Production optimization of poly-γ-glutamic acid by Bacillus amyloliquefaciens under solid-state fermentation using soy hull as substrate

Poly-γ-glutamic acid (PGA) is a biodegradable polymer with wide applications in the field of medicine, cosmetics, food and agriculture. The aim of the present work was to develop a microbial method to produce PGA under solid-state fermentation. Soy hull was used as the solid media in fermentation by...
