A new technology developed by Harbin Institute of Technology on the use of microbial liquid fermentation technology to transform potato slag to produce single-cell protein feeds has recently solved the problem of changing potato waste from potatoes to waste and changing the environment. This problem.
At present, China produces more than 70 million tons of potatoes annually. When it is used in the production of starch, it produces a large amount of potato pulp and juice containing cellulose, vitamins, and other nutrients. Since there is no effective treatment technology, it can only be allowed to discharge, which not only causes huge waste of resources. It also destroyed the ecological environment.
In 2004, under the support of scientific research projects such as the “National Natural Science Foundation of China†and the “Science and Technology Support Program of the Ministry of Science and Technologyâ€, Prof. Yang Qian of the Institute of Biological Engineering of Harbin Institute of Technology led the task group to use microbiological fermentation technology to convert potato residues into production. Single cell protein feed research.
They used the potato potato dregs produced during starch processing as the main raw material, used yeasts and other microorganisms to formulate microbial agents, and used a combination of excellent strains for the production of single cell proteins to select combinations, and determined the optimal fermentation process conditions for producing single cell proteins through scale experiments. And launched a complete process route.
The relevant departments have detected that the single-cell protein feed produced by this technology is rich in nutrients and is easily digested and absorbed by livestock. The cost-effectiveness is higher than that of similar products in the market, and no pollution is produced in the production process. The economic, environmental and social benefits are relatively high. obvious.
Experts said that the popularization and application of this technology will effectively alleviate the tight feed situation in China's animal husbandry and develop a new protein feed source for the development of animal husbandry.
At present, this technology has applied for two Chinese national invention patents and is currently applying for international invention patents.
Underground led light we use as LED Outdoor Lighting for garden lights, lawn lights, ground lights, floor lights etc. The underground LED light is embembed underground, it is Ip68 led fixture, and we can classify the underground led lighting into round underground led light, and linear strip underground led light according to the underground led lights housing structure.
