The toxicity effects of methyl tert-butyl ether (MTBE), tert-butyl alcohol (TBA) and formaldehyde (FA) on indigenous
microbial community in forest soil were studied. MTBE, TBA and FA with different concentrations were added
into microcosms containing forest soil samples. After 10 and 30 days, total viable cell number and dehydrogenase activity
in the microcosms were evaluated. Bacterial communities in the microcosms were also analyzed using a denaturing
gradient gel electrophoresis (DGGE). Dehydrogenase activity and total viable cell number were decreased according to
the increase of MTBE, TBA and FA concentrations (P<0.05). FA toxicity was the the highest, and TBA toxicity was
the lowest. The results of principal component analysis using DGGE fingerprints showed that the microbial communities
contaminated with MTBE, TBA and FA were grouped by exposure time, but not by exposure concentration.
Dominant species in the microcosms were as follows: gamma-proteobacteria, Chloroflexi, Actinobacteria, Clostridia
and Bacilli f or M TBE, TBA a nd FA.
