Bacillus funiculus sp. nov., novel filamentous isolates from activated sludge.

A novel filamentous Bacillus strain, NAF001T, was reported previously that produces endospores and spore-like resting cells; the latter outgrow by budding. Phylogenetic analysis based on 16S rDNA gene sequences reported in the same paper speculated on the proposal of a novel species for this isolate. This communication describes the DNA-DNA relatedness of strain NAF001T to various members of the genus Bacillus and its whole-cell fatty acid and quinone profiles, in order to authenticate the creation of a novel species, for which the name Bacillus funiculus sp. nov. is proposed. The type strain is NAF001T (= JCM 11201T = CIP 107128T). Further, features of the binding points between filaments of strain NAF001T that enable it to form extremely long filaments are captured by electron microscopy.
