Analytical Methods：

The purity of the isolated 7-Aminocephalosporanic Acid is analysed by reverse phase C18 HPLC using a Shimadzu HPLC system (LC- 10AT, Shimadzu, Japan) equipped with a Merck C18 column (5μm, Merck, Ger- many). The mobile phase was 2﹪ Acetonitrile in 20 mM AMMONIUM ACETATE pH 5.7 at 1.2 ml/min flow rate. Sample size was 20μl. The absorbance of the eluent was monitored at 260 nm. 7-ACA from Sigma, USA, served as a standard.
