Abstract
Biodegradation of acetaldehyde and characteristic analysis of microorganisms in Biological Activated Carbon (BAC) filter were investigated. The results revealed that microorganisms in BAC bed were mainly responsible for the removal of acetaldehyde. Biodegradation efficiency for acetaldehyde was more than 95%. The phylogenetic analysis for the nearly complete sequences of 16S rDNA demonstrated a decrease of the bacterial groups and gene sequences from 13 to 6 and 81 to 33, respectively; whilst the heteotrophic plate count bacteria increased from 1.18×107 CFU/g to 1.28×108 CFU/g. Betaproteobacteria was the predominant bacterial group, 78% of total bacteria while only 11% of those in the sample before acetaldehyde added. A lot of sequences affiliated to Betaproteobacteria, such as SY-10, SY-41, SY-1, SY-75, SY-14, SY-107 which accounted for more than 50% of total clone sequences in the clone library, had high similarity to those originated from similar environment in previous literatures and could assimilate simple organic substances containing one carbon atom. It proved they played a decisive role in the biodegradation process of acetaldehyde and were acetaldehyde degraders.
