Characterization and Growth Optimization of a Novel Salt Resistant Pseudomonas putida Strain Zm Capable of Degrading Trichloroethylene by Cometabolism Under Aerobic Conditions 作者:Zhang, X (Zhang, X.)[ 1 ] ; Xu, D (Xu, D.)[ 2 ] ASIAN JOURNAL OF CHEMISTRY 卷: 25 期: 15 頁(yè): 8718-8722 子輯: A 出版年: NOV 2013 查看期刊信息 摘要 A novel toluene-oxidizing strain capable of cometabolizing trichloroethylene was isolated and characterized. Combined with 16S rRNA sequence analysis, it was identified as Pseudomonas sp. It could grow with toluene as the sole carbon source. The analysis of the growth curve showed that Zm could reach the logarithmic phase within 8-10 h. Continuous sampling showed that toluene was exhausted within 1 d. Finally 29.1 % of trichloroethylene (50 mg/L) can be removed after incubation in mineral salt medium in the presence of 200 mg/L toluene for 3 d and 62.7 % for 7 d. The optimization of growth conditions was also conducted, the optimal growth conditions as the follows: carbon source toluene, at the concentration of 200-400 mg/L, medium pH 7, temperature 28 degrees C and shaking speed 200 rpm. The tested strain Zm also showed substantial salt resistance including at 3.5 % NaCl concentration, indicating the potential application in bioremediation of coastal and marine trichloroethylene contaminants. 關(guān)鍵詞 作者關(guān)鍵詞:Aerobic cometabolism; Biodegradation; Pseudomonas putida; Trichloroethylene; Salt tolerance KeyWords Plus EGRADATION; BIODEGRADATION; TOLUENE; TCE; F1作者信息 通訊作者地址: Zhang, X (通訊作者) Yancheng Teachers Univ, Jiangsu Prov Key Lab Coastal Wetland Bioresources, Yancheng 224051, Peoples R China. 地址: [ 1 ] Yancheng Teachers Univ, Jiangsu Prov Key Lab Coastal Wetland Bioresources, Yancheng 224051, Peoples R China [ 2 ] Yancheng Teachers Univ, Coll Life Sci & Technol, Yancheng 224051, Peoples R China 電子郵件地址:yongshengzh@163.com 基金資助致謝 基金資助機(jī)構(gòu) 授權(quán)號(hào) National Natural Science Foundation of China 10905035 Jiangsu Provincial Key Laboratory of Coastal Wetland Bioresources and Environmental Protection Jiangsu Key Laboratory for Bioresources of Saline Soils 查看基金資助信息 出版商 ASIAN JOURNAL OF CHEMISTRY, 11/100 RAJENDRA NAGAR, SECTOR 3,, SAHIBABAD 201 005, GHAZIABAD, INDIA 類(lèi)別 / 分類(lèi) 研究方向:Chemistry Web of Science 類(lèi)別:Chemistry, Multidisciplinary 文獻(xiàn)信息 文獻(xiàn)類(lèi)型:Article 語(yǔ)種:English 入藏號(hào): WOS:000325204200110 ISSN: 0970-7077 期刊信息 Impact Factor (影響因子): Journal Citation Reports® 其他信息 IDS 號(hào): 228RF Web of Science 核心合集中的 "引用的參考文獻(xiàn)": 18 Web of Science 核心合集中的 "被引頻次": 0 |
