    The present invention relates to a kind of productive technology for producing the microbiological product of nutrient yeast, and it uses the Zn resisting or Fe resisting yeast strain in the course of strain culture. In the seed jar or commodity jar inoculating culture course, the ZnSo4 or FeSO4 is added to the culture medium separately. Through the appropriate technological process, the Zn-rich or Fe-rich yeast is obtained. The vitamin D2 yeast can also be obtained by the following steps:ergosterol-rich yeast strain is used in the course of strain culture, the produced ergosterol-rich yeast is processed by moistening and screening, and after the ultraviolet radiating and low temp. drying, the finished product is obtd. The advantages of said invention are simple operation in productive process and good repeatability in technological process.
