(57) [Summary] [Problem] In an agriculture, forestry and fisheries industry and various other industries, a composition containing a methionine / zinc complex and an amino acid is used as a catalyst, Processing into additives in a form that is easy to use when used as a biochemical catalyst. SOLUTION: One mole of a higher amino acid having 4 to 8 carbon atoms and a lower amino acid 1 to 2 having 2 to 3 carbon atoms. Preparation of a very easy-to-use form of a methionine zinc complex solution by bringing methionine and a zinc salt into contact with a solution obtained by heating 5 mol of the methionine in water or a polyol and then making the solution uniform. . |
