APPLICATION OF A LINEAR ALKYLBENZENE SULFONATE BIOSENSOR TO RIVER WATER MONITORING

A novel whole cell biosensor was constructed for the detection of anio nic surfactants in aquatic environments, The analysis was rapid, conve nient and did not require organic reagents. In this report, the applic ation of this sensor to river water samples was investigated when appl ied to environmental samples; other organic substances present in rive r water may affect the measurement of linear alkylbenzene sulfonates, In order to deal with this problem, a correction system was developed using whole cells of Trichosporon cutaneum. This system was applied to in situ 24 h continuous monitoring in the Saka river. (C) 1998 Publis hed by Elsevier Science S.A. All rights reserved.
