Microsensors as a tool to determine chemical microgradients and bacterial activity in wastewater biofilms and flocs

Microsensors used in microbial ecology are reviewed with emphasis on new sensor developments (NO3-, NO2-, NH4+, CO2, H2, H2S and CH4 microsensors as well as fiberoptical microsensors for O2, temperature and pH). Examples of microsensor applications in biofilms and activated sludge flocs are presente...

Zusammenfassung:	Microsensors used in microbial ecology are reviewed with emphasis on new sensor developments (NO3-, NO2-, NH4+, CO2, H2, H2S and CH4 microsensors as well as fiberoptical microsensors for O2, temperature and pH). Examples of microsensor applications in biofilms and activated sludge flocs are presented, in which sulfate reduction and denitrification were studied.
