Abstract

The present invention provides a production technology of high-purity teicoplanin. The production technology comprises the following steps: 1) a slant culture medium, a seed culture medium and a fermentation culture medium are prepared; 2) fermentation liquid is prepared; 3) an eluent is prepared; and 4) a finished product is obtained. Mg2+ can improve activity of glucose oxidase of actinoplanaceae cells, Fe3+ can promote growth of live bacteria and formation of endospores, and the Mg2+ and Fe3+ produce an active center through a synergistic action, effectively conduct catalytic fermentation and increase yield of the teicoplanin.

Description

technical field [0001] The invention relates to the technical field of pharmaceutical engineering, in particular to a production process of high-purity teicoplanin. Background technique [0002] Teicoplanin, also known as Taikotamycin, was first discovered in 1975. It is a vancomycin family glycopeptide antibiotic obtained after fermentation and extraction of specific actinomycetes. It is an antibiotic mixture composed of many compounds with very similar chemical structures. [0003] Teicoplanin (teicoplanin) is a representative series of glycopeptide antibiotics. Clinically, it is mainly used to treat severe infections caused by sensitive bacteria such as Staphylococcus aureus and Streptococcus, such as endocarditis, osteomyelitis, sepsis, and infections of the respiratory tract, urinary tract, skin, and soft tissues. Its antibacterial mechanism is that the substance can hinder the mutual combination of peptidoglycan synthesis intermediates in the process of cell wall syn...
