Polyglutamic Acid
Polyglutamic Acid

Product Description

γ-polyglutamic Acid (γ-PGA), was firstly found in the cells of Bacillus anthracis in the early 20th century, and it’s an important part of the cell capsule. As a biopolymer, it’s water-soluble, biodegradable and non-toxic. In 1942, researchers found that γ-PGA can be produced from some certain Bacillus by fermentation. Later, people also found γ-PGA in Japanese food-Natto, and at the same time, Bacillus natto was successfully extracted.


The basic structure of γ-PGA consists of L-glutamic acid and D-glutamic acid through  γ-amide bond. Large number of carboxyl groups along the molecule chain of γ-PGA can form hydrogen bonding in a molecule or between different molecules. Thus it has high water absorbility and moisture-retaining capability. The carboxyl group of γ-PGA can chelate heavy metal ions in soil, thus the soil quality can be improved and PH range can be controlled.
