Abstract:A dominant strain (named W-2) which can utilize fluorene as carbon and energy source for growth was isolated and screened from activated sludge of a coking plant. On the basis of morphological observation and physio-biochemical test, the strain W-2 was identified as Stenotrophomonas acidaminiphila by 16S rDNA gene sequence and phylogeny analysis. The biodegradation efficiency of fluorene by strain W-2 (S. acidaminiphila) in solution culture was further investigated. Results indicated that the strain could effectively degrade fluorene and the biodegradation efficiency reached 86.0% after 11 days under the conditions of initial fluorene concentration 40mg/L, inoculation amount 10% (V/V), pH 7.0 and temperature 30℃. The results showed that strain W-2 had a good application prospect in control of fluorene pollution.
