ATP - Bioluminescence as a technique to evaluate the microbiological quality of water in food industry



Brazilian Archives of Biology and Technology 47(3): 399-405

A TP-bioluminescence was used to evaluate the microbiological quality of water samples collected from the water supply, the water treatments system and from a dairy plant, including ammonia-cooling water and industrial water. For industrial water, there was relation between the A TP-bioluminescence technique and microbial count. There were no differences (p>0.05) between water supply and ammonia-cooling water samples for total and free ATP concentrations nor for the microbial counts. Different microbial ATP concentrations were found for these water samples. The results suggested that the physical chemical quality of ammonia cooling water decreased the RLU measurements slightly. It could be concluded that the total ATP concentration was the most effective technique to evaluate the microbiological quality of water used in the food indsutry by ATP-bioluminescence.
