Microbial life is of major importance for the functionality of ecosystems. In aquatic systems, the assessment of bacterial activity is a key criterion for the evaluation of substance-induced effects. At Noack, bacteria studies with both aerobic and anaerobic species can be conducted to meet your substance registration requirements.
… from different sources
Activated sludge is used for studies investigating the inhibition of respiration and nitrification (ASRIT).
Anaerobic digester sludge is used for investigating the inhibition of anaerobic bacteria.
Both sludge types originate from local sewage treatment plants and the quality is closely monitored.
Studies on luminescent bacteria are performed with Allivibrio fischerii in fresh water or seawater. For more detailed information about our marine testing portfolio, please refer to the Marine Ecotoxicity section.
…in different conditions.
Studies on aerobic bacterial toxicity are conducted as respiration inhibition tests (ASRIT), with or without the determination of the inhibition of nitrification (acc. to OECD 209).
Tests specific for the inhibition of nitrification are done in activated sludge (acc. to DIN EN ISO 9509), studies on inhibition of anaerobic bacteria activity in digester sludge (acc. to OECD 224). Luminescent bacteria tests (acc. to DIN ISO 11348) are performed with Allivibrio fischerii.
All our studies can be conducted under GLP and are supported by a broad range of experience in scientific work on a variety of different compound classes. We strive for complete transparency and a close communication during the course of your studies. Monthly status updates, guaranteed testing slots and real-time updates are only some examples of our customer service.
