Transfer of Defluvibacter lusatiensis to the genus Aquamicrobium as Aquamicrobium lusatiense comb. nov. and description of Aquamicrobium aerolatum sp. nov.
Analysis of the 16S rRNA gene sequences of the type strains of Aquamicrobium defluvii and Defluvibacter lusatiensis shows a similarity of 98.3 %. There is no evidence for clear phenotypic differences between these organisms that justifies assignment to different genera. Both have ubiquinone Q-10 as the dominant quinone type and very similar fatty acid profiles, with 18 : 1omega7c and 19 : 0 cyclo omega8c predominating. A proposal is made to transfer Defluvibacter lusatiensis to the genus Aquamicrobium as Aquamicrobium lusatiense comb. nov. (type strain S1(T) =CIP 106844(T) =DSM 11099(T)). Furthermore, a novel species within this genus, Aquamicrobium aerolatum sp. nov., is described, with strain Sa14(T) (=CCUG 57044(T) =DSM 21857(T)), isolated from air in a duck shed, as the type strain.
