Detailed Description:
Cas No. :9057-02-7 Removal of heavy metals and radionuclide
Gamma-poly-glutamic acid (纬-PGA) is a natural occurring, multi-functional, and biodegradable biopolymer. It is produced through fermentation by Bacillus subtilis using glutamic acid. PGA is consists of glutamic acid monomers crosslinked between 伪-amino and 纬-carboxyl groups, and the molecular weight of PGA is usually between 100~1000 kDa. It is water-soluble, edible and non-toxic towards human, and is environment friendly. It has broad applications in the fields of medicine, food, cosmetics, and water treatment.
