Proposal of Virgibacillus proomii sp nov and emended description of Virgibacillus pantothenticus (Proom and Knight 1950) Heyndrickx et al, 1998

A polyphasic study of strains originally received as Bacillus (now Virgibac illus) pantothenticus, along with strains representing species belonging to Bacillus, Halobacillus and Paenibacillus, was undertaken using amplified r DNA restriction analysis (ARDRA), fatty acid methyl ester (FAME) analysis, SDS-PAGE of whole-cell proteins and routine diagnostic characters comprisin g 61 biochemical tests in the API system and 15 observations of vegetative cell and sporangial morphology, It revealed the presence within Virgibacill us of an as yet undescribed new species, for which the name Virgibacillus p roomii is proposed; V, proomii can be distinguished from V, pantothenticus and members of Bacillus sensu stricto, and from members of Paenibacillus an d other aerobic endospore-forming bacteria, by routine phenotypic tests. Th e type strain of Virgibacillus proomii is LMC 12370(T).
