MARA is a unique, innovative product for use in toxicity testing.   It is highly versatile and can cope with a wide range of samples ranging from complex industrial effluents to potable water.

The test consists of an array of eleven genetically diverse micro-organisms (ten bacteria and one yeast), freeze-dried in a micro-titre plate. The array is exposed to either a concentration gradient of the test sample or an undiluted sample.  Growth of the micro-organisms in the array is measured by recording the reduction of a redox dye through the use of a flat bed scanner and image analysis software.

MARA meets all the required test criteria for micro-scale ecotoxicity tests:

- simplicity                                      - sensitivity
- speed                                           - accuracy
- reproducibility                             - standardisation
- precision                                     - cost effectiveness
- convenience

In addition to the above, MARA provides the user with significantly more information which is not available from other tests:

- data for 11 test results (provided by a ‘battery of tests’ within a test)
- minimum and maximum concentration values across the range of micro-organisms
- can be used to produce toxic fingerprints
- indicative of the mode of action of chemicals and toxicants
- indicative of the similarity between chemicals and toxicants
- can be used to produce a dendrogram comparing unknown chemicals to standards

NCIMB will be running regular training workshops on the use of the MARA product.  For further information, please email mara@ncimb.com or contact us either via our enquiry form or by using the other contact details listed here.
