Abstract
Description
technical field
[0001] The invention relates to the technical field of medicine, in particular to a preparation process of salinomycin granule preparation based on improving the spray effect. Background technique
[0002] Salinomycin is a polyether ionophore antibiotic produced by Streptomyces albus. Salinomycin granule preparation not only has good antibacterial effect, low toxicity and low residue, simple production process, readily available raw materials and low price, it is one of the most promising veterinary drugs recognized in the market.
[0003] Salinomycin has a strong inhibitory and killing effect on most Gram-positive bacteria and various coccidiosis, and it is not easy to produce drug resistance and cross-resistance. It is excreted quickly and the residual amount is extremely low. It can be used to prevent diarrhea, Promote production and increase survival rate. Salinomycin has a cation transport function in cells, especially for potassium ions, sodium ions, ...
Examples
Embodiment 1
[0021] The preparation process of the salinomycin granule preparation based on improving the spray effect comprises the following steps:
[0022] 1) Preparation of acidic fermentation broth: adjust the pH of the salinomycin fermentation broth with a drug price of 80,000u / ml to 4.0 with sulfuric acid;
[0023] 2) Pretreatment of the acidic fermentation broth: keep the pH-adjusted acidic fermentation broth at 60°C for 3 hours;
[0024] 3) Plate and frame filtration: Add sodium hydroxide as a saponification agent to the acidic fermentation broth obtained in step 2), add perlite, diatomaceous earth and light calcium carbonate as filter aids, and add sodium carbonate to adjust the pH to 8.5, full saponification;
[0025] 4) Preparation of salinomycin feed liquid: add a certain amount of light calcium carbonate to the fermentation liquid obtained after saponification in step 3) to make salinomycin feed liquid, the amount of light calcium carbonate added is for acidic fermentation ...
