Abstract: A process of an enzymatic interesterification in a low water content condition, which comprises subjecting a reaction liquid containing (a) a fat or oil and (b) a member selected from the group consisting of (i) another fat or oil, (ii) a fatty acid ester with a lower alcohol and (iii) a fatty acid to the action of a lipase in the form of dried Rhizopus cells while maintaining the water concentration between 5 and 1000 ppm in the reaction liquid during the reaction. In accordance with the process of the present invention, an interesterification of fat or oil can be carried out efficiently in a high yield.

Abstract: A machine tool having a gate-type construction and provided with a tool magazine (11). The tool magazine (11) is mounted between a pair of support portions (3a) of a gate-shaped column (3) and above a work support table (2). The tool magazine (11) is composed of a plurality of tool holders (16) each holding a tool (17), and a driving device (18) for moving the tool holders (16) back and forth. This arrangement permits an efficient use of the working space on the work support table (2), and makes it possible to reduce the sizes of the support table (2) and a bed (1).
