Identification of lactic acid bacteria with bio-preservative potential isolated from contaminated avian blood obtained at the slaughterhouse

Blood is a common by-product of the meat industry, which has several potential applications in the animal feed industry. However, since blood is highly susceptible to microbial spoilage, blood and its fractions are often not suitable ingredients for the feed industry. Biopreservation appears as an a...
