Bioprotective Cultures: Lactic Acid Bacteria strains are; These cultures can show a bio-protective or inhibitory effect against other microorganisms as a result of their competition for nutrients; production of bacteriocins or other antagonistic compounds. Many species of these microorganisms have been used as protective cultures, including not only lactic acid bacteria (e.g., lactobacilli, streptococci, enterococci, lactococci) and bifidobacteria but also E. coli and species of Bacillus , yeasts such as Saccharomyces , and molds such as Aspergillus . However, the most common protective cultures for human consumption belong to the genera of Lactobacillus (e.g., Lactobacillus casei, Lactobacillus acidophulus, Lactobacillus rhamnosus, Lactobacillus johnsonii, and Lactobacillus reuteri ) and Bifidobacterium (e.g., Bifidobacterium bifidum, Bifidobacterium longum, Bifidobacterium breve ) The use of protective cultures has become a popular interest, especially in the dairy, meat, and seafood industries , because they are safe for consumption (GRAS) and naturally dominate the microbiota of many foods.
