    摘要： A combination vibrator, aerator, and liquid-injection device for in-situ treatment of sediments to facilitate the reduction, elimination or removal of substances by microbiological or chemical treatment. In the preferred embodiment of the invention, the aerator and liquid-injection elements are attached to an internal concrete vibrator which penetrates and agitates the sediments. Air released from the aerator supplies oxygen to microorganisms in the sediments for the aerobic biodegradation of target substances. Liquids released under pressure from the liquid injector introduce microorganisms, nutrients or other chemicals such as oxidizers and detergents for degradation or solubilization of target substances.

    摘要： A stabilized aqueous enzyme composition comprising water, from about 0.1% to about 75% by weight of a detergent surfactant selected from the group consisting of anionic surfactants or anionic surfactants and one or more non-anionic detergent actives, from about 0.001% to about 10% by weight proteolytic enzyme, and an effective amount of an enzyme stabilizer having the formula:X--O--(C.sub.n H.sub.2n O).sub.a --H [I]wherein "X" is an organic radical having from 14 to 22 carbon atoms, "a" is an integer from 10 to 26, and "n" is an integer from 2 to 4, and provided that "X" has a hydrophobicity similar to a linear alkyl group having from 14 to 22 carbon atoms.
