Coproduction of surfactin and iturin A, lipopeptides with surfactant and antifungal properties, by Bacillus subtilis

C Sandrin et al. Biotechnol Appl Biochem. 1990 Aug.

Abstract

Of the 13 strains of Bacillus subtilis tested for the coproduction of the lipopeptide surfactin and the antifungal lipopeptides of the iturin family, only 1 produced both lipopeptides with a high yield. The cultures were made in a synthetic medium. Several L-amino acids and various carbon sources were good substrates for the lipopeptide production. The maximum yield of surfactin was about 110 mg/liter and that of iturin A about 39 mg/liter/absorbance unit for the best strain, B. subtilis S 499.
