Description
Technical field
The present invention relates to the feed medicated premix and make field, be specifically related to a kind of extracting method of enramycin.
Technical background
Enramycin (Enramycin), have another name called enramycin, enramycin, enramycin, belong to polypeptide antibiotics, by actinomycete fermentation, it is a kind of organic bases by amino acid molecular and molecular composition of fatty acids, wherein amino acid molecular forms the ring-type polypeptide structure, and fatty acid molecule is positioned at the polypeptide structure end., according to the difference of end fatty acid molecule, be divided into enramycin A (C
