Method for producing 3-position deacylated form of 16-membered macrolide antibiotic, microorganism used therefor, and novel macrolide antibiotic

摘要

A method of producing a 3-deacylated derivative of a 16-membered macrolide antibiotic using a microorganism belonging to the genus Phialophora or Preussia which comprises incubating said microorganism with a 16-membered macrolide antibiotic in a medium containing nutritional sources commonly used for incubating microorganisms, isolating a 3-deacylated derivative from the incubation medium, a microorganism to be used for the above method and a novel macrolide antibiotic.
