Microbial gas-sensing property of Escherichia coli with mixed metal catalyst MgFe sub(2)O sub(4)

A thick biofllm of Escherichia coli was applied to a mixed metal catalyst, MgFe sub(2)O sub(4) synthesized using solution combustion technique. The isolated pure culture of E. coli was mixed with the prepared mixed metal catalyst. Both preparation processes were convenient, environment-friendly and...

Summary:A thick biofllm of Escherichia coli was applied to a mixed metal catalyst, MgFe sub(2)O sub(4) synthesized using solution combustion technique. The isolated pure culture of E. coli was mixed with the prepared mixed metal catalyst. Both preparation processes were convenient, environment-friendly and efficient. The MgFe sub(2)O sub(4) materials were characterized by TG/DTA and XRD. The prepared thick biofilm of E. coli with MgFe sub(2)O sub(4) was measured by exposing to different reducing gases. It was found that E. coli acted as a sensor and showed various responses to different gases at various operating temperatures with metal catalyst. The prepared biofilm sensor exhibited fast response and good recovery at low concentration.
