| 中文摘要 |
| 从受污染土壤中筛选出具有广谱脱色的优势菌17株,并进一步扩大染料范围,筛选出3株对偶氮、蒽醌、三苯甲烷染料均有较好脱色效果的优势菌株. 3株菌分别为青霉属(菌Ⅰ、菌Ⅱ)和头孢霉属(菌Ⅲ)的真菌;以染料配水为例,探讨了pH值、温度、碳源、氮源因素对菌株脱色的影响;并进行了实际废水的脱色实验,结果表明该菌在pH值5～9, 温度18～37℃的区间内,且外加葡萄糖提供0.5%碳源时对染料废水的脱色率可达70%. 因此对处理染料污染废水具有较好的应用前景.

| 英文摘要 |
| Seventeen strains with wideranging decolorization ability were screened from contaminated soil and were applied on the decoloring of dye wastewater. Three strains were selected due to their high decolorization capacity on azo dyes, anthraquinone dyes and triphenylmethane dyes. The three strains were named as Strain Ⅰ, Strain Ⅱ , Strain Ⅲ .This three superior strains were identified as penicillium link (Strain Ⅰ & strainⅡ ) and Cephalosporium corda (strain Ⅲ). Using aqueous samples, the influences of several factors on decolorization were reported, such as pH, carbon source, temperature and so on. And then applying of these strains for treatment of actual wastewater have also been done. The results showed that the optimal pH, temperature and carbon source were 5～9, 18～37℃ and 0 5% respectively, under those conditions the decolorization removal rate was 70%. And these fungi have a good prospect for the treatment of dye wastewater. |
