【摘要】 【目的】为了从细胞水平上了解泉水细菌群落对有感地震的映震规律及敏感菌群的代谢特征。【方法】基于2012年1月31日至12月31日,震中距乌鲁木齐10号泉100公里范围内的5次有感地震,利用平板培养计数和BIOLOG GEN III细菌板监测地震前后泉水中细菌群落活性及代谢功能多样性变化。【结果】泉水细菌群落全年呈现随机动态变化,震后可培养细菌菌落数目和细菌群落碳源利用的平均颜色(Average well color development,AWCD)变化高于震前,且表现与震级具有一定相关性;泉水中对有感地震有响应的灵敏细菌群以糖醇类碳源为主要代谢碳源。【结论】本研究初步证实了GEN III细菌板能用于泉水细菌群落代谢功能多样性的研究。细菌群落的碳源利用及可培养菌落数目具有一定映震规律。更多还原

【Abstract】 [Objective] Our aim was to know response of spring bacteria and metabolic characteristics of sensitive bacteria to felt earthquake.[Methods] Water samples were collected from January 31 to December 31,2012,during which period 5 felt earthquakes occurred and the epicenter was 100 kilometers away from the No.10 Spring in Urumqi.We monitored the spring bacterial activities and function diversity changes from No.10 Spring in Urumqi during the pre- and post-earthquake stages by using plate culture counting methods and BIOLOG GEN III bacteria plate.[Results] The spring bacterial numbers presented stochastic dynamic changes through the year.The culturable bacteria numbers and average well color development( AWCD) of carbon source utilization of bacterial community were higher after the earthquake.Besides,there were some correlations with magnitude and epicenter distance of earthquake.The main carbon source utilization types of sensitive bacteria group for felt earthquake were sugar alcohol at the No.10 Spring.[Conclusion]The results indicated that the BIOLOG GEN III plate can be used for spring bacterial metabolism diversity research.Culturable bacteria numbers and carbon source utilization of bacterial communities showed some reflecting earthquake law.更多还原
