ABSTRACT
A slightly beige-pigmented, Gram-stain-negative, rod-shaped bacterium, strain IMT-318T, was isolated from soil in a field located in Malvern, Alabama, USA. Phylogenetic analysis based on the 16S rRNA gene placed the strain within the genus Pigmentiphaga with highest 16S rRNA gene sequence similarity of 98.74â% and 98.67â% to the type strains of Pigmentiphaga kullae and Pigmentiphaga daeguensis, respectively. Sequence similarities to all other species of the genus were below 98.0â%. Results of the chemotaxonomic analysis, however, showed clear similarities to the genus Pigmentiphaga. The main cellular fatty acids of the strain were C16ââ0, C18ââ1 ω7c, C17ââ0 cyclo and C19ââ0 cyclo ω8c. The major quinone was ubiquinone Q-8. The polar lipid profile was composed of phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol and an unidentified aminophospholipid. In the polyamine pattern, putrescine and 2-hydroxyputrescine were predominant. The diamino acid of the peptidoglycan was meso-diaminopimelic acid. Based on phylogenetic, chemotaxonomic and phenotypic analyses, we propose a new species of the genus Pigmentiphaga, with the name Pigmentiphaga humi sp. nov. and strain IMT-318T (=LMG 30658T=CIP 111626T=CCM 8859T) as the type strain.
