When sensitivity to decoyinine is given by mutation to L-phenylalanine-producing mutants of the genus Brevibacterium and Corynebacterium, the productivity of L-phenylalanine of the new mutants is improved.

Method for producing L-phenylalanine by fermentation

L-lysine is produced by culturing mutants of Corynebacterium or Brevibacterium which are sensitive to fluoropyruvic acid.

Method for the production of L-lysine

A glyceride product is prepared by interesterifying a glyceride mixture in the presence of a lipase as a catalyst with a dihydric alcohol, a trihydric alcohol, or mixture thereof, said glyceride mixture being composed of at least two different glycerides or at least one glyceride and at least one fatty acid.

Method of producing improved glyceride by lipase

Mutants of glutamic acid producing strains of Brevibacterium which are more sensitive to N-palmitoylglutamic acid than the parent strains require less surfactant to suppress excessive biotin activity in a fermentation medium for permitting glutamic acid production and correspondingly less antifoaming agent without loss of glutamic acid yield.
