A series of 9 lactonic lipopeptide biosurfactants was isolated from Bacillus licheniformis IM 1307 as representatives of the lichenysin group and we propose to name them lichenysins G. They were recovered from the culture medium as complex mixtures of molecules having different peptide sequences and different structures of beta-hydroxy fatty acids. Their separation was achieved by a reversed-ph...

A screening of marine bacteria for antimicrobial activity resulted in the isolation of Bacillus pumilus (SP21) from a sediment sample collected in the Bahamas. A bioassayguided fractionation led to the isolation of five surfactin analogs, glycocholic acid, amicoumacins A and B in addition to three new compounds named lipoamides A–C. The chemical structure of all the bioactive compounds was eluc...

Biosynthetic adaptation of endophytic bacteria to chemically support host plant is very remarkable. Hence these organisms from medicinal plants are considered as highly valuable sources for natural products with diverse bioactivity. Their metabolite diversity and biosynthetic versatility have been increasingly explored for drug discovery. In this study, an endophytic Bacillus mojavensis with br...
