| 摘要 |
Disclosed herein are compositions containing enzymes, particularly acting at the interface between two immiscible phases where the rate of enzymatic activity is increased by addition of a blend of surfactant(s) and a mixture derived from yeast fermentation, that contain non-enzymatic exo-proteins released by yeast in response to a non-lethal stress. The enzymes include those that work at the interface between an aqueous solution and a water immiscible phase, liquid or solid, such as oil, fat, cellulose, lignin, etc. including, but not limited to the following or combinations thereof: lipases, polysaccharase, lignase, cellulase and the like, in which the substrate of an enzymatic reaction forms a phase, segregated from the aqueous solution in which the enzymes are typically operating. Disclosed herein are methods for improving a washing solution with the use of these compositions, where the enzyme-protein-surfactant solution can be used in such applications as: laundry, spot remover, pre-laundry, dishes, hard surface cleaning, wastewater treatment, cellulose breakdown as in ethanol production, lignin utilization, environmental remediation, industrial cleaning, and agricultural applications. |

1. A composition comprising:
i. non-enzymatic exo-proteins derived from a yeast fermentation process, ii. a surfactant selected from the consisting of an anionic, nonionic, cationic, zwitterionic surfactant or combinations thereof, and iii. an enzyme component comprising lipase; and wherein the composition forms a water-immiscible segregated phase and the rate of enzyme activity on the surface or in the solution is compared to a rate of enzyme activity in the absence of the non-enzymatic exo-proteins and the surfactant. |
