Immobilized cells of Bacillus subtilis, process for their immobilization and use of the preparation for separating the 3-acetoxy group from 7-beta-acylamide cepholosporan acids

摘要

The immobilised Bacillus subtilis cells are used to prepare 7- beta -acylamido-3-hydroxymethyl-3-cephem-4-carboxylic acids from reversibly protected 7- beta -acylamidocephalosporanic acids.
