IMPROVEMENT STRATEGIES FOR THE ENZYMATIC PRODUCTION OF BIODIESEL IN THE PRESENCE OF PRIMARY ALCOHOLS
In order to improve the enzymatic production of biodiesel, the reuse of an immobilized preparation of Candida antarctica lipase B (CALB) was assayed under di ff erent conditions. The improvement included: (1) reuse of CALB in the presence of ethanol (EtOH), (2) reuse of CALB in the presence of metha...
