Abstract

Bacillus licheniformis is exploited industrially for the production of enzymes and has been shown to exhibit pathogenic properties. Because of these divergent characteristics, questions arise concerning intraspecies diversity. A comparative study by means of combined repetitive polymerase chain reaction, rpoB and gyrA sequencing, 16S rDNA targeted probe analysis, DNA–DNA hybridizations, gelatinase tests and antibiotic susceptibility tests was performed on a set of strains from diverse sources, including strains with pathogenic potential. B. licheniformis was found to consist of two lineages that are distinguished genotypically.
