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 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.

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 are methods of removing oil from an aqueous surface, comprising: surrounding an oil spot on the aqueous surface with an oil-absorbing material; and introducing a solution comprising a surfactant to the oil spot. Also disclosed are the above methods where the oil is not mechanically directed towards the oil-absorbing material, or where the oil-absorbing material is not mechanically directed towards the oil. Also disclosed are the above methods further comprising introducing a solution comprising a protein/surfactant complex to the oil spot, where the protein/surfactant complex comprises a protein component obtained from the fermentation of yeast, comprising a mixture of multiple intracellular proteins, at least a portion of the mixture including yeast polypeptides obtained from fermenting yeast and yeast stress proteins resulting from subjecting a mixture obtained from the yeast fermentation to stress.

Abstract: A composition including the fermentation supernatant from a fermentation of yeast is intended to be conveniently introduced through the wastewater plumbing system of a private home or other facility into a septic system servicing the home or other facility to substantially accelerate the ability of the bacteria resident in the septic system to substantially digest biologically available organic compounds present in the septic system, and methods of accomplishing the same.

Abstract: Systems and methods for reducing biofilms are described. The systems and methods are particularly suitable for use with conventional aqueous crossflow filtration systems, such as reverse osmosis systems. The addition of the enzyme/surfactant compound has been found to enhance the effectiveness of conventional crossflow filtration processes by decreasing or inhibiting the growth of biofilms and other contaminants.
