Psychrotrophic vs. total bacterial counts in bulk milk samples
e objective of the study was to determine psychrotrophic bacteria counts (PBC) and total bacterial counts (TBC) in bulk milk samples collected during a longer period (1999 to 2000). Two sets of samples were analysed. Set 1, including samples collected in three herds, was analysed by the Central Laboratory at České Budějovice. TBC was determined using the apparatus Bactoscan, and PBC by culture...
متن کاملMeasurement of radium micro-precipitates using alpha spectrometry and total alpha counting methods
Background: This study consists of two parts. The first part deals with both qualitative and quantitative analysis of 226Ra using alpha spectrometry measurement method. In the second part, the percentage of radioactive equilibrium between 226 Ra and its daughter products were determined by alpha spectrometry and total alpha measurement system after elapsed time of 15 days from precipitation. Ma...
متن کاملGermination of single bacterial spores.
Changes in refractility and optical density occurring in individual spores of Bacillus cereus T and B. megaterium QM B1551 during germination were investigated by use of a Zeiss microscope photometer. The curves revealed that the germination process in single spores had two distinct phases; an initial rapid phase was followed by a second slower phase. Under the experimental condition employed, ...
متن کاملMethods of destroying bacterial spores
The spores of Bacillus spp. are found widely distributed in nature, which may cause contamination of the environment and eventually diseases to humans and animals. The formation of the bacterial spore is a sophisticated mechanism by which some bacteria remain viable inadequate when subjected to survival stress such as lack of nutrients. The spores are highly resistant to heat, radiation, variou...
