Abstract:
Abstract Five strains of bacteria, with decoloring capability for malachite green, were is olated from the activated sludge of dyeing wastewater treatment pond. Among them, strain 3#, Ochrobactrum anthropi, was demonstrated with best decoloring capability. 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. Fig 4, Tab 3, Ref 15
