A novel Method for the selective recovery and purification of γ-polyglutamic acid from Bacillus licheniformis fermentation broth

Microbially produced gamma‐polyglutamic acid (γ‐PGA) is a commercially important biopolymer with many applications in biopharmaceutical, food, cosmetic and waste‐water treatment industries. Owing to its increasing demand in various industries, production of γ‐PGA is well documented in the literature...
