    摘要： An optically active alcohol of this invention is obtained from a process using an enzyme having the ability to conduct preferentially a transesterification reaction with a triglyceride and an (R,S)-alcohol represented by a general formula: ##STR1## wherein X indicates alkyl group having a carbon number of 2-10, Y indicates alkyl group having a carbon number of 1-3, CF.sub.3 or CN, and X.noteq.Y. In this process, the (R,S)-alcohol of the above formula (1) and the triglyceride are reacted under substantially anhydrous conditions. The obtained ester is resolved and the optically active alcohol which contains richly either R- or S-alcohol is produced the optically active alcohol is efficiently obtained by an industrially advantageous biochemical method.

    摘要： A process for the selective hydrolysis of triglyderides to 2-acyl glycerides is disclosed. This process uses a primary lower alkyl alcohol selected from the group consisting of methanol, the primary butanols and the primary pentanols and 2-butanol, an aqueous buffer system and a 1,3-lipase. The 2-acylmonglycerides can be used to make stereospecific 1,2-diacyl glycerides or 2,3-diacyl glycerides through esterification with acid anhydrides and 1,3-lipase catalysis. Stereospecific 1,2,3-triglycerides can be made from these materials by standard esterification reactions under conditions which control rearrangement.

    摘要： A biochemical process and apparatus for use in the process are described. The process comprises reacting (a) a hydrophobic substrate with (b) a solution or dispersion comprising a hydrophilic substrate and an enzyme catalyst, by contacting through a porous thin membrane, wherein the hydrophobic and hydrophilic substrates are incompatible with each other. The apparatus comprises a main body and a porous thin membrane provided inside the main body so as to define therein at least two channels, wherein a hydrophobic substrate and a solution or dispersion comprising hydrophilic substrate and an enzyme catalyst are contacted through the thin membrane by passing them through the respective channels.

    摘要： A method for the enzymatic transesterification useful for modification of a lipid, which comprises continuously or repeatedly contacting an enzyme or an enzyme preparation having transesterification activities with a fresh supply of a dried fatty ester substrate such as fats and oils of glycerides. The enzyme or the enzyme preparation has transesterification activities (Kr value) of 0.01 or more as well as lipolytic activities. The enzyme preparation is prepared by dispersing, adsorbing or bonding an enzyme having lipolytic activities in or to a carrier and drying the resulting mixture at an adequately slow initial drying rate to activate or increase the transesterification activities of the enzyme.
