Abstract:Breast milk-derived probiotics possess development and utilization advantage due to their safety and adaptability to human environment. The isolation, screening, and development of lactic acid bacteria in breast milk have become research hotspots in the dairy and lactic acid bacteria industry. Domestic and foreign scholars have carried out a lot of studies on the isolation and identification of lactic acid bacteria in breast milk, as well as the screening and functional evaluation of probiotics. Delving into the probiotic properties of lactic acid bacteria in breast milk and exploring their potential in industrial applications will propel the high-quality development of China's lactic acid bacteria industry. This review summarizes the advances in research on the diversity of lactic acid bacteria in breast milk and the screening, development, and utilization of probiotics, aiming to provide insights into understanding the diversity of lactic acid bacteria in breast milk and the research on probiotics derived from breast milk.
