HI,WELCOME TO JIANGSU JIUWU HI-TECH CO.,LTD.

Colistin sulphate, also known as polymyxin E, is an antibiotic produced by certain strains of the bacteria Paenibacillus polymyxa. Colistin sulphate is a mixture of the cyclic polypeptides colistin A and B and belongs to the class of polypeptide antibiotics known as polymyxins. Colistin sulphate is effective against most Gram-negative bacilli.

Colistin sulphate Separation and Purification technology is suitable for industrial production of modern antibiotics using microbial synthesis, which can replace traditional purification technologies such as adsorption, precipitation, solvent extraction and ion exchange.

Separation process provides optimum solutions with the unique characteristics without any chemical reaction, no phase change, does not destroy the biological activity, environment-friendly.
