| Research Abstract |
In this research project, to develop a magnetic biosensor for specific pollutant detection, magnetotactic bacteria was investigated, because of their activity of magnetic particle production. Here we evaluated minimum inhibitory concentration (MIC) and magnetite productivity profiles of the magnetotactic bacteria grown in the presence of various transition metal ions and metalloid oxyanion. As a result, the highest doping of Co, Mn and Cu in bacterial magnetite were successfully found and the MIC profiles were also metal ion dependents. In addition, magnetic measurements of these bacteria grown in different condition revealed the difference of the magnetic property. Based on these information, a prototype of microbial biosensor system has been fabricated. Using the results and information in this study, novel biosensing system for highly specific detection of pollutant will be developed in near future.
