HCID 27447Cephalexin

Procedure

The wet mycelium so obtained is suspended in M/30-phosphate buffer (pH 6.0), containing 7-aminodeacetoxycephalosporanic acid and D-α-phenylglycine methyl ester hydrochloride (0.4 g), at 28° C for 24 hours. The amount of Cefalexin formed in the reaction mixture is 0.095 g when determined by microbiological assay.
