However, this polynomial regression model suffered from thecolor metameric problem. Herewith, to minimize the metamerism, a model was developed based on the principal component analysis and back-propagation artificial neural network for scanner spectral characterization, which could reconstruct more accurate spectrum in comparison with the related international experimental results.

The results from the study on the decoloring conditions of strain 3# showed that the pH range for decoloring reaction was 5～11 with 6 ～7 being the optimum, the temperature range was 10～30℃ with 30℃ being efficiency optimal. The decoloring efficiency was higher under the presence of oxygen than that lack of oxygen. Strain 3# could more strongly decolor malachite green under optimum conditions. The decoloring rate was above 50%, 70% and 90% in 4, 12 and 24 h treatment, respectively.
