Paenibacillus granivorans sp. nov., a new Paenibacillus species which degrades native potato starch granules.

From a native potato starch-degrading enrichment culture, strain A30 had been isolated and had tentatively been identified as a member of the Bacillus firmus/lentus group (Wijbenga et al. Appl. Microbiol. Biotechnol. 35, 180-184, 1991). In this paper the isolate A30 is further characterized using phylogentic analysis of the 16S rDNA and determination of a number of additional phenotypic characteristics. These data are compared to those of Paenibacillus amylolyticus, P. chibensis, and P. thiaminolyticus. It is concluded that strain A30 is a new Paenibacillus species, for which the name Paenibacillus granivorans is suggested.
