Peptaibol Production and Characterization from and Their Action as Biofungicide.

Peptaibols (P), are a class of biologically active peptides isolated from soil, fungi and molds, which have interesting properties as antimicrobial agents. P production was optimized in flasks by adding sucrose as a carbon source, 2-aminoisobutyric acid (Aib) as an additive amino acid, and cell debris as an elicitor. P were purified, sequenced and identified by High-performance liquid chromatography (HPLC)coupled to mass spectrometry.
