Abstract:
A biologically pure culture of the organism Xanthomonas campestris ATCC 31923 is disclosed. A process for the production of a functionalized dairy whey product characterised in that it comprises:
(a) providing a fermentation broth of whey and yeast extract; and (b) fermenting the broth with the organism Xanthomonas campestris ATCC 31923 to produce a functionalized dairy whey product containing a thickening polymer produced by the organism; and, optionally, (c) drying the functionalized whey product to form a dry functionalized whey product is also disclosed.
Dairy whey, a waste product of cheese production, may be functionalized by fermentation techniques to produce a functionalized whey which serves as a thickening agent in the food industry. This simultaneously provides a method for utilizing the whey waste produced.

Abstract:
An improved process for manufacture of fermented whey having a high concentration of propionic acid is disclosed in which the whey medium having a solids content ranging from about 0.5% to about 18% by weight is subjected to a sterilization step of heating to 121 °C psig for 15 minutes or subjected to a sterilization step of direct steam injection, for a period of about 4 to about 20 seconds. The sterilized whey medium is then inoculated with an unacclimated or acclimated mixed culture of a propionic acidproducing bacterium and a lactic acid-producing bacterium and incubated for a sufficient period of time to maximize the fermentation.
Abstract:
A process for manufacture of fermented whey having a high concentration of propionic acid comprises subjecting the whey medium having a solids content ranging from 0.5% to 18% by weight to a sterilization step of direct steam injection, for a period of 4 to 12 seconds. The sterilized whey medium is then inoculated with a propionic acid-producing bacterium and incubated for a sufficient period of time to maximize the fermentation.
