Abstract

A bacterial strain able to degrade terephthalic acid (TPA) was isolated and identified to belong to the Corynebacterium sp. It was named Corynebacterium sp. YT-14. When stirred loop bioreactor was used in a batch type system for removing terephthalic acid from weight loss treatment wastewater and complex dyeing process wastwater, the removal efficiency of terephthalic acid was 85.4% after 7 days of treatment of the weight loss treatment wastewater, while no residual terephthalic acid was detected after 3 days of treatment of the complex dyeing process wastewater

1. TPA 제거능이 우수한 미생물을 개발하였으며 동정 결과 Corynebacterium sp. 로 판단되며 Corynebacterium sp. YT-14로 명명하였다. 2. TPA 제거를 위한 Corynebacterium sp. YT-14의 최적 배양온도는 $35^{\circ}C$ 였고, 최적 초기 pH는 pH 10이었다. 3. Stirred loop bioreator에 Corynebacterium sp. YT-14를 배양한 후 감량가공폐수와 종합염색폐수를 회분식으로 처리한 결과 감량가공폐수에서 처리 7일 후 TPA 제거효율이 85.4% 였으며, 종합염색폐수에서는 처리 3일 후 TPA가 검출되지 않았다.
