Abstract: With the analysis technologies of HPLC, TLC and test of antibacterial bio-activity, the stability of maituolaimycin, a novel macrolide antibiotic, during the process of separation and purification from the fermentation broth was studied in orthogonal test. The research included pH, temperature and protein-removing, the main factors that affected the stability of maituolaimycin, as well as their interaction, and the authors put out a reasonable technological process forward the separation and purification of maituolaimycin. Also the optimized separation and purification process after fermentation offers an analogy for other antibiotics.
