Optimization of Enzymatic Synthesis of Ampicillin Using Cross-Linked Aggregates of Penicillin G Acylase
Penicillin G acylase from E. coli TA1 was immobilized by Cross-Linked Enzyme Aggregates (CLEA), a new method for immobilization. This biocatalyst and commercial immobilized penicillin G acylase (PGA-450) were used to study the effect of pH, temperature and substrate concentration on the synthesis of ampicillin from phenyl glycine methyl ester (PGME) and 6-aminopenicillanic acid (6-APA). Compare...

متن کاملPreparation of Cross-Linked Glucoamylase Aggregates Immobilization by Using Dextrin and Xanthan Gum as Protecting Agents
In this paper glucoamylase from Aspergillus niger was immobilized by using a modified version of cross-linked enzyme aggregates (CLEA). The co-aggregates were cross-linked with glutaraldehyde; meanwhile dextrin and xanthan gum as protecting agents were added, which provides high affinity with the enzyme molecules. The immobilized glucoamylase was stable over a broad range of pH (3.0–8.0) and te...

متن کاملCross-linked Enzyme Aggregates of Catalase from Bovine Liver
Stabilization of multimeric enzymes is one of the major challenges in biocatalysis, because dissociation of subunits can inactivate the enzyme. Catalase (CAT; EC 1.11.16) is a homotetramer containing Fe-protoporphyrin IX in its active site. CAT breaks down hydrogen peroxide into water and molecular oxygen. In this study, crosslinked enzyme aggregates of bovine liver CAT (CAT-CLEAs) were prepare...
