Employing living cells as biosensor – an unspecific early warning system for contaminations – unravels natural environment questions.

Environmental Monitoring

With algae as signal converters the systems can be used to monitor water quality.

The example shows the reduced photosynthetic activity of chlorella kessleri after contamination with Metamitron and their recovery after removal of the herbicide.


Food Testing

To check if food is free of toxins a probe of the food or the washing water can be investigated.

The example shows the reduced vitality of yeast due to a fungicide.


Risk Assessment

New ingredients of daily products like cosmetics or detergents have to be classified in their harmlessness as well as in their degradabillity and exposure time.

The example shows the oxygen consumption rate of cells after treatment with different concentrations of an unknown substance.
