A systematic study of the effects of hydrophilic ionic liquids concentration and nature (alkyl chain length and type of anion) on the activity of Candida antarctica lipase B is here reported. The increase in the concentration of the studied ionic liquids is shown to cause a decrease of the enzyme activity, but the effect is dependent on the ionic liquid used. This behavior is partially due to t...

Aliphatic alcohols of chain lengths of 24–34 carbons have been found to be beneficial in treating hypercholesterolemia. Approximately 40% of beeswax is long-chain esters which can be transesterified in supercritical carbon dioxide to give these alcohols and fatty acid methyl esters. The methanolysis reaction was catalyzed by an immobilized lipase from Candida antarctica in flowing supercritical...

BACKGROUND Naringin is an important flavanone with several biological activities, including antioxidant action. However, this compound shows low solubility in lipophilic preparations, such as is used in the cosmetic and food industries. One way to solve this problem is to add fatty acids to the flavonoid sugar unit using immobilized lipase. However, there is limited research regarding hydroxyla...

Hydrolytic enzymes play important roles as biocatalysts in chemical synthesis. The chemical versatility and structurally sturdy features of Candida antarctica lipase B has placed this enzyme as a common utensil in the synthetic tool-box. In addition to catalyzing acyl transfer reactions, a number of promiscuous activities have been described recently. Some of these new enzyme activities have be...
