Method for preparing feed yeast
A technology of feed yeast and yeast, which is applied in the field of microbial fermentation, can solve the problems of cumbersome and complicated process, prolonged fermentation period, and excessive precipitation of fermentation liquid, and achieve the effects of optimizing fermentation process, reducing production cost, and increasing dissolved oxygen coefficient
Examples
Embodiment 1
[0032] The preparation method of feed yeast, the steps are as follows:
[0033] According to the growth characteristics of Candida tropicalis, the growth of Candida tropicalis mainly depends on growth factors such as nitrogen source, carbon source, inorganic salts, trace elements in the medium, and these nutrients are mainly provided by the ingredient medium. include:
[0034] 1. Culture medium preparation
[0035] 1. Glucose mother liquor is a by-product of glucose production. Take the glucose mother liquor with a concentration of 42%, and the glucose mother liquor with a reducing sugar content of ≥80% for use;
[0036] 2. After extracting phytin with corn soaking water, the waste liquid is clear and transparent, and the pH value is controlled to 5.8. In order to reduce the ash content and pH value, the phytin waste liquid needs to undergo ion exchange, and the phytin waste liquid is handed over for later use;
[0037] 3. Mix the glucose mother liquor and corn soaking water...

[0051] The steps to produce feed yeast are as follows:
[0052] 1. Culture medium preparation
[0053] According to the growth characteristics of Candida utilis, the growth of Candida utilis mainly depends on growth factors such as nitrogen source, carbon source, inorganic salts, trace elements in the medium, and these nutrients are mainly provided by the ingredient medium. Prepare as follows:
[0054] 1. Glucose mother liquor is a by-product of glucose production, take the glucose mother liquor with a concentration of 42% and a reducing sugar content of ≥80% for use;
[0055] 2. The waste liquid after extracting phytin from corn soaking water is clear and transparent, with a pH of 5.8. In order to reduce the ash content and pH value, the waste liquid after extracting phytin from corn soaking water must undergo ion exchange, and the liquid will be used for later use;
[0056] 3. Mix the glucose mother liquor and the postpartum liquor, control the concentration to 10%, adjust...

[0069] The steps to produce feed yeast are as follows:
[0070] According to the growth characteristics of brewer's yeast, the growth of brewer's yeast mainly depends on growth factors such as nitrogen source, carbon source, inorganic salt, trace elements in the medium, and these nutrients are mainly provided by the ingredient medium. Prepare as follows:
[0071] 1. Culture medium preparation
[0072] 1. Glucose mother liquor is a by-product of glucose production, take the glucose mother liquor with a concentration of 42% and a reducing sugar content of ≥80% for use;
[0073] 2. The waste liquid after extracting phytin with corn soaking water is clear and transparent, with a pH value of 5.8. In order to reduce the ash content and pH value, the waste liquid after extracting phytin with corn soaking water must undergo ion exchange, and the liquid will be used for later use;
[0074] 3. Mix the glucose mother liquor and the post-delivery liquor, control the concentration to 10%...
