How can the function and effect of polyglutamic acid (γ-PGA) be sold in the fertilizer and cosmetic fields? The biopolymer material polyglutamic acid (γ-PGA) is based on glutamic acid and combined with organic Carbon source, nitrogen source and mineral, biopolymer synthesized by microbial fermentation, is one of only four kinds of polymer homopoly amino acids synthesized by microorganisms, with high water absorption, high viscosity, medium Trace elements (metals) chelating, synergistically slow release and other multiple functions, and 100% biodegradation under natural conditions.
γ-PGA can be widely used in agricultural production materials (fertilizers, pesticides), can significantly retain water, chelate the trace elements, and play a synergistic slow release, improve crop yield and quality.
Super water retention performance, containing more than 1000 -COOH functional groups per molecule of polyglutamic acid (γ-PGA);
The negatively charged free carboxyl group carried by γ-PGA has the ability to adsorb and exchange with the nutrient segregant about 100 times that of natural soil and can effectively prevent the combination of sulfate, magnesium and oxalate in the chemical fertilizer with trace elements such as calcium and magnesium.
Polyglutamic acid (γ-PGA) is a polymer of glutamic acid, which has the properties of acid and alkali, and has excellent buffering ability for acid and alkali;
Polyglutamic acid (γ-PGA) has excellent chelation adsorption capacity for medium and trace elements. Other types of fertilizer synergists, such as polyaspartic acid, which are chemically synthesized, have a small molecular weight and are limited in their functions.
In addition, polyglutamic acid (γ-PGA) and its potentiating fertilizers not only have the effects of slowing down fertilizer loss, drought and water retention, disease resistance and yield increase, etc. compared with similar fertilizer promoters such as polyacrylic acid and polyaspartic acid. Efficacy, and has the advantages of low production cost, superior performance, easy to use and other types of fertilizer synergists.
Polyglutamic acid (γ-PGA) combines the functions of slow release and synergistic effect, and has many excellent characteristics that traditional slow release fertilizer and polyaspartic acid synergistic fertilizer do not possess. Polyglutamic acid (γ-PGA) has a good chelation effect on medium and trace elements.
Polyglutamic acid (γ-PGA) can be used to produce synergistic compound fertilizer based on polyglutamic acid (γ-PGA), which is non-toxic, harmless, residue-free and has strong chelating properties for plant nutrients. Potted and field cultivation of a variety of vegetables, rice, corn, citrus, and tobacco. The field experiment was carried out by rooting or spraying the synergistic compound fertilizer containing polyglutamic acid (γ-PGA). The results showed that the fertilizer consumption and yield increase could be reduced under the premise of improving crop yield and quality.
Polyglutamic acid (γ-PGA) is mainly processed from agricultural and sideline products, and its raw materials are glucose, glutamic acid and citric acid, all of which come from renewable resources. With the improvement of the production process and the improvement of the fermentation level, the production cost of polyglutamic acid will gradually decrease, which will be more conducive to its promotion and application.
Polyglutamic acid is a biodegradable polypeptide macromolecular polymer produced by microbial fermentation. It is non-toxic and safe to eat. (In Japan, Korea, Taiwan and other countries, poly-Y-glutamic acid has been approved as food, Cosmetic additives), in the natural soil environment, can be gradually degraded by microorganisms into glutamic acid required for plant growth, and L-glutamic acid is a precursor of ethephon to promote the growth of crops.
