Metabolic engineering of Bacillus amyloliquefaciens for poly-gamma-glutamic acid (γ-PGA) overproduction
We constructed a metabolically engineered glutamate-independent Bacillus amyloliquefaciens strain with considerable γ-PGA production. It was carried out by double-deletion of the cwlO gene and epsA-O cluster, as well as insertion of the vgb gene in the bacteria chromosome. The final generated strain NK-PV elicited the highest production of γ-PGA (5.12 g l(-1)), which was 63.2% higher than that ...
متن کاملPoly-γ-Glutamic Acid (PGA)-Producing Bacillus Species Isolated from Kinema, Indian Fermented Soybean Food
Kinema, an ethnic fermented, non-salted and sticky soybean food is consumed in the eastern part of India. The stickiness is one of the best qualities of good kinema preferred by consumers, which is due to the production of poly-γ-glutamic acid (PGA). Average load of Bacillus in kinema was 10(7) cfu/g and of lactic acid bacteria was 10(3) cfu/g. Bacillus spp. were screened for PGA-production and...
متن کاملMicrobial 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 کاملSynergistic effects of agonistic costimulatory antibodies adsorbed to amphiphilic poly(γ-glutamic acid) nanoparticles
Agonistic antibodies targeting costimulatory pathways for the immune system hold great potential for cancer immunotherapy. However, systemic administration of immunoactivating antibodies can be associated with side effects such as cytokine release syndrome and liver toxicity. Polymeric nanoparticles (NPs) represent an exciting approach to control the release of therapeutic antibodies and to opt...
متن کاملBacterial-Derived Polymer Poly-γ-Glutamic Acid (γ-PGA)-Based Micro/Nanoparticles as a Delivery System for Antimicrobials and Other Biomedical Applications
In the past decade, poly-γ-glutamic acid (γ-PGA)-based micro/nanoparticles have garnered remarkable attention as antimicrobial agents and for drug delivery, owing to their controlled and sustained-release properties, low toxicity, as well as biocompatibility with tissue and cells. γ-PGA is a naturally occurring biopolymer produced by several gram-positive bacteria that, due to its biodegradable...
