Abstract
An alkaliphilic Dietzia sp., strain GS-1, which degraded disodium terephthalate (DT), was isolated from soil. Strain GS-1 degraded 19.3 mM of DT in 168 h at pH 10. The maximum degradation velocity was 0.46 mM/h. The resting cells efficiently degraded 28.7 mM of DT in 51 h at 28 degrees C and pH 10. The degradation velocity was 0.41 mM/(h g-wet cell).
摘要
从土壤中分离出一株嗜碱Dietzia菌，菌株GS-1，它能降解对苯二甲酸钠（DT）。菌株GS-1在pH 10条件下168小时内降解了19.3 mM的DT。最大降解速度为0.46 mM/h。静止细胞在28℃和pH 10条件下51小时内有效降解了28.7 mM的DT。降解速度为0.41 mM/（h·g湿细胞）。
