Lipases - Enzymes for Biocatalytic Asymmetric Synthesis

Biocatalytic Synthesis of Polyglycerol Polyricinoleate: A Comparison of Different Commercial Lipases

Polyglycerol polyricinoleate (PGPR, E-476) is a powerful water-in-oil emulsifier 1–5 used to manufacture stable pan release agents for the bakery industry and to stabilize low fat margarine systems with high water content. However, its main application is in the chocolate and confectionery industry,6,7 since it improves the flow properties of chocolate and vegetable fat coatings by lowering the...

Biocatalytic Synthesis of Flavonoid Esters by Lipases and Their Biological Benefits.

Several studies have described important biological activities of flavonoids such as coronary heart disease prevention, hepatoprotective, anti-inflammatory and anticancer activities, enzyme inhibition activity, and antibacterial, antifungal, and antiviral activities. Flavonoids show promising activity as natural plant-based antioxidants due to their antioxidant and free radical scavenging prope...

Enzymes used in detergents: Lipases

Microbial lipases are an important group of biotechnologically valuable enzymes, because of the versatility of their applied properties and ease of mass production. Lipases of microbial origin are widely diversified in their enzymatic properties and substrate specificity, which make them very attractive for industrial applications. This review describes the applications of microbial lipases in ...

Biocatalytic synthesis of vanillin.

The conversions of vanillic acid and O-benzylvanillic acid to vanillin were examined by using whole cells and enzyme preparations of Nocardia sp. strain NRRL 5646. With growing cultures, vanillic acid was decarboxylated (69% yield) to guaiacol and reduced (11% yield) to vanillyl alcohol. In resting Nocardia cells in buffer, 4-O-benzylvanillic acid was converted to the corresponding alcohol prod...
