PROCESSES FOR PRODUCING VANCOMYCIN

摘要

Decoloring processes appropriate for the economical production of vancomycin on an industrial scale whereby a favorable decoloring effect and a high yield can be both established, characterized by bringing vancomycin into contact with adsorbent phenol resins which can be regenerated without resort to any organic solvents. These processes are typified by one comprising passing an acidic vancomycin solution through an adsorbent phenol resin to thereby give the eluate and another one comprising passing a weakly alkaline vancomycin solution through an adsorbent phenol resin and eluting the vancomycin thus adsorbed with an acidified lower alcohol to thereby give the eluate.
