[Staphylococcal utilization of siderophores produced by bacilli of the genus Bacillus].

The ability of utilization by 24 staphylococcal strains of the siderophores of B. megaterium PCM 2010 and B. subtilis S was investigated. B. megaterium PCM 2010 produced hydroxamate class siderophores and B. subtilis S-catecholate class. The majority of staphylococcal strains--thirteen--could utilize these siderophores: eight strains from both these species and three strains did not possess any receptors for these chelators. The staphylococcal strains producing catecholate siderophores utilized catecholate chelators from B. subtilis S.
