Identification and application of physical and chemical parameters to predict indicator bacterial concentration in a small Californian creek.
This study of Aliso Creek in California aimed to identify physical and chemical parameters that could be measured instantly to be used in a model to serve as surrogates for indicator bacterial concentrations during dry season flow. In this study, a new data smoothing technique and ranking/categorizing analysis was used to reduce variation to allow better delineation of the relationships between adopted variables and concentrations of indicator bacteria. The ranking/categorizing approach clarified overall trends between physico-chemical data and the indicators and suggested sources of the bacteria. This study also applied a principle component regression model to the data. Although the model was promising for predicting concentrations of total and fecal coliforms, it was somewhat weaker in predicting enteroccocci

Distribution of Nitrobacter and Nitrospira Communities in an Aerobic Activated Sludge Bioreactor and their Contributions to Nitrite Oxidation
ABSTRACT An analysis of nitrite-oxidizing bacteria in the activated sludge process of a full-scale partially nitrifying wastewater treatment plant revealed Nitrospira and Nitrobacter averaged 10 13 cells·L -1 and 10 12 cells·L -1 , respectively. Correlation coefficients linking shifts in NOB community to operational or environmental variables illustrated Nitrospira were negatively correlated to nitrite (r = -0.45, P<0.01), while Nitrobacter showed no significant relationship to nitrite (P=0.1017). Nitrospira was negative correlation to DO (r = -0.46, P<0.01) and positively correlated to temperature (r = 0.59, P<0.0001). However, Nitrobacter was positively correlated to DO (r = 0.38, P<0.01) and HRT (R = 0.33, P<0.05), as well as negatively correlated to temperature (r = -0.49, P<0.001) suggesting niche adaptations within the NOB community. The positive association between Nitrobacter and DO supports a selective advantage over Nitrospira in completely nitrifying plants. Given the operational schematic at this WWTP, Nitrospira contributed more to nitrification than Nitrobacter in this WWTP
