WebThis study suggests an underrecognized niche of SFB as nitrite producers during the handling of RIF. The production of nitrite along with the bacterial growth of 133 nitrite-producing SFB isolated from infant formula processing environments and end-products (70 mesophiles and 63 thermophiles) under RIF handling conditions were analysed. WebNitrate poisoning (toxicosis) in animals (especially ruminants) results from excess consumption of nitrates from plants or water or via ingestion of nitrate-containing fertilizers. The nitrate ion (NO 3–) is reduced to nitrite ion (NO 2– ), which is rapidly absorbed and leads to the formation of methemoglobin, which inhibits oxygen transport. mgh wife
