FIG 2.

Evolutionary relationship between B. licheniformis strains using the MLST database. An unrooted phylogenetic tree of B. licheniformis strains was based on concatenated sequences of six housekeeping genes in the absence (top) and presence (bottom) of B. subtilis 168 using the neighbor-joining method. It can be inferred that the lineage of strain G-1 separated from the lineage of other strains earlier, but, as expected, it is still very close to other B. licheniformis strains when a B. subtilis 168 outgroup is included.
