NOVELTY - Recycling dimethyl amide from waste biological flocculant of oxidized graphene involves collecting fermentation broth of Enterococcus fecalis and Enterococcus saccharominimus. The Enterococcus fecalis fermentation broth is centrifuged to obtain first supernatant. The Enterococcus saccharominimus fermentation broth is centrifuged to obtain second supernatant and the mycelium is removed. The first and secobd supernatant is centrifuged and dried at 4 degrees C to obtain dry products. The dry products are mixed in the weight ratio (1.5-3):1 to get desired product. USE - Method for recycling dimethyl amide from waste biological flocculant of oxidized graphene (claimed). ADVANTAGE - The method enables to recycle dimethyl amide from waste biological flocculant of oxidized graphene in a eco-friendly, which has high flocculating rate, good thermal stability, and obvious recycling effect.
