日本高远町松本微生物研究所开发利用水库底淤泥制成饲料添加剂获得成功。经检测,在未污染的水库淤泥中一般含有36～39种微量元素、8～14种氨基酸以及5～6种酵母菌,而这些多是各种禽畜饲料中必需的营养素。因此该研究所把从水底吸出的淤泥经过水选、磁性分选和消毒、脱臭、脱色的处理后,得到一种具有综合成分的饲料营养添加剂。这种用人工配合制成的添加剂成本降低了85%～90%,该发明专利已被列为日本科技厅1992年选定的百项优秀发明之一。
Japan Takayama Matsumoto Institute of Microbiology Development and utilization of reservoir bottom sludge made of feed additives success. Tested in the uncontaminated reservoir silt contains 36 to 39 kinds of trace elements, 8 to 14 kinds of amino acids and 5 to 6 kinds of yeasts, and these are mostly all kinds of livestock feed nutrients. Therefore, the Institute of the sucked from the bottom of the mud through the water after the election, magnetic separation and disinfection, deodorization, decolorization of the treatment, to obtain a comprehensive nutritional ingredients with feed additives. The cost of this artificial additive is reduced by 85% -90%. This invention patent has been listed as one of the hundred outstanding inventions selected by Japan Science and Technology Agency in 1992.
