Microbial production of poly-γ-glutamic acid.
Poly-γ-glutamic acid (γ-PGA) is a natural, biodegradable and water-soluble biopolymer of glutamic acid. This review is focused on nonrecombinant microbial production of γ-PGA via fermentation processes. In view of its commercial importance, the emphasis is on L-glutamic acid independent producers (i.e. microorganisms that do not require feeding with the relatively expensive amino acid L-glutami...
متن کاملSelf-Healing, Self-Assembled β-Sheet Peptide–Poly(γ-glutamic acid) Hybrid Hydrogels
Self-assembled biomaterials are an important class of materials that can be injected and formed in situ. However, they often are not able to meet the mechanical properties necessary for many biological applications, losing mechanical properties at low strains. We synthesized hybrid hydrogels consisting of a poly(γ-glutamic acid) polymer network physically cross-linked via grafted self-assemblin...
متن کاملBiosynthesis and Hydrolysis of Poly ( 7 - glutamic acid ) from BaciUizs
Poly(7-glutamic a id) (PGA) production ill Bacillas suhtitis IF03335 was studied. When citric acid as a carbon source was added to a glutamic acid medium containing L-glutamic acid and ammonium sulfate, a large amount of pure PGA wEs produced. On the other hand, when glucose was added to the glutamic acid medium, a by-preduct was produced, which seemed to be a polysaccharide. Moreoyer, the mode...
متن کاملCommentary on Succinic Acid and Poly-γ-glutamic Acid Production using Lignocellulosic Waste Biomass
Lignocellulosic biomass, which contains cellulose (40-50%), hemicellulose (25-50%) and lignin (10-40%), is the most abundantly available raw material on Earth [1]. Broadly, it is classified into three categories: virgin biomass, waste biomass and energy crops. Owing to the rapid growth of global population and corresponding agricultural activities, the amount of lignocellulosic waste biomass is...
متن کاملEffect of Green Tea Extract/Poly-γ-Glutamic Acid Complex in Obese Type 2 Diabetic Mice
BACKGROUND The increasing prevalence of type 2 diabetes mellitus (T2DM) is associated with the rapid spread of obesity. Obesity induces insulin resistance, resulting in β-cell dysfunction and thus T2DM. Green tea extract (GTE) has been known to prevent obesity and T2DM, but this effect is still being debated. Our previous results suggested that circulating green tea gallated catechins (GCs) hin...
