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.

Process of enzymatic interesterification maintaining a water content of

This invention provides a process for concentration and separation of an eicosapentaenoic acid ester comprising:

Process for concentration and separation of highly unsaturated fatty

A gene which provides resistance to at least one methionine derivative and is capable of enhancing accumulation of S-adenosyl-L-methionine (SAM) in a cell, a hybrid plasmid having the same, a cell transformed with the above hybrid plasmid, and a process for producing SAM using the above cell. According to the present invention, SAM, which has various therapeutic effects, can be producing in a large amount at a low cost.

Gene capable of enhancing S-adenosyl-L-methionine accumulation and

This invention provides a method of concentrating and separating .gamma.-linolenic acid esters and/or arachidonic acid esters characterized in that a fatty acid ester mixture containing .gamma.-linolenic acid ester and/or arachidonic acid ester is brought in contact with crystalline aluminosilicate zeolites to make adsorption and desorption. According to this invention, high purity .gamma.-linolenic acid and/or arachidonic acid ester(s) may be obtained on industrial scale.

Method of concentration and separation of unsaturated fatty acid esters

A method of measuring a combustible component in a liquid or gas employs a gas having a high oxygen content, instead of air or an inert gas, as the carrier gas to thereby improve drastically the scope and accuracy of measurement by a semicondutor gas sensor. The carrier gas having a high oxygen content is supplied into a combustible component sampler formed from a gas-permeable membrane and disposed in the liquid or gas to be tested so that the combustible component may be diffused into the carrier gas through the gas-permeable membrane. The carrier gas entraining the combustible component therein is introduced into a detector having a semiconductor gas sensor, in which the combustible component is detected, and its concentration is determined continuously or intermittently.

Method for measuring the concentration of a combustible component

Apparatus for cultivating aerobic microorganisms is provided which comprises cell multiplying compartment and cell ripening compartment. The invention also provides a cultivation process using the same apparatus. The invention improves oxygen transfer rate and utilization of oxygen, thus enabling cultivation at a higher concentration of microorganisms as compared with any conventional process.
