CHEMOMETRICAL STUDIES ON MIXTURE ANALYSIS WITH A SINGLE DYNAMIC MICROBIAL SENSOR

A bacterial pure culture of Alcaligenos eutrophus KT02 was immobilized and integrated as a sensor in an amperometrical flow-through system ( 'dynamic microbial sensor'). The sensor showed characteristic time dep endent responses in oxygen consumption for different pure organic anal ytes. Chemometrical data analysis revealed that the responses are addi tive and linear concerning single analytes and mixtures, Simultaneous multicomponent analysis of a binary mixture of acetate and gluconate w as realized by using only a single dynamic microbial sensor.
