Journal of Experimental Marine Biology and Ecology, 1998 A series of experiments was carried out to determine the accuracy and reproducibility of the most probable number (MPN) technique for estimating concentrations of viable planktonic diatoms from sediment samples. Two contrasting species were used to inoculate sterilised sediments: Ditylum brightwellii (large single-celled species) and Skeletonema ...

Angka Paling Mungkin (Most Probable Number/MPN) Coliform Sampel Kue Bingke Berendam di Pontianak [PDF]
Protobiont: Jurnal Elektronik Biologi, 2019 Bingke berendam cake is one of the traditional foods of Pontianak which is made from rice flour, eggs, sugar and coconut milk. Materials that are used such as sugar, milk and eggs are ingredients that are easily damaged and polluted by microbes. This study aimed to to find out the Most Probable Number (MPN) of coliform bacteria in bingke cakes.

Qualitative Analysis of Drinking Water Through the Most Probable Number (MPN) Method
Stamford Journal of Microbiology, 2015 Water borne disease outbreaks associated with the drinking of unsafe water, containing pathogenic bacteria of fecal origin, is common in densely populated countries like Bangladesh. Present study was attempted to detect indicator bacteria from drinking water samples for the presumptive occurrence of fecal contaminations that are responsible for health ...

Enumeration of Specific Populations by the Most-Probable-Number (MPN) Method
1979The most-probable-number (MPN) method of bacteria enumeration dates back to the earliest days of bacteriology. Despite drawbacks of the method, it offers a relatively simple and useful means of estimating microbial populations, especially for determining the physiological potential of microbial biomass.

Biocontrol Science, 2009 The purpose of this study was to evaluate the most-probable-number dilution plate (MPN plate) method developed for the enumeration of Escherichia coil in water samples. Sterilized water was inoculated with E. coli ATCC 11775 to give between 2-1600 MPN/100 ml. The MPN was determined for both the MPN plate and 5-tube methods from the MPN table.

Estimation of methane-producing bacterial numbers by the most probable number (MPN) technique
Water Research, 1967Abstract Heukelekian and Heinemann proposed a method in 1939 of enumerating the methane-producing bacteria that occur in anaerobic digesters. A modification of their method is presented here which is simpler to use and yields more consistent results.

A Most Probable Number (MPN) method was developed allowing for the first time estimation of populations of bacteria capable of heterotrophic nitrification. The method was applied to an acidic soil of a coniferous forest exhibiting nitrate production.

Most probable number (MPN) and colony-forming-unit (CFU) estimates of fecal coliform bacteria concentration are common measures of water quality in coastal shellfish harvesting and recreational waters. Estimating procedures for MPN and CFU have intrinsic variability and are subject to additional uncertainty arising from minor variations in experimental

The standard Bacteriological Analytical Manual (BAM) protocol for detecting Listeria in food and on environmental surfaces takes about 96 h. Some studies indicate that rapid methods, which produce results within 48 h, may be as sensitive and accurate as the culture protocol. As they only give presence/absence results, it can be difficult to compare the

Determination of sulfur and iron oxidation bacteria by the most probable number (MPN) technique
1999The number and the activity of acidophilic bacteria present in bioleaching processes is one of the most important parameters to understand the behaviour of a leaching process. The most frequently isolated species from these ecosystems are strains of Thiobacillus ferrooxidans, Leptospirillum ferrooxidans and Thiobacillus thiooxidans .
