中文摘要：
考察了铜离子浓度对甲烷氧化混合菌群MY9（CGMCCNo.1893）生长和甲烷单加氧酶活性的影响,并对混合菌群中的非甲烷氧化菌进行了分离鉴定和碳源特异性研究.结果表明,甲烷氧化混合菌群MY9能利用甲醇、乙醇、丁醇、异丙醇、甘油等多种非甲烷化合物作为生长碳源,且具有耐高Cu2＋浓度的生长特性.从混合菌群中分离的非甲烷氧化菌Acinetobacter junii No.8能分别以4%甲醇、1%乙醇或0.6%二氯甲烷作为唯一生长碳源,适用于高浓度甲醇废水、乙醇废水或含二氯甲烷废水的生物处理.
英文摘要：
The growth characteristics of a methane-utilizing mixed consortia MY9 （CGMCC No. 1893） were examined with different copper ion concentrations and carbon sources. Some heterotrophs of the mixed consortia were isolated and characterized. The results showed that the mixed consortia could utilize many organic chemicals such as methanol, ethanol, butanol, isopropanol and glycerol as the carbon source as well as methane. It could also grow in the condition of high concentration of copper. One of the heterotrophs isolated from the mixed consortia, identified as Acinetobacter junii No.8, could utilize 4% methanol or 1% ethanol or 0.6%（φ） dichloromethane as a sole carbon source. These results suggest that the methane-utilizing mixed consortia MY9 or A. junii No.8 can be potentially used in the biocatalytical treatment of wastewater containing high concentrations of methanol wastewater, ethanol or dichloromethane.
