The description of product
Colistin is a cyclic cationic decapeptide linked to a fatty acid side chain, it belongs to a group of similarly structured bacterial antimicrobial peptides. Colistin sulfate is a polypeptide antibiotic which inhibits gram-negative bacteria by binding to lipopolysaccharides and phospholipids in the outer cell membrane of gram-negative bacteria.
Colistin sulfate, also known as colistin sulfate, Christian (Colistin), Polymyxin E(Polymyxin E), antiphytin, white or nearly white powder, odorless, bitter taste moistness, easily soluble in water, slightly soluble in methanol, ethanol, almost insoluble in acetone, ether, free alkali slightly soluble in water. Stable in PH3-7.5 range. Mycolistin sulfate is produced by Bacillus polymyxoides, which has strong antibacterial effect on gram-negative bacteria. It is used to treat intestinal diseases caused by gram-negative bacteria, and is used as a feed additive with obvious growth promoting effect. The combination of sulfadiazine effect is better.
Function of product
Colistin sulfate granules improved in the stability of potency in feed and exhibiting high solubility in spite of their being produced without using any expensive carrier or special equipment. Specifically, colistin sulfate granules consisting essentially of colistin sulfate and having particle diameters of 150 to 1500m, a specific surface area of 40 to 500 cm2/g, a wetting time of 5 minutes or below and a moisture content of 10 % or below.
Application
Colistin Sulfate is produced by polymyxa,and has strong antibacterial activity,against Gram-negative bacteria,is used of for treating intestinal diseases caused by Gram-negative bacteria.
