Abstract

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 ATCC 35681 (97·7 %). The main fatty acid of the paperboard isolates was C (34–45 %); straight-chain fatty acids made up 41–60 % of the total cellular fatty acids, thus distinguishing these strains from other 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, sp. nov., with IS 1 (=DSM 14472=CCUG 45566) as the type strain.
