Polyglutamic acid (y-PGA), also known as natto gum, is a high molecular peptide polymer synthesized from several glutamic acid monomers through microbial fermentation. It is rich in glutamic acid, glucose, protein and minerals. , vitamins and other biologically active substances.
Polyglutamic acid (??-PGA) is a sticky substance that was first discovered in ??Natto??. It is currently widely used in agricultural production and is called a new biostimulant. It is fully water-soluble, biodegradable, edible, and non-toxic. It is a biopolymer produced by microbial fermentation.
