ENHANCED TREATMENT OF TANNIC ACID SIMULATED WASTEWATER BY A FRACTIONAL FACTORIAL DESIGN USING MIXTURE STRAINS
Statistics-based experimental designs were used to construct a mixed-culture community for maximal degradation of tannic acid in simulated wastewater by six different strains, i.e., Agrobacterium sp., Bacillus sp., Enterobacter cloacae, Gordonia, Pseudomonas stutzeri, and Pseudomonas putida. By applying a fractional factorial design (FFD) of experiments, the significant effect of each strain on tannic acid degradation was analyzed, and three strains were verified to be effective for the degradation of tannic acid. A quadratic model was found to be fit for tannic acid removal efficiency. Validation experiment showed that predicted value of model and testing values have no significant difference. Immobilized strains can further increase tannic acid removal efficiency to 85.6 %.
