Abstract

A study of phenotypic and genotypic characteristics was carried out on 182 strains isolated from soil of different geographical areas; the type strains were B. licheniformis, B. subtilis, B. pumilus, B. cereus and B. coagulans. The results showed, primarily on the basis of phenotypic features, that all the isolates belonged to the B. licheniformis species, however DNA relatedness studies revealed only 161 to be genetically related to B. licheniformis, the DNA relatedness levels ranging from 66 to 100%. The other 21 isolates appeared to be genetically distinct not only from B. licheniformis but also from B. subtilis and B. pumilus, where there were low levels of DNA relatedness (from 4 to 37%). Nevertheless the ARDRA results indicate that the 21 atypical isolates were phylogenetically related to B, licheniformis. Our data and the phenotypic homogeneity found suggest the presence of three different genomovars
