摘要

The aim of this work was to obtain a microbial consortium from the effluent of cassava flour production and to investigate its potential for biological treatment of this effluent. Experiments were carried out in a bioreactor with the effluent in the presence of ammonium sulfate at 28 - 30 oC, 1 vvm and 200 rpm. Three pulses of the effluent were weekly added to the bioreactor after seven days of cultivation. The nutrient concentrations of the effluent stimulated the growth of the autochthon microorganisms. The maximum growth of bacteria in the microbial consortium reached 108 CFU/mL at the stationary growth phase. Maximum activity of amylases, cellulases, lipases and proteases were detected after seven days of cultivation. The biodegradation of organic material by the microbial consortium was confirmed by the reduction of the chemical oxygen demand (80 %) and cyanide (28 %) during the biological treatment of the effluent. The microbial consortium obtained from the effluent from cassava flour production has potential on the biodegradation of the industrial effluent.
