Bacterial Enumeration Methods Used in Microbiology
Abstract
Bacterial enumeration methods are used in the microbiology to determine the amount of bacterial growth in a sample of water, food, beverage and pharmaceutical product to determine its quality. The purpose of these series of experiments is to enumerate bacteria using the pour plate method, the membrane filtration method and the most probable number method. Escherichia coli (E. coli) in tryptic soy broth were used as the bacteria source in the experiments. A bacterial count of 1.29 x 108 was calculated using the pour plate method, the membrane filtration method yielded a bacterial count of 1.14 x 108 and the most probable method yielded a bacterial count of 1.1 x 108. The three...
The end:
.....e methods produced similar results within the 1.0 x 108 to the 1.3 x 108 range. The highest bacterial count of 1.29 x 108 was calculated using the pour plate method, the membrane filtration method yielded a bacterial count of 1.14 x 108 and the most probable method yielded a bacterial count of 1.1 x 108. The most probable method is the least accurate method because it does not involve an actual bacterial count but provides an estimate of the bacterial count using the turbidity and the values from a table.
