Surfactin is a lipopeptide antibiotic produced by the cells of Bacillus subtilis ATCC 21332. A genetic locus responsible for surfactin production (sfp) was transferred from ATCC 21332 to JH642, a derivative of the standard B. subtilis 168. To study the

When Legionella pneumophila grows on agar plates, it secretes a surfactant that promotes flagellum- and pilus-independent "sliding" motility. We isolated three mutants that were defective for surfactant. The first two had mutations in genes predicted to encode cytoplasmic enzymes involved

The lipopeptide surfactin secreted by plant-beneficial bacilli has crucial biological functions among which the ability to stimulate immune-related responses in host tissues. This phenomenon is important for biological control of plant diseases but its molecular basis is still poorly understood.

In this work a low cost medium for the production of a biosurfactant by Bacillus subtilis LAMI005 and the kinetics of surfactin production considering the effect of initial substrate concentration were investigated. First, cashew apple juice supplementation for optimal production
