Cross-linked enzyme aggregates (CLEAs) of β-glucosidase were prepared and characterized. Under the optimum conditions, the activity recovery of CLEAs reached 84 %. The reduction by NaBH4 resulted in slightly lower activities of CLEAs, while their thermostability was enhanced. CLEAs were more thermally stable than free enzyme (half lives, 973 vs. 518 min at(More)
Enzymatic synthesis of ascorbyl undecylenate, an unsaturated fatty acid ester of ascorbic acid, was reported with biomass-derived 2-methyltetrahydrofuran (MeTHF) as the cosolvent. Of the immobilized lipases tested, Candida antarctica lipase B (CAL-B) showed the highest activity for enzymatic synthesis of ascorbyl undecylenate. Effect of reaction media on(More)
