摘要:The present invention discloses isolation of Penicillin Acylase (PA) from Achromobacter sp CCM 4824 expressed in recombinant strain E. coli BL21 CCM 7394 bearing the recombinant plasmid pKXIP1 and processing of PA into biocatalyst useful for the industrial synthesis of antibiotics. More particularly the invention discloses a synthesis of semi-synthetic β-lactam antibiotics in the reaction mixture consisting of activated acyl-donor (D-p-hydroxyphenylglycine methyl ester or amide for Amoxicillin and Cefadroxil; D-phenylglycine methyl ester or amide for Ampicillin and Cephalexin) and nucleophile (6-APA or 7-ADCA) catalyzed by PA obtained from recombinant E. coli BL21 CCM 7394 as the biocatalyst.

摘要:The invention relates to an in-situ process for the preparation of amoxicillin trihydrate from sugarcane juice without isolation of the intermediates produced during the reaction sequence viz penicillin G and 6-aminopenicillanic acid. The invention provides an in-situ cost effective and environment friendly process in which no separate synthesis of the intermediates, no purification cost and no crystallization cost for the intermediates is required.
