    摘要: The present invention provides a process for preparing vancomycin hydrochloride using a mutant strain of Amycolatopsis orientalis (accession No. KCCM-10836P) comprising the steps of i) mutating and isolating a strain of Amycolatopsis orientalis (accession No. KCCM-10836P) for producing vancomycin from mother strain of Amycolatopsis orientalis (accession No. ATCC-19795) using NTG(N-methyl-N′-nitro-N-nitrosoguanidine) in the selection medium; ii) seed culturing the isolated mutant strain of Amycolatopsis orientalis (accession No. KCCM-10836P); iii) cultivating and fermenting said mutant strain of Amycolatopsis orientalis in the fermentation medium consisting of 12˜18 (w/v) % of dextrin, 2.2˜3.8 (w/v) % of bean powder, 1.9˜2.9 (w/v) % of potato protein, 0.10˜0.14 (w/v) % of sodium chloride and a small amount of minerals; iv) filtering vancomycin using microfilter in the cultivation broth by removing mycelia; v) purifying obtained vancomycin using column system compacted with cation exchange resin, anion exchange resin and absorbent resin; and vi) crystallizing the purified vancomycin with hydrochloric acid.
