Experimental investigation and numerical modeling of a cross-linked biopolymer stabilized soil
TL;DR: In this paper, a cross-linked protein biopolymer, polyγ-glutamic acid (γ-PGA), and a polysaccharide biopolymers, β-glucan (β-G), were crosslinked and were adopted for soil stabilization.

Ainhoa Tolentino,Salvador León,Abdelilah Alla,Antxon Martínez de Ilarduya,Sebastián Muñoz-Guerra +4 more
TL;DR: In this paper, stoichiometric ionic complexes of bacterial poly(γ-glutamic acid) with the cationic N-octadecyl and N-docosyl-N, N,N,N-trimethylammonium surfactants were mixed with a modified bentonite to generate hybrid compounds covering a wide range of clay/polymer compositions.

Poly-γ-glutamic acid production by simultaneous saccharification and fermentation using corn straw and its fertilizer synergistic effect evaluation
TL;DR: In this paper, the possibility of Bacillus amyloliquefaciens JX-6 using corn straw as substrate to synthesize poly-γ-glutamic acid (PGA) was validated, and the results showed that increasing the proportion of glucose in the substrate could improve the γ-PGA yield.

Complete Regression of Well-established Tumors Using a Novel Water-soluble Poly(l-Glutamic Acid)-Paclitaxel Conjugate
Chun Li,Dong Fang Yu,Robert A. Newman,Fernando Cabral,L. Clifton Stephens,Nancy Hunter,Luka Milas,Sidney Wallace +7 more
TL;DR: Data suggest that in addition to its role as a carrier for selective delivery of paclitaxel to the tumor, PG-TXL exerts distinct pharmacological actions of its own that may contribute to its remarkable antitumor efficacy.
