| 中文摘要 |
| 为了筛选降解苯系化合物的优势菌种,选用城市污水处理场和石化废水处理场的活性污泥作为菌源,分别以甲苯、乙苯、邻二甲苯、间二甲苯、对二甲苯、1,3,5-三甲苯作为底物。在好氧条件下,驯化、筛选和分离出了能以上述6种比合物作为生长的唯一碳源和能源的微生物25株,并对其进行了初步的鉴定。这些菌株的好氧生物降解研究结果表明,它们对苯系比合物具有良好生物降解能力。 |
| 英文摘要 |
| In order to sift for bacteria of degrading benzene homologue compounds,25 strains degrading toluene, ethylbenzene,o-m-and p-xylene and trimethylbenzene were isolated by selective enrichment from activated sludges of petrochemical and municipal wastewater treatment plants. The strain species are able to degrade the benzene homologue compounds as the sole source of carbon and energy. The results indicated that most of the 25 strains have strong capability of biodegra ding benzene homologue compounds under aerobic condition. |
