title: Recovery of protein from discharged wastewater during the production of chitin.
abstract: Studies were carried out to optimize the conditions for the recovery of protein. The results showed that pH of 6.00 for wastewater, the dosage of 1% chitosan solution in 1% acetic acid aqueous solution of 2.0 ml for 50 ml wastewater and 1% FeCl(3) aqueous solution of 2 ml for 5 0ml wastewater, the flocculation time of 4.0 h were the optimal conditions for the recovery of protein. The obtained protein sediment contained abundant amino acids, especially isoleucine, methione and lysine that are absent in other protein resource.
