Chlorpyrifos degradation in a biomixture of biobed at different maturity stages

► We evaluated different maturity stages of the biomixture of biobed. ► Effect of the maturity stages of the biomixture on chlorpyrifos degradation and biological activity were evaluated. ► TCP formation was also evaluated. ► In all time of maturity stages evaluated pesticide was degraded, but decreased with increasing concentrations. ► When the time of maturity increased, greater accumulation of TCP in the biomix occurred.
