NOVELTY - A Frateribacillus flavoalbus (new species of Frateribacillus) comprising a 16S ribosomal (r)RNA which comprises a base pair sequence exhibiting 98.7% or more homology with respect to a 1416 base pair sequence (SEQ ID NO: 1) fully defined in the specification or one of 12(1406) base pair sequences (SEQ ID NO: 8-19) all fully defined in the specification, is new.    USE - The F.flavoalbus is useful for processing organic waste chosen from excrement, organic sludge, foodstuff residue and animal excrement, and decomposing protein (all claimed).    ADVANTAGE - The F.flavoalbus exhibits excellent sporulation ability.    DETAILED DESCRIPTION - A Frateribacillus flavoalbus (new species of Frateribacillus) comprising a 16S ribosomal (r)RNA which comprises a base pair sequence exhibiting 98.7% or more homology with respect to a 1416 base pair sequence (SEQ ID NO: 1) fully defined in the specification or one of 12(1406) base pair sequences (SEQ ID NO: 8-19) all fully defined in the specification, is new. The F.flavoalbus is F.flavoalbus YM17 strain (NITE BP-01764), F.flavoalbus YM17-2 strain (NITE BP-01948), F.flavoalbus YM17-3 strain (NITE BP-01949), F.flavoalbus YM17-4 strain (NITE BP-01950) or F.flavoalbus YM17-5 strain (NITE BP-01925), and the 16S rRNA has DNA-DNA hybridization homology value of 70 % or more. The strain (a) is gram-negative bacterium and capable of forming spore, (b) provides negative result for oxidase test and positive result for catalase test, (c) does not produce acid when D-galactose or sucrose are added to Luria-Bertani (LB) culture medium having pH of 8.0 and comprising 1% glucose and 2% sodium chloride, and produce acid when D-glucose, lactose, D-mannitol, glycerol or N-acetylglucosamine is added, (d) exhibits optimal growth at 45-55 degrees C, where proliferation is not confirmed at 35-65 degrees C, (e) exhibits optimal growth at pHs of 7-8, where proliferation is not confirmed at pH of 5.7-10, (f) does not proliferate when 7% sodium chloride is added to CYC culture medium, (g) produces menaquinones (MK7), (h) comprises cell wall peptidoglycan which comprises amino acid composition of alanine, glutamic acid, and meso-diaminopimelic acid, (i) has GC contents of 51.2-52.4% in genomic DNA , and (j) has fatty acid composition of iso-C16:0.
