Paenibacillus odorifer, the Predominant Paenibacillus Species Isolated from Milk in the United States, Demonstrates Genetic and Phenotypic Conservation of Psychrotolerance but Clade-Associated Differences in Nitrogen Metabolic Pathways.

ABSTRACT: Paenibacillus is a spore-forming bacterial genus that is frequently isolated from fluid milk and is proposed to play a role in spoilage. To characterize the genetic and phenotypic diversity of Paenibacillus spp., we first used rpoB allelic typing data for a preexisting collection of 1,228 Paenibacillus species isolates collected from raw and processed milk, milk products, and dairy environmental sources. Whole-genome sequencing (WGS) and average nucleotide identity by BLAST (ANIb) analyses performed for a subset of 58 isolates representing unique and overrepresented rpoB allelic types in the collection revealed that these isolates represent 21 different Paenibacillus spp., with P. odorifer being the predominant species.
