23577T =JCM 17666T =KEMB 9004-082T) should be classified as a type strain of a novel species, for which the name Pigmentiphaga soli sp. nov. is proposed.
