Abstract
The species of agriculturally important Bacillus strains have previously been plagued with inconsistencies in their taxonomic treatment. Most of these problems can be traced to the historical lack of distinguishing phenotypic characters and easy genotyping methods to provide appropriate taxonomic placement. Currently, the two most important clades in this area are the Bacillus subtilis group and the B. cereus group. The B. subtilis group encompasses species that are important as biological control agents, plant growth promoters, probiotics, sources of food processing enzymes, and food fermentation inoculants, while the B. cereus group comprises species that impact agriculture as food poisoning agents and human and livestock pathogens and are extensively used for the biological control of insects. Modern DNA sequencing techniques have resolved many of the historical conflicts and inconsistencies. This chapter provides the current updated status on the taxonomy of these two important Bacillus groups and provides guidance on how to identify isolates from these groups.
