Solubilization and degradation of lipids in medium from e.g. sewage water or septic tank water, by adding lipase, urea, urease and bactericide

摘要

The solubilization and degradation of fatty acid esters comprises adding: (1) at least one lipase to hydrolyze fat and release fatty acids; (2) at least one urea and urease; and (3) at least one bactericide . The solubilization and degradation of fatty acid esters such as triglycerides, cerids and steroids (which are the lipid components of fat) comprises adding: (1) at least one lipase to hydrolyze fat and release fatty acids; (2) at least one urea and urease to potentiate the activity of the lipase by continuous alcalinization of the medium to produce surfactants solubilizing the fat by formation of micelles; and (3) at least one bactericide to strengthen the activity of the lipase by releasing enzymatic systems and to degrade fatty acids into water-soluble compounds. An INDEPENDENT Claim is also included for a composition for solubilizing and degrading fatty acid esters comprising: (1) at least one lipase (at least 0.5 %). The lipase is in the form of granules (containing the enzyme at at least 1 %); (2) at least one urea and urease (at least 0.83 %). The urease is in the form of a powder (containing the enzyme at at least 39 %); and (3) at least one bactericide.
