Microbial production and functional assessment of γ-polyglutamic acid isolated from Bacillus sp. M-E6 [PDF]

Frontiers in Microbiology
This study describes the production and functional evaluation of γ-polyglutamic acid (γ-PGA) synthesized by Bacillus sp. M-E6, isolated from a traditional fermented food. Among 103 isolates screened, strain Bacillus sp.

Identification of Key Metabolites in Poly-γ-Glutamic Acid Production by Tuning γ-PGA Synthetase Expression [PDF]

Frontiers in Bioengineering and Biotechnology, 2020
Poly-γ-glutamic acid (γ-PGA) production is commonly achieved using glycerol, citrate, and L-glutamic acid as substrates. The constitutive expression of the γ-PGA synthetase enabled γ-PGA production with Bacillus subtilis from glucose only. The precursors

Study on the mechanism of production of γ-PGA and nattokinase in Bacillus subtilis natto based on RNA-seq analysis [PDF]

Microbial Cell Factories, 2021
Poly-γ-glutamic acid (γ-PGA) and nattokinase (NK) are the main substances produced by Bacillus subtilis natto in solid-state fermentation and have wide application prospects. We found that our strains had higher activity of nattokinase when soybeans were

Construction of an engineered Bacillus subtilis for production of poly-γ-glutamic acids with specific molecular weights [PDF]

Frontiers in Microbiology
IntroductionPoly-γ-glutamic acid (γ-PGA) with different molecular weight (Mw) exhibits different properties and therefore has a variety of applications. At present, the γ-PGA is mainly produced by Bacillus species.

Poly-Gamma-Glutamic Acid (γ-PGA)-Based Encapsulation of Adenovirus to Evade Neutralizing Antibodies. [PDF]

Molecules, 2018
In recent years, there has been an increasing interest in oncolytic adenoviral vectors as an alternative anticancer therapy. The induction of an immune response can be considered as a major limitation of this kind of application.

A circular bioprocess application of algal-based substrate for Bacillus subtilis natto production of γ-PGA [PDF]

Frontiers in Chemistry, 2023
Poly-γ-glutamic acid (γ-PGA) is a bio-derived water-soluble, edible, hydrating, non-immunogenic polymer. Bacillus subtilis natto is a wild-type γ-PGA producer originally isolated from Japanese fermented natto beans whose activity has been shown to be ...

Effects of poly-γ-glutamic acid (γ-PGA) on plant growth and its distribution in a controlled plant-soil system [PDF]

Scientific Reports, 2017
To demonstrate the responses of plant (Pakchoi) and soil to poly-γ-glutamic acid (γ-PGA) is essential to better understand the pathways of the promotional effect of γ-PGA on plant growth. In this study, the effects of γ-PGA on soil nutrient availability,
