Abstract
Surfactin is produced fromssp. containing sfp gene (lipopeptide biosurfactants produced by fermentation). Production of surfactin at present is mainly by liquid fermentation, but the production costs are high due to difficulty in purification resulted from addition of the defoaming agent during the production process. Therefore, present invention conducts physical or chemical mutation onsubsp. isolated from Thailand seawater shrimp ponds and screens for the mutant strain ofsubsp. based on sfp gene expression and then produces surfactin from the mutant strain by semi-solid state fermentation.
