Abstract:
A method for inhibiting yeast and mold growth in a material in need thereof which comprises:(a) adding to the material an effective amount to inhibit mold and yeast growth in the material of a product produced by a process which comprises incubating live cells of a Lactobacillus having all of the identifying characteristics of Lactobacillus casei var. rhamnosus NRRL-B-15972 in a nutrient medium containing a sulfur containing organic compound, a protein source and a carbon source, which induce the formation of a yeast and mold inhibiting product in the nutrient medium, wherein the product in the nutrient medium inhibits Penicillium oxalicum spores in an assay with the product and the Penicillium oxalicum spores mixed; and(b) treating the nutrient medium which contains live cells, so as to produce the product in a form containing live cells, dead cells or no cells, wherein the product is polar, non-protein, non-lipid, has a molecular size of less than 1000 daltons, insoluble in chloroform or hexane and soluble in butanol and acetane, is temperature stable at -70.degree. C. to 100.degree. C. and is stable at a pH between 3 to 10.
