Resumo: ATP-bioluminescence was used to evaluate the microbiological quality of water samples collected from the water supply, the water treatment system and from a dairy plant, including ammonia-cooling water and industrial water. For industrial water, there was relation between the ATP-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.

Nas águas, foram efetuadas, também, as contagens de mesófilos aeróbios, expressos em UFC.mL-1 e coliformes totais, expressos em NMP.100 mL-1. Foi utilizado um luminômetro para os testes de determinação de ATP total e livre, expressos em Unidades Relativas de Luz (URL), nas diversas águas. O ATP microbiano foi determinado pela diferença entre o ATP total e livre. Em relação à água industrial, houve a concordância entre os métodos de bioluminescência e de contagem de mesófilos aeróbios e coliformes totais. As amostras de água de manancial e de resfriamento não apresentaram diferença (p>0,05), pelo teste de Tukey, para as quantidades de ATP total, livre e também para as contagens microbianas. Constataram-se concentrações diferentes de ATP microbiano para essas amostras de água. Os resultados indicam que o teste de ATP total é o mais recomendado para avaliar a qualidade microbiológica da água e sugerem que a qualidade físico-química da mesma pode afetar a formação de luz.Brazilian Archives of Biology and Technology2019-07-02T12:55:37Z2019-07-02T12:55:37Z2000-07info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlepdfapplication/pdf16784324http://dx.doi.org/10.1590/S1516-89132004000300010http://locus.ufv.br//handle/123456789/26020engv.47, n. 03, p. 399- 405, jul. 2004Costa, Patrícia DolabelaAndrade, Nélio José dePassos, Frederico José VieiraBrandão, Sebastião César CardosoRodrigues, Carolina Gonçalves Freireinfo:eu-repo/semantics/openAccessreponame:LOCUS Repositório Institucional da UFVinstname:Universidade Federal de Viçosa (UFV)instacron:UFV2024-07-12T06:08:42Zoai:locus.ufv.br:123456789/26020Repositório InstitucionalPUBhttps://www.locus.ufv.br/oai/requestfabiojreis@ufv.bropendoar:21452024-07-12T06:08:42LOCUS Repositório Institucional da UFV - Universidade Federal de Viçosa (UFV)false
