Category: γ-PGA

γ-PGA can be used as a fertilizer by dilution of its microbial fermentation solutions, which contain free PGA, amino acids, sugars as well as minerals, and can be safely applied directly to crops. 

γ-PGA has high water absorbability, which can increase the water content of soil at depths between 0 and 20cm by 1.5-2.8%, and at soil depths between 20 and 40 cm by 1-1.5%, thus giving higher resistance to drought.

In addition, γ-PGA biodegrades naturally to amino acids, which is non-toxic to soil and environment. Research shows that γ-PGA as a compound fertilizer is more profitable than other similar products and the market demand is also very large.

γ-PGA (Gamma-poly-glutamic acid) 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 α-amino and γ-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.
