Lactobacillus curvatus is a species of lactic acid bacteria commonly found in various food environments, particularly in cured meats like sausages and fermented meat products. It is a gram-positive, non-spore-forming bacterium that plays a crucial role in the fermentation process of certain foods. L. curvatus is known for its ability to produce lactic acid through the fermentation of sugars, which helps lower the pH of the food product and contributes to its preservation. This acidification inhibits the growth of spoilage and pathogenic bacteria, thereby extending the shelf life of the product and enhancing its safety. Lactobacillus curvatus has also been studied for its potential probiotic properties and its ability to confer health benefits when consumed as a supplement.
