Analysis of Variable Fractions Resulting from Microbial Counts

Quantitative Microbiology, 1999
In microbiological studies various methods are employed to estimate fractions from paired counts of organisms. When the fraction (second count divided by first count) is constant among the paired counts, the maximum likelihood estimate is the ratio of the arithmetic means.

Storage of soils for direct microbial counts

Plant and Soil, 1972
The application of a number of standard storage techniques to a mull soil and millipede faeces resulted in significant changes in microbial populations measurable by a haemocytometer counting method.

Cell counting and carbon utilization velocities via microbial calorimetry

Biotechnology and Bioengineering, 1990
AbstractBacteria rapidly metabolize sugars and produce heat accordingly (Escherichia coli, aerobic conditions, 25°C). Two kinds of heat output are gotten: (1) from excess cells and limiting carbon, 2 × 109 to 5 × 109 cells, 5‐50 nanomole glucose; (2) from limited cells and excess carbon, 0. 1 × 109‐1 × 109 bacteria and 200‐600 nmol glucose.

Impact of microbial count distributions on human health risk estimates

International Journal of Food Microbiology, 2015
Quantitative microbiological risk assessment (QMRA) is influenced by the choice of the probability distribution used to describe pathogen concentrations, as this may eventually have a large effect on the distribution of doses at exposure. When fitting a probability distribution to microbial enumeration data, several factors may have an impact on the ...

Soil microbial counts in relation to site characteristics at a subantarctic Island

Microbial Ecology, 1982
Enumerations of colony-forming units of aerobic bacteria and fungi at Marion Island (46°54'S, 37°45'E) showed that the mire and bog peats investigated possessed greater numbers of microorganisms on a dry soil weight basis than did the slope fernbrake soils but that counts from both sites were similar per unit soil volume.

[The microbial count of insulin multiple-dose containers].

Die Pharmazie, 1991
In accordance with the Pharmacopoeia of the GDR, from multiple-dose containers containing injection preparations with preservatives added such preparations may be repeatedly withdrawn up to 72 h after opening these containers. Exempted from this limitation are multiple-dose containers containing insulin injection preparations repeatedly used by ...

Stochastic Considerations on the Upper and Lower Limits of Colony Counts on Agar Plate for Microbial Count Calculation

Food Hygiene and Safety Science (Shokuhin Eiseigaku Zasshi)
The upper and lower limits of microbial colony count on agar plate are essential for microbial cell calculation of food samples. In the present study, the limits presented by the three standards of Ministry of Health, Labor, and Welfare of Japan, Food and Drug Administration of US (FDA), and Japanese Industrial Standards (JIS) were studied from the ...
