Abstract: A feed additive composition includes a protective agent, lecithin, an acidic or neutral amino acid, and water. A method of producing a feed additive composition includes preparing a molten mixture of a protective agent, lecithin, and an acidic or neutral amino acid, and immersing the molten mixture in water or an aqueous liquid to obtain a solidified mixture. Feed additives may be obtained by such method. The protective agent may include a hydrogenated vegetable oil or hydrogenated animal oil having a melting point of higher than 50° C. and lower than 90° C.

Abstract: A food additive composition for ruminants of the dispersion type and a method of continuously producing the same. This food additive composition for ruminants, which contains 40% by weight or more but less than 65% by weight of a basic amino acid and has rumen bypass properties, is formulated into granules in an arbitrary shape which are scarcely classified when added to a silage or another feed. Thus, attempts have been made to develop a method of producing granules by which the milk yield of a lactation cow can be increased. Namely, it is intended to provide a food additive composition for ruminants which contains at least one protecting agent selected from among a hardened vegetable oil and a hardened animal oil having a melting point higher than 50° C. but lower than 90° C., 0.05 to 6% by weight of lecithin, water and 40% by weight or more but less than 65% by weight of a basic amino acid.

Abstract: An inexpensive heat treatment method for producing dried microbial cells is provided, wherein the method does not result in lowering the quality of the microbial cells or causing pulverization. The method includes a step of heating microbial cells to between 200 to 450° C. for 1 to 30 seconds.

Abstract: A mutant tyrosine repressor that does not require tyrosine to induce expression of tyrosine phenol-lyase gene is obtained by introducing a mutation into a tyrosine repressor. A microorganism which is able to express large amounts of tyrosine phenol-lyase is obtained by introducing the mutant tyrosine repressor into the microorganism. The microorganism is useful for producing L-DOPA.

Abstract: A mutant tyrosine repressor that does not require tyrosine to induce expression of tyrosine phenol-lyase gene is obtained by introducing a mutation into a tyrosine repressor (tyrR), isolated from Pantoea agglomerans, or a tyrosine repressor (tyrR) which is encoded by SEQ ID NO. 1 and its derivative. A microorganism which is able to express large amounts of tyrosine phenol-lyase is obtained by introducing the mutant tyrosine repressor into the microorganism. The microorganism is useful for producing L-DOPA.

Abstract: The present invention relates to a method which can prevent browning of hydrolyzed protein obtained by enzymatic hydrolysis of vegetable protein material. A vegetable protein material containing saccharides is mixed with the fungal culture and is subjected to enzymatic hydrolysis in a liquid reaction system. The reaction is conducted first at a temperature ranging from 15° C. to 39° C. with aeration and agitation, and then, after stopping the aeration, the reaction is conducted and completed at a temperature ranging from 40° C. to 60° C.

Abstract: A hydrolyzed protein which can be used as seasonings or the like is produced by heating and maintaining an aqueous dispersion of a protein-containing starting material, while under an acidic condition, with a plate-type heat exchanger using a liquid as a heat medium to make the aqueous dispersion substantially aseptic and then subjecting the resulting aqueous dispersion with an action of a proteolytic enzyme.
