    摘要: The present invention relates to a biocatalytic method of preparing a mono-acylated polyol catalyzed by triacylglycerol lipase mutants, as for example derived from Candida antarctica lipase B (CALB); a biocatalytic method of enantioselectively preparing an asymmetric mono-acylated polyol, catalyzed by the same enzyme mutants; as well as the use of a mutated triacylglycerol lipase in a method of preparing mono-acylated polyols. The invention also provides novel mutants, coding sequences thereof, and recombinant microorganisms carrying said coding sequences.

    摘要: A method is disclosed for the generation of triacylglycerols from gums that have been separated from an oil product. The gums are treated with an enzyme having PLC activity, which results in the formation of diacylglycerols and phosphates, and treated with an enzyme having PLA activity, which results in the formation of lyso-phospholipids and free fatty acids. The diacylglycerols and the free fatty acids from these two separate reactions then combine in the presence of the enzymes to generate new triacylglycerol molecules.

    摘要: A method for degumming an oil composition comprises the steps of (a) providing an oil composition containing a quantity of phospholipids, (b) contacting said oil composition simultaneously with one or more phospholipase A enzymes and one or more phospholipase C enzymes, under conditions sufficient for the enzymes to react with the phospholipids to create phospholipid reaction products, and (c) separating the phospholipids reaction products from the oil composition, the remaining oil composition after the separation being a degummed oil composition, whereby during step (b) the reaction of said one or more phospholipase A enzymes proceeds at a faster rate than it would in the absence of said one or more phospholipase C enzymes, and wherein the reaction of step (b) continues for a duration of less than about one hour.
