“…ATP is used as primary energy sources currency by all organisms. There are significant amounts of knowledge about the ecological and physiological significance of ATP and oxygen consumption (Velten et al, 2007). Plasmid DNA has been used for a long time microbial physiological and biochemical studies (O'Mahony et al, 2005).…”

“…On the other hand, the placement of PS reactors directly after an ozonation treatment exposes the reactors to an increased content of easily degradable organic carbon (34), which is likely to stimulate bacterial growth. Moreover, it is common knowledge that most granulated filter materials that come into contact with drinking water (e.g., sand, anthracite, and active carbon) sooner or later become colonized by a variety of indigenous bacteria (16,32). Notably, the bacteria colonizing such materials are not merely opportunistic but perform an essential biofiltration function in the treatment process through the removal of biodegradable organic matter (12,25,32).…”

Pellet softening reactors are used in centralized and decentralized drinking water treatment plants for the removal of calcium (hardness) through chemically induced precipitation of calcite. This is accomplished in fluidized pellet reactors, where a strong base is added to the influent to increase the pH and facilitate the process of precipitation on an added seeding material. Here we describe for the first time the opportunistic bacterial colonization of the calcite pellets in a full-scale pellet softening reactor and the functional contribution of these colonizing bacteria to the overall drinking water treatment process. ATP analysis, advanced microscopy, and community fingerprinting with denaturing gradient gel electrophoretic (DGGE) analysis were used to characterize the biomass on the pellets, while assimilable organic carbon (AOC), dissolved organic carbon, and flow cytometric analysis were used to characterize the impact of the biological processes on drinking water quality. The data revealed pellet colonization at concentrations in excess of 500 ng of ATP/g of pellet and reactor biomass concentrations as high as 220 mg of ATP/m 3 of reactor, comprising a wide variety of different microorganisms. These organisms removed as much as 60% of AOC from the water during treatment, thus contributing toward the biological stabilization of the drinking water. Notably, only a small fraction (about 60,000 cells/ml) of the bacteria in the reactors was released into the effluent under normal conditions, while the majority of the bacteria colonizing the pellets were captured in the calcite structures of the pellets and were removed as a reusable product.

“…Por isto, é considerado um parâmetro adequado para a quantificação da biomassa ativa em sistemas biológicos. A análise do ATP requer um equipamento analí-tico simples, é rápida e tem limite de detecção baixo (VELTEN et al, 2007). Foi descrito por Velten et al (2007) , 2004;BOON et al, 2011;LAUTENSCHLAGER et al, 2013;ORIOL et al, 2013).…”
