Acinetobacter baumannii TRP5去除人工合成廢水中二乙胺之研究

Removal of Diethylamine from Synthetic Wastewater by Acinetobacter baumannii TRP5

摘要


二乙胺為醫藥、農藥、橡膠、塑膠、聚合物等工業中常用之有機物質,該物質有臭味、可能會導致癌症,且經微生物分解後可能會產生氨氮,故含有二乙胺之廢水若未經妥善處理就予以放流,對整個生態環境會造成重大影響。故本研究之目的希望能利用生物方法,獲得可去除二乙胺之純種菌株,並瞭解該菌株對人工合成廢水中二乙胺的去除情況。研究結果顯示,菌株TRM1、TRM7、TRP1、TRP2、TRP4-1、TRP4-3、TRP6、TRP7-1及TRP7-2皆無法利用二乙胺生長;菌株TNM3、TRM2、TRP3及TRP4-2,雖部份顯示可利用二乙胺生長,但生長情形並不明顯;而菌株TRP5則可利用二乙胺生長。此外,菌株Acinetobacter baumannii TRP5對人工合成廢水中600 mg/l以下之二乙胺有100%去除率。

Diethylamine is used widely in industry and can be found in many commercial applications. In order to avoid the wastewater that produces after diethylamine using effects the water quality, endangering public health and welfare, the study aim attempted to remove diethylamine by the biological method. The results reveal that strain TRM1, TRM7, TRP1, TRP2, TRP4-1, TRP4-3, TRP6, TRP7-1 and TRP7-2 could not utilize DEA for growth; Strain TNM3, TRM2, TRP3 and TRP4-2 could utilize 200 mg/l DEA for growth, but the strain dry weight value increasing amount was not apparent. Strain TRP5 could utilize 200 mg/l DEA for growth and the strain dry weight value increasing amount was apparent. Besides, Acinetobacter baumannii TRP5 could use 600 mg/l diethylamine for growth from synthetic wastewater in a batch reactor and the diethylamine removal efficiency could reach 100%.
