**4. Some highlights on the LAB and possibilities for the future**

Without initially securing food safety, there can be no feeling of global security. This involves, among others, supplying the world's thriving population with safe and healthy food. The future is undoubtedly hopeful given the tremendous potential in the utilization of LABs as probiotics. One topic now being explored, for example, is the examination using whole genome sequence technology of probiotic propensities. Among other effects, the functions of probiotic LABs will be improved, and data may be utilized to further modify LAB genes [126]. More study is being undertaken on their usage as functional food components and will expand soon. The effects of probiotic LABs on the cells of breast and likes to have previously been researched to bridge the gap between the world's food, medicinal and health industries. However, it must be noted that the safety for the improvement of food is not a probiotic feature of lactic acid bacteria (LAB).

Over the recent decade, numerous researches have been carried out examining the molecular foundation for possible probiotic characteristics of prospective LAB strains and their products, drastically enhancing our biological understanding [127]. These findings have been and still can form the foundation for important in vitro and in vivo investigations for food, biomedical and pharmaceutical specialists. These studies are crucial. Preliminary findings from current study at the Northeastern Agricultural University's Key Laboratory of Dairy Science (KLDS).

Based on the research provided in this review, various strain combinations may thus be hypothetically utilized to evaluate the attenuation effects on gutmicrobiota with respect to obesity and T2D of probiotic LABs and *Bifidobacterium* species. To create new anti-obesity foods and dairy products, similar research evaluating the effect of various strains on the gut microbiota may be carried out. Such research might open fresh and new medicinal and food goods pipelines with huge industrial uses.
