The results indicated that the optimum concentration of the chemical mutagen-EMS was 0.3%; the optimum induction medium was MS＋6-BA 1.5 mg · L^-1, NAA 0.1 mg · L^-1 and the optimum rooting medium was MS＋0.05 mg · L^-1 NAA.展开更多

The result showed the mutagenic activated sludge had remarkable effect and application potential in pulping wastewater treatment. Comparing with common activated sludge, the mutagenic activated sludge was more suitable for lignose decomposition and had high decomposing efficiency.展开更多
