Polyglutamic Acid Powder

 

Polyglutamic acid powder(PGA) is a water-soluble, biodegradable and non-toxic polymer.

 

Polyglutamic acid is the main component of natto viscous colloid, which has the effect of promoting mineral absorption.

 

Due to the special molecular structure of polyglutamic acid, it has a strong moisturizing ability. Adding polyglutamic acid to cosmetics or skin care products can effectively increase the moisturizing ability of the skin and promote skin health.

 

The moisturizing ability of polyglutamic acid is 2-3 times that of hyaluronic acid (HA).

1. Agricultural efficiency improvement and ecological restoration

(1) Soil improvement

• Water retention performance: The water absorption rate reaches 5,000 times, which increases the corn emergence rate by 42% in arid areas.
• Slow-release fertilizer: After compounding with NPK, the nitrogen utilization rate increases from 30% to 58%.
• Heavy metal passivation: By complexing soil cadmium (Cd²⁺) with carboxyl groups, the cadmium content in rice is reduced by 67%.

 

(2) Crop stress resistance

• Induces systemic resistance: Upregulates SOD and POD enzyme activities, reducing wheat yield loss by 29% under salt stress.
• Cold resistance mechanism: polyglutamic acid powder can increase the proportion of unsaturated fatty acids in cell membranes.

 

2. Biomedical innovative applications

 

(1) drug delivery system

• pH-responsive nanoparticles: drug release efficiency in tumor microenvironment (pH 6.5) reaches 92% (DOX drug loading capacity 18%).
• Cross-blood-brain barrier carrier: After modification with brain-targeting peptide, the brain concentration of doxorubicin increased 8.7 times.

 

(2) Antibacterial and anti-inflammatory

• Inhibit Staphylococcus aureus biofilm formation (MBIC₅₀=128μg/mL).
• Downregulates the NF-κB pathway and reduces TNF-α secretion by 73% (LPS-induced macrophage model).

 

3. Daily chemical and food industry innovation

 

(1) Skin care technology

• Super moisturizing: skin moisture loss rate is only 9% in 48 hours.
• Anti-photoaging: polyglutamic acid powder can inhibit the expression of MMP-1.

 

(2) Food processing

• Cryoprotectant: Increases the water-holding capacity of shrimps by 28% after thawing.
• Prebiotic function: Promote the proliferation of bifidobacteria.

 

4. Breakthroughs in environmental management technology

(1) Sewage treatment

• Heavy metal adsorption: The maximum adsorption capacity of Pb²⁺ reaches 489mg/g.
• Oil-water separation membrane: Flux 380L/(m²·h) and no performance degradation after 20 cycles.

 

(2) Carbon neutral materials

• Biodegradable packaging film: 92% soil degradation rate in 28 days.
• Carbon dioxide storage: Each ton of γ-PGA fixes 0.82 tons of CO₂.
