Streptomyces formicae

From ActinoBase

This new species of Streptomyces was isolated in 2013 from the domatia (nest) of the Kenyan plant ant Tetraponera penzigi. It contains at least 45 secondary metabolite biosynthetic gene clusters, the vast majority of which are predicted to encode novel products. It also makes the formicamycins, which are potent against MRSA and have a high natural barrier to resistance.

Figure 1. Streptomyces formicae is best known for producing formicamycins but in fact the for biosynthetic gene cluster (BGC) encodes the biosynthesis of three groups of polyketides, the fasamycins, formicamycins and formicapyridines.
