Abstract:
A new family of lipopeptides produced by Bacillus thuringiensis, the kurstakins, was discovered in 2000 and considered as a biomarker of this species. Kurstakins are lipoheptapeptides displaying antifungal activities against Stachybotrys charatum. Recently, the biosynthesis mechanism, the regulation of this biosynthesis and the potential new properties of kurstakins were described in the literature. In addition, kurstakins were also detected in other species belonging to Bacillus genus such as Bacillus cereus. This mini-review gathers all the information about these promising bioactive molecules.
