Embodiment 1

[0051] Mixed fermentation process using distiller's grains as the main feed raw material, one of the strains used is Brevibacterium lactofermentum, its preservation number is CICC 10227, and the second strain is Candida tails , whose preservation number is CICC 1314, and the strains are preserved on the slant of the culture medium.

[0052] The Brevibacterium lactis fermentum and Candida utilis were respectively cultured by three-stage seeds, mixed and inoculated in the mixed seed medium to obtain the mixed seed liquid of the Brevibacterium lactis fermentum and Candida utilis, and then the mixed seeds The inoculum solution was inoculated in a mixed fermentation medium with a humidity of 50% at an inoculation amount of 1:10. After the inoculated mixture was fermented in stages at a temperature of 30-37°C, the fermented product was then placed in a 50°C refrigerator. After drying at high temperature and packaging, the finished product is obtained.

[0053] The tertiary seed cul...

Embodiment 2

[0071] Brevibacterium lactis fermentum and Candida utilis were respectively subjected to three-stage seed culture, and the three-stage seed liquid was mixed and inoculated in the mixed seed medium to obtain a mixed seed liquid of Brevibacterium lactis fermentum and Candida utilis, and then The mixed seed solution is inoculated in a mixed fermentation medium with a humidity of 60% according to the inoculum amount of 1:10, and the inoculated mixture is fermented in stages at a temperature of 30-37°C, and the fermented product obtained is then placed After drying and packaging at a temperature of 40°C, the finished product is obtained.

[0072] The culture process of the mixed seed liquid of described fermenting Brevibacterium lactis and Candida utilis is:

[0073] Brevibacterium lactis fermentum and Candida utilis were mixed according to the ratio of 1:1, and then inoculated into the seed medium according to the inoculum size of 1:10, the culture temperature was 28°C, the stirri...

Embodiment 3

[0079] Brevibacterium lactis fermentum and Candida utilis were respectively subjected to three-stage seed culture, and the three-stage seed liquid was mixed and inoculated in the mixed seed medium to obtain a mixed seed liquid of Brevibacterium lactis fermentum and Candida utilis, and then The mixed seed solution is inoculated in the mixed fermentation medium with a humidity of 55% according to the inoculum amount of 1:10, and the inoculated mixture is fermented in stages at a temperature of 30-37°C, and the obtained fermented product is placed in the The finished product is obtained after drying and packaging at a temperature of 60°C.

[0080] The culture process of the mixed seed liquid of described fermenting Brevibacterium lactis and Candida utilis is:

[0081]Brevibacterium lactis fermentum and Candida utilis were mixed according to the ratio of 1:0.01, and then inoculated into the seed medium according to the inoculum size of 1:10, the culture temperature was 30°C, the s...

Abstract

The invention discloses a method for processing feedstuff such as distilled grains, etc. by mixed fermentation, and the strain is brevibacterium lactofermentus and candida utilis; the technique is that: strain liquid cultured by a third class seed is mixed and then inoculated in a mixed fermentation medium; the mixed seed liquid is inoculated in the mixed fermentation medium with 50 to 60 percent of humidity according to 1:10 of inoculum concentration; the obtained mixture is fermented by sectional fermentation at the temperature of 30 to 37 DEG C, and the obtained leavening is dried at the temperature of 40 to 60 DEG C, and packed so as to obtain a finished product; the invention adopts the sectional fermentation mode which is aerobic firstly and then is anaerobic, thus eliminating rape seed cakes or thioglucoside and gossypol in cottonseed crumb, increasing the total content of protein in the distilled grains, degrading the alcohol substances and decomposing non-starch polysaccharide substances such as cellulose, etc.; the content of the cellulose of the obtained feedstuff finished product is reduced from 25 to 11 percent, and the protein content is increased from 15 percent to 30 to 40 percent; the feeding effect of animals is good.

Description

technical field [0001] The invention relates to a method for microbial fermentation of distiller's grains and other mixed feed materials. Specifically, the invention relates to a method for treating distiller's grains and protein raw materials such as soybean meal, vegetable cake, cotton meal or other miscellaneous meal by mixed fermentation of lactic acid bacteria and yeast Mixture method. Background technique [0002] Distiller's grains are not only rich in crude protein (about 20%), but also rich in crude fiber (about 25%), crude fat (about 10%), B vitamins, and inorganic elements such as phosphorus and potassium. The nutritional value and development and utilization value of distiller's grains are extremely high. In addition, trace beneficial components such as amino acids, ribonucleic acid, and purines produced by microorganisms may also exist in distiller's grains, all of which are incomparable to grains. Therefore, research on distiller's grains has been going on al...
