title: Transfer of Defluvibacter lusatiensis to the genus Aquamicrobium as Aquamicrobium lusatiense comb. nov. and description of Aquamicrobium aerolatum sp. nov.
abstract: 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.
