Contaminants in food and feed



The research at the Department of Chemistry and Bioengineering at Tampere University of Technology aims at the development of sustainable technologies for bioprocess industry and related topics. Dr. Matti Karp has developed during his research career several kinds of bioreporter applications based on light-emitting microbial cells. The reporter systems are applied for the detection of heavy metals, antibiotics, toxic substances and endocrine disrupters. The overall description for the activities of the department may be found at: http://www.tut.fi/public/index.cfm?mainsel=17585&sel=17585&Show=29611&siteid=185&CFID=12008324&CFTOKEN=59367525


TUT has expertise in development and validation of living bacterial “tools” for main heavy metals or metalloids that use heavy metal responsive elements and reporter genes leading to light emission by the sensor cell as a dose dependent function of a metal. He has experience in development of methods to permanently store the sensor cells that are to be used as ordinary reagents as well as in development of biomolecular cell free detection methods based on recombinant metal binding regulatory proteins. He works in fundamental research on novel detection methods using molecular biotechnology approaches. He is involved in collaborations to commercialize the sensor cells.
