| Sumario: | [EN] Excessive growth of filamentous bacteria causes bulking and foaming in activated sludge wastewater treatment plants (WWTP). One of the most common bacterial group responsible of these operational problems is known as Nostocoida limicola morphotype. The different ecophysiology of bacteria that represent N. limicola, especially those that are found within N. limicola II, suggests that the measures corrective to control the exccesive growth can be different. Therefore, the conventional identification might place lead to a wrong decision in the WWTP. The main aim of this study was to identify and estimate the abundance of the different species of N. limicola II in three WWTP from the Comunidad Valenciana (Spain) using the fluorescence in situ hybridization technique (FISH). The results have enabled us to determine their frequency depending on the different variables of the process control, suggesting that the identification of N. limicola II with the conventional technique would be unsuitable for further decision making in the WWTP, being the most appropriate the FISH technique. |
