室内环境中微生物与挥发性有机化合物相关性的初步探讨

采集室内环境空气中菌落，经培养后分别将微球菌属、葡萄球菌属、芽孢杆菌属、曲霉属、青霉属的纯培养物转接到培养皿上，然后放入环境测试舱密闭环境中进行放大培养。分析菌落放大培养前后环境测试舱内空气中VOCs组成及其含量水平。结果表明，检测的100种挥发性有机化合物中有42种化合物在扩大培养后浓度升高，而30种化合物的浓度下降。微生物在生长代谢过程中既能分解空气中的一些毒害性有机污染物，也能产生一些毒害性有机污染物。

A Preliminary Study on the Relationship Between Microorganism and Volatile Organic Compounds in Indoor Environment

Microorganism was collected from indoor environment and then incubated in an isolating environmental test chamber. The concentrations of the volatile organic compounds in the chamber before and after incubating were determined and compared. The results showed that 42% of the detected compounds represented higher concentrations after incubating while 30% became lower. Thus microor- ganism can decompose some toxic organic compounds in air during its metabolism while at the same time it can release some others...
