Abstract
A process for the prodution of phosphatiolic acid is carried out by treating phospholipids with an enzyme capable of hydrolyzing a phospholipid into phosphatidic acid and a nitrogen-containing base and another enzyme capable of hydrolyzing a phospholipid into a diglyceride and a phosphoryl base. Further, another process for the production of phosphatidic acid is carried out by treating phospholipids with a treatment product of an oilseed is disclosed.
Claims26
A process for producing phosphatidic acid which comprises treating phospholipids with an enzyme capable of hydrolyzing a phospholipid into phosphatidic acid and a nitrogen-containing base and another enzyme capable of hydrolyzing a phospholipid into a diglyceride and a phosphoryl base;
- and recovering said phosphatidic acid.
A process for producing phosphatidic acid, which comprises:
- (1) treating phospholipids with an enzyme capable of hydrolyzing a phospholipid into phosphatidic acid and a nitrogen-containing base and another enzyme capable of hydrolyzing a phospholipid into a diglyceride and a phosphoryl base in a buffer comprising an organic solvent, an aqueous solution or a mixture of an organic solvent and an aqueous solution containing at least one substance selected from the group consisting of an alkali metal carboxylate, an alkaline earth metal carboxylate, a mixture of a carboxylic acid and an alkali metal salt and a mixture of a carboxylic acid and an alkaline earth metal salt;
- and
- (2) isolating said phosphatidic acid from the reaction mixture.
A process for producing phosphatidic acid, which comprises treating phospholipids with an enzyme from an oilseed selected from a ground oilseed or an extract of an oilseed in a buffer comprising an organic solvent, an aqueous solution or a mixture of an organic solvent and an aqueous solution containing at least one substance selected from the group consisting of an alkali metal carboxylate, an alkaline earth metal carboxylate, a mixture of a carboxylic acid and an alkali metal salt and a mixture of a carboxylic acid and an alkaline earth metal salt;
- and recovering said phosphatidic acid.
