摘要
为了了解日偏食对空气微生物群落碳代谢的影响,利用BIOLOG指纹图谱方法分析日偏食前后乌鲁木齐空气微生物群落碳代谢功能多样性的变化。结果表明,日偏食当天空气微生物的碳源代谢能力高于其他几天。微生物群落多样性指数方差分析显示,当天(2009年7月22日)Shannon-Wiener多样性指数最高;主成分分析表明对碳源利用起分异作用的主要是羧酸类物质。日偏食会影响乌鲁木齐空气微生物群落功能多样性。
The aim of this study was to investigate the effect of partial solar eclipse on the carbon metabolic diversity of airborne microorganisms. We used Biolog metabolic fingerprinting method to analyze the variation of the carbon metabolic diversity of airborne microbial community in Urumqi before and after partial solar eclipse. The results suggested that the ability of carbon sources utilization for microbes on the day was higher than other days. The analysis of variance of the microbial community diversity indices showed that Shannon-Wiener diversity was the highest on the day; and principal component analysis demonstrated that carboxylic acids was the mainly carbon sources to the differentiation of the airborne microorganisms. Hence partial solar eclipse may affect the functional diversity of air microbial community in Urumqi.
