Secondary metabolites produced by marine actinomycete streptomyces sp. G246

Abstract

In a recent study, we described two new lavandulylated flavonoids, along with eight known compounds from the culture broth of a Streptomyces sp. (strain G246), isolated from the sponge Halichondria panicea, collected in the sea of Son Tra peninsula (Da Nang). A comparison study was conducted to differentiate between solid and liquid fermentation technique for secondary metabolites production of strain G246. In this paper, we report the isolation and structural characterization of nine secondary metabolites (1-9) from strain G246 by solid state fermentation. Compound 2 was the only one similarity between these fermentation techniques.
