Natto polypeptide is an MJ50 strain obtained by mutating Bacillus subtilis by South Korea Zhengming Co., Ltd. with internationally advanced proprietary biotechnology. Its metabolites contain nattokinase, L arginine, angiotensin converting enzyme inhibitor, soybean isoflavone and other substances. Natto polypeptide has the functions of dissolving thrombus, reducing blood viscosity, improving blood circulation, softening and increasing vascular elasticity. It is a biological product used for non-drug treatment in Korea. The researchers found that nattokinase has two production processes. One is that nattokinase belongs to polymer, and it only needs to be extracted. But in this way, the vitamins in natto and Bacillus natto will also be discarded together. Another method is selective extraction of natto and its by-products. In this way, all substances contained in Bacillus natto can be extracted. It is clear at a glance who is superior and who is inferior to the two extraction methods. The produced nattokinase powder contains all substances that can be produced by Bacillus natto. Because of this, natural nattokinase powder with high stability can be produced [1].

Zhengming natto polypeptide is a MJ50 strain obtained by using internationally advanced proprietary biotechnology to mutate Bacillus subtilis. Its metabolites contain nattokinase, L arginine, angiotensin converting enzyme inhibitor, soybean isoflavone and other substances. Natto polypeptide can make up for the deficiency of commonly used cardiovascular and cerebrovascular drugs, and it is a biological product used for non-drug treatment in Korea. [
