Abstract A rapid, precise and accurate microtiter most-probable-number (MPN) procedure has been developed and tested for simultaneous (two reagent addition) enumeration of denitrifier and nitrate reducer populations in an agricultural soil. Values from 0.12 × 10 6 to 0.22 × 10 6 denitrifiers g −1 soil were determined using two concentrations of ...

Decoding the MPN principle: Clarifying the logical structure of most probable number estimation
Journal of Microbiological MethodsThe Most Probable Number (MPN) method is widely used for estimating viable microbial concentrations from dilution-based presence-absence data obtained from inoculated culture units. Although commonly presented as a statistical procedure derived from the Poisson distribution, its logical structure includes an initial deterministic interpretive component.

Nontyphoidal Salmonella (NTS) is a relevant pathogen involved in gastroenteritis outbreaks worldwide. In this study, we determined the capacity to combine the most probable number (MPN) and multiplex polymerase chain reaction (PCR) methods to characterize the most important Salmonella serotypes in raw sewage. A total of 499 isolates were recovered from

[Application effect of most probable number (MPN) method in photosynthetic bacteria counting].
Ying yong sheng tai xue bao = The journal of applied ecology, 2007The application of most probable number (MPN) method in counting the numbers of photosynthetic bacteria (PSB) showed that this method was suitable for PSB counting under illumination and anaerobic condition, which remedied the shortages of other methods.

Continuous European Union programmes with specified methods for enumeration of Escherichia coli in bivalves for human consumption are currently running. The objective of this research was to examine the species accuracy of the five times three tube Most Probable Number (MPN) EU reference method used for detection of E. coli in marine bivalves.

We developed a sensitive quantitative assay for detecting Ralstonia solanacearum in soil by most probable number (MPN) analysis based on bio-PCR results. For development of the detection method, we optimized an elution buffer containing 5 g/L skim milk for extracting bacteria from soil and reducing contamination of polymerase inhibitors in soil ...

Estimating bacterial concentrations in food products is a key element in quantitative microbial risk assessment (QMRA). A Bayesian probabilistic approach with the most probable number (MPN) technique was developed to estimate the concentration of Salmonella in chicken meat based on the qualitative data.
