Abstract—In order to improve the biodegradability of xanthate, province. A synthetic xanthate wastewater was used in the
the biodegradation process of butyl xanthate as the sole source of research with the ponents: xanthate 50 mg/L,
carbon and energy pared to that with an external carbon K2HPO4 g/L, KH2PO4 g/L, MgSO4 g/L, CaC12 1
source added. The experimental results showed that the mg/L, NH4Cl g/L. The pH value was .
degradation rate of xanthate was significantly increased in the
co-metabolism process. The biodegradation rate of butyl C. Method of anism Acclimation
xanthate was % after shaking culture for 72 hours under the Under the conditions of 25℃ and 130r/min, a 250 mL
following conditions: constant temperature of 25 ℃, external conical flask was oscillated on the airbath oscillator, and the
glucose as growth substrate with a concentration of . conical flask was filled with a certain amount of media
While using butyl xanthate as the sole source of c
