Bacterial poly-gamma-Glutamic Acid (y-PGA) - a promising biosorbent of heavy metals [PDF]
, 2015 Poly-γ-glutamic acid (γ-PGA) is a biopolymer made up of repeating units of L-glutamic acid, D-glutamic acid or both. γ-PGA is water soluble, non-toxic and biodegradable, and can be used safely in a variety of applications that are increasing rapidly ...

Shuitu Baochi Xuebao, 2020 为了明确一种新型的环保型保水缓释剂γ-聚谷氨酸（简称γ-PGA）的节水保肥效应，在施氮量相同情况下（2 g/kg）设置了4种γ-PGA梯度的施加量（0，0.1%，0.2%，0.4%），以0作为对照处理，通过室内一维土柱入渗试验，研究了γ-PGA施加量对土壤氮素迁移特性的影响。结果表明：（1）定水头入渗条件下，累积入渗量、入渗速率、湿润锋迁移的距离均随着γ-PGA施量的增加而逐渐越小，与对照组相比，添加0.4%γ-PGA的试验组其累积入渗量、入渗率和湿润锋迁移的距离分别减少27.64%，73.45%，31.

Shuitu Baochi Xuebao, 2018 为进一步探究γ-聚谷氨酸在农业方面应用，将不同γ-PGA含量（0，0.1%，0.2%，0.5%，1%）施入无团粒结构的砂壤土与粉壤土中，研究了γ-PGA在土壤物理结构及持水特征方面的作用。结果表明：随γ-PGA含量的增加，同一吸力下土壤持水量增加，VG模型中参数α值均大于对照组，n值递减。γ-PGA添加至1%时，砂壤土中容重降低0.087 g/cm3，孔隙度增加3.28%，粉壤土中容重降低0.108 g/cm3，孔隙度增加4.08%，添加γ-PGA降低了毛管孔隙比例，提高无效孔隙比例，表明γ ...
