The present invention relates to a process for preparing a biopreparation based on copper, zinc and manganese, by microbial conversion. According to the invention, the process consists in selecting the cells of S. Cerevisiae which have resisted to various concentrations of ZnSO4 - 10,000 ppm (1 % solution), CuSO4 - 10, 000 ppm (1% solution), MnSo4 - 12, 500 ppm (1% solution), there being obtained the laboratory pre-inoculum with the cell viability of 2,14X 10^4 cfu/ml and then the laboratory inoculum which was used in a percentage of 15% as seeding material for a well-established fermentation medium, with the correction of the pH during the culturing within the 5 - 5.5 range, obtained the biopreparation which is separated by filtration, the biomass being purified, pasteurized and dried, finally reaching a concentration of yeast biomass of 14 g/l, which exhibits a high degree of incorporation of the minerals Cu (1016 ppm), Zn (1123.8 ppm) and manganese (331 ppm).
