2. Total viable count - Wikipedia

   en.wikipedia.org/wiki/Total_Viable_Count

   The reported count is the number of colonies counted multiplied by the dilution used for the counted plate A high TVC count indicates a high concentration of micro-organisms which may indicate poor quality for drinking water or foodstuff. In food microbiology it is used as a benchmark for the evaluation of the shelf-life of foodstuffs [1]

3. Bacteriological water analysis - Wikipedia

   en.wikipedia.org/wiki/Bacteriological_water_analysis

   Bacteriological water analysis is a method of analysing water to estimate the numbers of bacteria present and, if needed, to find out what sort of bacteria they are. It represents one aspect of water quality. It is a microbiological analytical procedure which uses samples of water and from these samples determines the concentration of bacteria ...

4. Dip slide - Wikipedia

   en.wikipedia.org/wiki/Dip_slide

   Bacteria present in the sample liquid will grow and form colonies. A bacterial reference chart is used to determine the number of bacteria in the sample. Appropriate treatment is applied to the water source once abnormal levels of bacterial activity are noticed. Once water treatment is effective the bacterial count produced by the dip slide ...

5. Total viable organism - Wikipedia

   en.wikipedia.org/wiki/Total_Viable_Organism

   Total viable organism (or TVO) is a term used in microbiology to quantify the amount of microorganisms present in a sample. [1] Each sample is usually cultured on a variety of agar plates (petri dishes) often containing different types of selective media. The colony-forming units (CFUs) are calculated after allowing time for growth.

6. Colony-forming unit - Wikipedia

   en.wikipedia.org/wiki/Colony-forming_unit

   In microbiology, a colony-forming unit (CFU, cfu or Cfu) is a unit which estimates the number of microbial cells (bacteria, fungi, viruses etc.) in a sample that are viable, able to multiply via binary fission under the controlled conditions. Counting with colony-forming units requires culturing the microbes and counts only viable cells, in ...

7. Plate count agar - Wikipedia

   en.wikipedia.org/wiki/Plate_count_agar

   The total number of living aerobic bacteria can be determined using a plate count agar which is a substrate for bacteria to grow on. The medium contains casein which provides nitrogen , carbon , amino acids , vitamins and minerals to aid in the growth of the organism.
