The microflora isolated from food-packaging board is dominated by paenibacilli; a number of these micro-organisms have been characterized using a polyphasic approach. The highest 16S rRNA gene similarity was found between these isolates and Paenibacillus azotofixans ATCC 35681T (97?7 %). The main fatty acid of the paperboard isolates was C16 : 0 (34–45 %); straight-chain fatty
acids made up 41–60% of the total cellular fatty acids, thus distinguishing these strains from other Paenibacillus species. The paperboard isolates produced cyclodextrins from starch. The spore surface had a characteristic ribbed ornamentation. Spores and vegetative cells frequently had
pilus-like appendages. Based on phylogenetic data and phenotypic and chemotaxonomic characteristics, it is proposed that the isolates represent a novel species, Paenibacillus stellifer sp. nov., with IS 1T (=DSM 14472T=CCUG 45566T) as the type strain.
