Abstract:
Disclosed herein are fire-fighting compositions, and methods thereof, comprising a surfactant and a fraction of a fermentation mixture comprised of yeast exoproteins, where the proteins enhance ability of water to extinguish Class A, Class B and Class K fires, as defined by the National Fire Protection Association. In one embodiment the surfactant is optimized to wet and penetrate into the substrate, for example wood, as in a Class A fire. In a second embodiment, the surfactant is optimized for foaming to provide fire fighting protection in a Class B fire. Further embodiments include methods for using the same protein-surfactant fire fighting composition for both polar (e.g., alcohol) and non-polar combustible liquids. In yet another embodiment, methods are described where the proteins comprise stress shock proteins and where the residual protein-surfactant combination that is not degraded from the fire acts to stimulate resident bacterial populations to accelerate the biodegradation of residual hydrocarbons and surfactants from the composition. In another embodiment, the compositions are free of solvents, fluorine-free as in fluoro surfactants and fluoro-polymers.
Abstract:
Surfactant-containing compositions are described which include a protein component that has the effect of improving the surface-active properties of the surfactants contained in the compositions. The surfactant-containing compositions having the protein component demonstrate significantly lower critical micelle concentrations (CMC), reduced surface tensions, and reduced interfacial tensions than do comparable compositions having no protein component. In addition, the surfactant-containing compositions having the protein component has the effect of converting greasy waste contaminants to surface active materials.
Abstract:
Disclosed are skin wetting and penetrating compositions and methods, where the compositions comprise the following, or combinations thereof: a surfactant, yeast exo-proteins, a stabilizer, and optionally an oil, humectant, or dermatological active agent.
Abstract:
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.
