Fermentation technology degrades DDGS toxins

"text-align: center;"img src""alt"fermentation technology degradation DDGS toxin" title "fermentation technology degradation DDGS toxin"DDGS as a feed raw material, widely used in livestock and poultry productionHowever, part of DDGS because of its acquisition process and enrichthed corn raw materials of mycotoxins, or in the preservation process by mold pollution, added to the animal diet on pigs, chickens, cattle and other farmed animals caused great harmat present, the methods of removing mycotoxins are physical treatment, chemical treatment and biodegradationAlthough the physical treatment and chemical treatment have achieved some success, the detoxification effect is limited, and it is easy to cause the loss of nutrients, the cost is highThe enzyme solution in the biological treatment method is mainly to use the degradation effect of certain enzymes, destroy the mycotoxin or reduce its toxicity, but in practical application, it will encounter such problems as enzyme intolerance, high temperature inactivation, high cost, incomplete degradation of toxins and so onThe microbial degradation method has many advantages, such as mild conditions, enzymes that produce a variety of degradation toxins in the fermentation process1 Technical Route"text-align: center";"img src"""alt"fermentation technology degradation DDGS toxin" title""fermentation technology degradation DDGS toxin" "style" text-text-product quality management level: "center"""""stechnical road map""""Stu1 technical road map, fermentation, fermentation, fermentation, fermentation, fermentation, fermentation, fermentation, fermentation, fermentation, fermentation, fermentation, fermentation, fermentation, fermentation, fermentation, fermentation, fermentation, fermentation, fermentation, fermentation, fermentation, fermentation, fermentation, fermentation, fermentation, fermentation, fermentation, fermentation, fermentation, fermentation, fermentation, fermentation, fermentation, fermentation, fermentation, fermentation, fermentation, fermentation, fermentation, fermentation, fermentation, fermentation, fermentation, fermentation, etcAmong them, fermentation raw materials, fermentation equipment, testing methods and management level is relatively easy to grasp, and fermentation bacteria and fermentation process is more difficult to grasp, therefore, the fermentation of bacteria screening, fermentation process optimization is the key to the projectspecies: black cactus, white rot, less root mold and other fungi and ostreptobacrine, sprigs spores, red cocline and other bacteria have the ability to degrade aflatoxin; On the basis of previous studies, the appropriate strain was initially selected, and then the fermentation test was used for resieve to select a combination of strains or strains with strong toxin degradationfermentation process: According to the most suitable growth conditions of the selected strain and its optimal growth conditions for toxin degradation, the conditions of the fermentation process are optimized2 Effect Analysis Economic Benefits: DDGS after fermentation sales gross profit of about 500 yuan / ton, production costs to 160 yuan / ton, wage costs to 120 yuan / ton, annual output of 10,000 tons of factories, annual profit (500-120-80) x 10,000 yuansocial benefits: the use of microbial fermentation DDGS can not only degrade the aflatoxin, corn erythromycone, vomit toxin and other mycotoxins, but also can produce some beneficial substances, improve palatability, bacteria can also supplement beneficial bacteria for farmed animals, regulate the micro-ecological balance of the animal intestines, improve animal immunity, promote animal growth, reduce the use of antibiotics, reduce the use of animal waste to the environment, and let people eat meat,Source: , Biofeed Engineering Research Centre
