Abstract:
of Streptomyces regensis was isolated from soil to produce a novel antibiotic AGPM of a strong biological activity of antitumor The strain was irradiated by UV after treatment with LiCl to give a AGPM yield of 1 87?10 2 mg mL 1 , 2 2 times higher than that of the original strain The optimum UV irradiation time was 30~60 s and the best LiCl concentration was 0 05~0 09 mol/L The fermentation of AGPM was conducted in a 30 L stirred tank, the maximum yield of AGPM using the mutants reached 1 85?10 2 mg mL 1 , while that using the original strain was only 0 85?10 2 mg mL 1
