Our partner company MOCON now sell and market the GreenLight™ 900 series globally. The GreenLight™ range of food safety tests provide easy, same-day detection and enumeration of bacteria in food samples by measuring bacterial oxygen consumption (bacterial respiration) and equating oxygen consumption to microbial load.

As bacteria in the test sample grow and respire they deplete O2 which is detected as an increase in the GreenLight™probe signal above the baseline level. The time required to reach this increase in signal is used to calculate the cfu/g of the food sample, based on a pre-determined calibration.
