Interpretive Summary: Many newly described spore-forming bacteria within the Bacillus group can degrade a variety of complex, sugar-containing compounds called polysaccharides. This degradative ability makes these organisms potentially useful industrially. Because the classification of these organisms is not clear, studies were done to determine the proper classification of eight showing interesting activities. Based on comparative studies of their genetic structure and fatty acid contents, these eight new bacteria were reclassified as members of the Paenibacillus group.
Technical Abstract: We determined the taxonomic status of eight species (Bacillus alginolyticus, Bacillus chondroitinus, Bacillus curdlanolyticus, Bacillus glucanolyticus, Bacillus kobensis, Bacillus lautus, Bacillus peoriae, and Bacillus thiaminolyticus) using the 16S rRNA gene sequence and cellular fatty acid compositional analyses. Phylogenetic analyses clustered these species closely with the Paenibacillus species. Like the Paenibacillus species, the eight Bacillus species contained anteiso- C15:0 fatty acid as a major cellular fatty acid. The use of a specific PCR amplification primer designed for differentiating the genus Paenibacillus from other Bacillaceae showed the eight Bacillus species were members of genus Paenibacillus. Based on these observations, the eight Bacillus species were transferred to the genus Paenibacillus.
