Abstract

The cheese whey is an important residue of the dairy industry in Uruguay, so it is necessary to fi nd new viable alternatives for its use. We evaluated the cheese whey as a base for the development of a probiotic native Lactobacillus paracasei HA9-2 strain culture media. Several carbohydrate concentrations, salt effects as magnesium sulfate and manganese sulfate, a nitrogen source and a commercial prebiotic addition as acacia rubber were assayed. Comparative assays in lactic bacteria commercial media known as MRS were made. The results indicate that the cheese whey with 70 g/l of carbohydrates is an ideal media for the strain development. The salt addition as well as the nitrogen source and commercial prebiotic addition improve and increase the biomass. Finally, if we analyze the costs balance, and we compare the costs of the media and the increase of the biomass, we can conclude that the cheese whey is the best for the HA9-2 probiotic strain as the only component of the media. The acacia rubber prebiotic effect on this strain was also tested.
