Abstract

Monosodium glutamate wastewater (MSGW) is a nutrient cultivation medium for microorganism cultivation because it contains abundant nutrient. The research focused on the cultivation of B. subtilis 168 with MSGW to produce poly (γ-glutamic acid). The optimal cultivation conditions for the production of poly (γ-glutamic acid) by B. subtilis 168 were obtained. Simultaneously, the flocculation performances of culture supernatant and crude γ-PGA were also investigated. Turbidity and active red removal efficiency of crude γ-PGA was about 80% and 55%, respectively.
