Patent ID: 8679824

Claim:
A method of making a fermentation broth formulation, comprising incubating a first mixture comprising: (a) one or more fermentation broths comprising microbial cells, (b) a first organic acid component comprising at least one 1-5 carbon organic acid and/or a salt thereof in an amount of from 0.1% to 15% by weight of said mixture, and (c) a second organic acid component comprising at least one 6 or more carbon organic acid and/or a salt thereof in an amount of from 0.025% to 5% by weight of said mixture, for a time period of 8 to 36 hours, and under conditions of at a temperature of 20° C. to 50° C., and a pH of 3.5 to 5, that result in at least a 4 log decrease in viable cells in said one or more fermentation broths, thereby making a fermentation broth formulation.
