Natural fermentation relies on indigenous bacteria, which are a rich resource for lactic acid bacteria (LAB). Lactic acid bacteria play an important role in meat preservation and fermentation. They are able to decrease the pH by lactic acid production, produce bacteriocins which prevent the growth of pathogenic and spoilage microorganisms, provide diversity of sensory properties, contribute to the development of flavour, colour and texture and
