PROCESS FOR TREATING ORGANIC MATERIAL

The present invention includes a process of treating sewage sludge resulting from treatment of municipal or industrial wastewater using a composition consisting of a fermentation supernatant product obtained from a yeast culture solution and a nonionic surfactant， wherein the fermentation supernatant product is used in the field. It provides a method of treating sewage sludge with an enzyme， characterized in that it does not contain the active enzyme under conditions suitable for producing an active enzyme from sludge. The present invention provides a process for the treatment of sewage sludge with enzymes， which process comprises treating a sewage sludge resulting from the treatment of municipal or industrial waste water with a composition comprising a fermentation supernatant product from a Saccharomyces cerevisiae culture and a non-ionic surfactant， wherein said fermentation supernatant product is free of active enzymes， at conditions suitable for generating said active enzymes from said sewage sludge in situ.
