Antifungal activity improved by coproduction of cyclodextrins and anabaenolysins in Cyanobacteria

2015

Department of Chemistry, Nanoscience Center, University of Jyväskylä, FI-40014, Jyväskylä, Finland Cyclodextrins are cyclic oligosaccharides widely used in the pharmaceutical industry to improve drug delivery and to increase the solubility of hydrophobic compounds. Anabaenolysins are lipopeptides produced by cyanobacteria with potent lytic activity in cholesterolcontaining membranes. Here, we identified the 23- To 24-kb gene clusters responsible for the production of the lipopeptide anabaenolysin. The hybrid nonribosomal peptide synthetase and polyketide synthase biosynthetic gene cluster is encoded in the genomes of three anabaenolysin-producing strains of Anabaena.We detected previously u…
