Abstract
The overall objective of this study is to develop the engineering-friendly-methodology which can investigate the fate of antibiotic resistance in environment microbial community. For this purpose, effective concentration (EC) concept was adopted with cultural based method which is currently used in engineering practice. When a tetracyline antibiotic was present as selective pressure agent among microbial community, activated sludge, the $EC_{50}$ and/or $EC_{90}$ of tetracycline in microbial community were statistically increased compared to control, especially higher growth rate and organic loading conditions of SBRs. Therefore, these results strongly suggested that the continuous monitoring of EC in microbial community can be used for characterizing the fate of tetracycline resistance community in environmental samples.
