Process for converting cephalosporin c. in an acid glutaryl - 7 - aminocephalosporanic.

摘要

The invention relates to a method of enzymatic oxidation improved in order to convert the cephalosporin c. in an acid glutaryl - 7 - amino cephalosporanic. & br / the process according to the invention comprises the use of a mixture containing a - d - amino acid oxidase whose esterase activity is 5% or less than the activity of the amino acid - - min. & br / this method is applied in the conversion of the cephalosporin c. in an acid glutaryl - 7 - amino cephalosporanic.
