The basis of tryptone soy polymyxin broth

Tryptone soy polymyxin broth is a selective enrichment medium, and its core is used for enrichment and culture of Bacillus cereus in food, medicine and other samples, which can directionally inhibit miscellaneous bacteria and promote the proliferation of target bacteria. Its formula takes tryptone and soybean peptone as basic nutrient sources, which provides sufficient nitrogen and carbon sources for bacterial growth. Polymyxin B is added as a selective inhibitor, which can effectively inhibit gram-negative bacteria and some non-target gram-positive bacteria without affecting the growth of Bacillus cereus. This culture medium needs to be used with specific additives to improve its function, and it is an important basic culture medium for screening Bacillus cereus in microbial detection, which can significantly improve the accuracy of subsequent separation and identification.
