Two types of lipase, Candida rugosa lipase (CRL) and porcine pancreas lipase (PPL), were used to hydrolyze virgin coconut oil (VCO). The hydrolysis process was carried out under four parameters, VCO to buffer ratio, lipase concentration, pH, and temperature, which have a significant effect on hydrolysis of lipase. CRL obtained the best hydrolysis condition at 1 : 5 of VCO to buffer ratio, 1.5% of CRL concentration, pH 7, and temperature of 40°C. Meanwhile, PPL gave different results at 1 : 4 of VCO to buffer ratio, 2% of lipase concentration, pH 7.5, and 40°C. The highest hydrolysis degree of CRL and PPL was obtained after 16 hours and 26 hours, reaching 79.64% and 27.94%, respectively. Besides, the hydrolysis process was controlled at different time course (every half an hour) at the first 4 hours of reaction to compare the initial hydrolysis degree of these two lipase types. FFAs from hydrolyzed products were isolated and determined the percentage of each fatty acid which contributes to the FFAs mixture. As a result, medium chain fatty acids (MCFAs) made up the main contribution in composition of FFAs and lauric acid (C12) was the largest segment (47.23% for CRL and 44.23% for PPL).

The synthesis of aromatic aldehyde oxime esters (considered fragrances, antifungal and antimicrobial compounds) was achieved by two reactions which combine the advantage of green chemistry and biocatalysis. In the first step, the mechanochemical oxime synthesis by means of grindstone milling of six solid aromatic aldehydes and hydroxylamine hydrochloride in the presence of FlorisilR, as the best support, yielded the aromatic aldehyde oximes 1–6 with high purity and good yields. In the second step the lipase catalyzed acetylation reaction at 40°C for three days of those oximes with vinyl and isopropenyl acetates as acyl donor substrates and ethyl acetate as the solvent, yielded the aromatic aldehyde oxime esters. With Candida antarctica lipase (Novozyme 435), the conversions of oximes 1–6 into their esters were ≥ 99% according to the 1H NMR results and it was the best biocatalyst compared with others such as Candida rugosa (CRL), porcine pancreas lipase and the recombinant lipase LipMatCCR11 from the thermophilic strain Geobacillus thermoleovorans CCR11 cloned and expressed in Escherichia coli BL21 (DE3), all of which showed lower yields.
