Bacillus wiedmannii sp. nov., a psychrotolerant and cytotoxic Bacillus cereus group species isolated from dairy foods and dairy environments.

ABSTRACT: A facultatively anaerobic, spore-forming Bacillus strain, FSL W8-0169T, collected from raw milk stored in a silo at a dairy powder processing plant in the north-eastern USA was initially identified as a Bacillus cereus group species based on a partial sequence of the rpoB gene and 16S rRNA gene sequence. Analysis of core genome single nucleotide polymorphisms clustered this strain separately from known B. cereus group species. Pairwise average nucleotide identity blast values obtained for FSL W8-0169T compared to the type strains of existing B. cereus group species were <95 % and predicted DNA-DNA hybridization values were <70 %, suggesting that this strain represents a novel B. cereus group species. We characterized 10 additional strains with the same or closely related rpoB allelic type,
