specific Embodiment approach
[0016] A kind of embodiment of the production technology of the fermented bean curd of the present invention with nutrition and health care function, comprises the following steps:
[0017] A. Screen mucormycetes strains: isolate and screen strains with large hydrolytic transparent circles and small sedimentation circles from fermented bean curd as the primary screening strains, and then inoculate them in the fermentation medium to measure their protease activity, so as to select the one with the highest protease production ability strains;
[0018] B. Inject N + Ion: Take the mucormyces strain with the highest protease ability screened as the starting strain, select the optimal mutation dose, inject N + Ion, through subculture, test the genetic stability of mutant strains, measure protease activity by shaking flask fermentation, and finally determine the mutant strain with the highest enzyme activity and the most stable genetic traits;
[0019] C. Production of high-yield m...
