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.
