Frontiers in Bioengineering and Biotechnology, 2020 The production of poly-γ-glutamic acid (γ-PGA), a biopolymer consisting of D- and L-glutamic acid monomers, currently relies on L-glutamate, or citrate as carbon substrates. Here we aimed at using plant biomass-derived substrates such as xylose.

Dual-layered nanogel-coated hollow lipid/polypeptide conjugate assemblies for potential pH-triggered intracellular drug release. [PDF]
PLoS ONE, 2014 To achieve effective intracellular anticancer drug delivery, the polymeric vesicles supplemented with the pH-responsive outlayered gels as a delivery system of doxorubicin (DOX) were developed from self-assembly of the lipid/polypeptide adduct, distearin

Bacillus subtilis natto: a non-toxic source of poly-γ-glutamic acid that could be used as a cryoprotectant for probiotic bacteria [PDF]
, 2013 It is common practice to freeze dry probiotic bacteria to improve their shelf life. However, the freeze drying process itself can be detrimental to their viability.

Advanced Science, EarlyView.A neutrophil‐membrane‐camouflaged nanoplatform (RC@NMVs) exploits tumor inflammation to target and accumulate in tumors. Intracellular Ca2+ overload is triggered via lysosomal CaP dissolution and Ru red‐mediated Ca2+ channel blockade, synergistically inducing gasdermin‐mediated pyroptosis.

Poly-γ-Glutamic Acid Attenuates Angiogenesis and Inflammation in Experimental Colitis
Mediators of Inflammation, 2013 Poly-γ-glutamic acid (γ-PGA), naturally secreted from various strains of Bacillus, has anti-inflammatory activity. In inflammatory bowel disease (IBD), inflammation is promoted and sustained by angiogenesis; however, the role played by γ-PGA in this ...
