Carnobacteriaceae is a family of gram-positive, facultatively anaerobic bacteria commonly found in various environments such as water, soil, and spoiled food products. These bacteria are non-spore forming and often produce lactic acid as a metabolic byproduct, which can contribute to the spoilage of certain foods. Some species within this family have been associated with food-borne illnesses, while others have shown potential for use in biopreservation due to their ability to inhibit the growth of harmful bacteria.
