【摘要】 从印染厂污水中筛选到７株高效脱色菌，其中Ｐｓｅ４、Ｐｓｅ２９两菌在非固定化条件下，分别对１０ｍｇ／Ｌ阳离子桃红ＦＧ、活性艳红Ｋ－２ＢＰ溶液在染料为唯一碳源、能源时，１２ｄ脱色８０％以上．这２菌都属于假单胞菌属．将各菌等量混合进行脱色，没有协同作用．采用凹凸棒粘土颗粒或塑料环为载体固定化脱色菌，能大大缩短反应时间，提高脱色率．凹凸棒颗粒固定化柱在６ｈ即对６０ｍｇ／Ｌ混合染料脱色９１％，是一种具有较高实用价值的固定化技术．更多还原

【Abstract】 Seven strains were isolated from the drainage of wastewater treatment plant of a textile factory. Each of these strains can decolor different dye in dye containing water.For example, Pse 4 and Pse29 could decolor more than 80% of the dye Basic Red 13 and the Reactive Red respectively in 12 days when 10mg/L dye in solution was used as sole source of carbon and energy for bacteria. These two strains belong to Pseudomonas.There were no conjunctive function when 7 strains were simply mixed for decolor of mixed dyes in water.However, these strains seem to cooperate effectively when they were immobilized on Attapulgus or plastic rings. Immobilized microbe on Attapulgus can decolor 91% of 60mg/L mixed dyes in 6h. It is supposed to be a good immobilization technology for practical use.更多还原
