Chlorination of cephalexin with chloroperoxidase from Rathayibacter biopuresis
 An enzyme preparation that exhibits cephalosporin chloroperoxidase activity is isolatable from a microorganism species of the Rathayibacter genus. This enzyme preparation can convert cephalexin to cefaclor in a single step. A particular, unique microorganism that can provide the cephalosporin chloroperoxidase enzyme preparation is Rathayibacter biopuresis.
