Abstract

The invention discloses a two-step process for recovery of thuringiensin, comprising adsorbing the thuringiensin from fermentation broth by calcium silicate, and dissociating the thuringiensin by dibasic sodium phosphate. The resulting thuringiensin can be further purified by using semi-preparative HPLC and electrodialysis to remove the excess salts from the recovered thuringiensin solution.
