FIELD: agriculture. ^ SUBSTANCE: ferments have improved characteristics compared to a ferment of wild type selected from high thermal stability, activity in wide pH range, high specific activity, wide substrate specificity and proteolytic stability. Besides, nucleic acids are proposed, which code these ferments, a vector containing these nucleic acids, a hostcell, which carries the vector, and a method to produce proposed phytase ferments from hostcells. This invention also relates to a food product or an animal fodder and to the method to make food product or fodder for animals, which includes addition of phytase ferment according to this invention to one or several ingredients of the prepared product or fodder. ^ EFFECT: using phytase ferments according to this invention as additives to animal fodders makes it possible to improve availability of organic phosphorus and to reduce contamination of environment with a phosphate. ^ 28 cl, 3 dwg, 2 tbl, 11 ex |
