ABSTRACT

An anaerobic bacterium was isolated and identified from an anaerobic expanded granular sludge bed reactor (EGSB) that was treating pure terephthalic acid (TA) wastewater. The bacterium could effectively degrade terephthalic acid. The screened anaerobic bacterium was determined to be Bacillus cereus. It could degrade 1000 mg/L TA within 72 h, and the maximum degradation rate was 98%. Its TA degrading enzymes were endoenzymes.

Keywords : Anaerobic degradation, terephthalic acid (TA), screen, identification.
