摘要：
The simultaneous removal of atrazine and nitrate in continuous culture under denitrifying conditions using Pseudomonas sp. strain ADP was investigated. Under all operational conditions the nitrate removal efficiency was always higher than 90%, while atrazine degradation deteriorated with time due to contamination by foreign denitrifying bacteria, lacking the ability to degrade atrazine. Recovery of atrazine degradation ability was achieved by applying aerobic conditions with atrazine as the sole nitrogen source. (C), 2001 Elsevier Science Ltd. All rights reserved.
