Chloramines are widely used to maintain a disinfectant residual in water distribution systems, but can result in nitrification. This research documents the effectiveness of free chlorine for the control of nitrifying bacteria, evaluates the effect of pipe materials on nitrifying bacteria, and determines how DPBs change as a result of the switch to free chlorine.Do not add NP40 if the objective is to determine a spatial distribution of cells in a floc. 2. Fixed cells can be ... Some probes seem to work better when formamide is not included and the hybridization stringency is then regulated by adjusting saltanbsp;...
