Nitrate- and nitrite-reducing probiotic feed additive
MetadataShow full item record
The present invention concerns novel probiotic compositions that increase nitrate- and nitrite-reduction in animals such as ruminants. The present invention thus provides compositions and methods for reducing nitrate/nitrite toxicity in such animals, or prophylactically protecting such animals from the effects of toxicity, such as methemoglobinemia. A novel strain of an unspeciated bacterial strain related to Paenibacillus species with nitrate- and nitrite-reducing capabilities is described. In conjunction with nitrate-supplemented diets, the probiotics of the present invention can also be utilized to reduce methanogenesis in livestock. Furthermore, the probiotic compositions of the present invention can be used to reduce the number and kind of food-borne pathogens, such as Escherichia coli and Campylobacter jejuni.
