Bio-methane potential (BMP) testing is a standard anaerobic lab test used to assess the methane production potential of different feedstocks in wastewater treatment systems. This testing can be applied pretty much universally for anaerobic sites, including mixed systems, lagoons (though sampling here can be a major hurdle), and UASBs. While BMP testing procedures can vary by site, the key points ...
As winter approaches, many wastewater operators have already begun increasing their solids retention time to prevent the loss of nitrification in the winter. Overall, this makes a lot of sense, as nitrifiers have a slow growth rate and metabolism. However, there is a major shortfall to holding more solids going into the winter. Higher MLSS or MLVSS does not mean more active bacteria in all ...
Cold temperatures and biocides are two things that often cause challenges for wastewater operators. While on their own, both challenges can typically be managed through plant operation. However, if both of these stressors are impacting a system at the same time, will their impacts combine to create an epic wastewater catastrophe? ...
It is based on the assumption: Total ATP – free ATP = intracellular ATP Intracellular ATP is deduced from the measurement of total and free ATP. ...
While culture method only measures culturable bacteria, i.e., the ones able to grow on a given media, ATP testing measures the quantity of ATP in a sample. As this molecule is produced and found in all living bacteria, ATP testing measures all the bacteria, culturable or not. ...
As a powerful tool for the qualitative and quantitative study of small molecules (metabolites) in biological samples, metabolomics has become a major tool for annotating gene functions and revealing various endogenous physiological and biochemical reactions produced by cells after exogenous stimuli in various research fields, including life sciences, disease diagnosis, drug development, ...
In order of sensitivity, enzymatic analysis, ATP measurement, and flow cytometric fingerprinting were the most performant for detection of rain- and groundwater contaminations (0.01 – 0.1 v%). ...
The objective of this study, which was carried at microLAN company in Waalwijk (NL) and supported by HWL (Het Water Laboratorium, Haarlem, NL), is to validate the results obtained from the BACTcontrol biosensor by comparing the ALP activity with different common water analysis like ATP and Flow Cytometry that are regularly used to assess water ...

Adaptation tipping points (ATPs) refer to the situation where a policy or management strategy is no longer sufficient, and adjustments or alternative policies/strategies have to be considered. In developed countries, the main focus of research has been on characterising the occurrence of ATPs in the face of slow variables like climate change. In developing countries, the system ...
The comparisons between flow cytometry (FCM) and other cultivation-independent methods (adenosine tri-phosphate (ATP) analysis for bacteria enumeration and epifluorescence microscopy (EFM) for virus enumeration) gave very similar patterns of microbial abundance changes, suggesting that FCM is suitable for targeting and obtaining reliable counts for bacteria and ...
In order to achieve these goals, a methodology for the exergetic analysis of metabolism is presented. The exergy value of the metabolic compounds takes into account the compounds concentration in the environment, ionic dissociations, metal compounds formation, ionic forces and electric potential. The electric potential represents an important aspect and must be considered in any ...
The objective of the present study was to evaluate the usefulness of bioluminescence measurement and analysis of swabs taken from the surfaces of the equipment for determination of the hygienic state of a milking machine when biofilm is present on the surfaces. ...
