Microbiological Analysis

Microbiological analysis is the use of biological, biochemical, molecular or chemical methods for the detection, identification or enumeration of microorganisms in a material. It is often applied to disease causing and spoilage microorganisms.
Microbiological Analysis

Microbiological analysis helps to keep under control the proliferation of viruses, bacteria, microorganism which may cause contamination, intoxication and disease.

In order to achieve successful results in the isolation and identification of bacteria we should make sure we use the right water type.

Crucial step in microbiological analysis are:

  • Sampling - Appropriate representative samples are the foundation for reliable and accurate results
  • Filtration - This step is important to enhance microorganism recovery and avoid exogenous contamination
  • Culturing - It is affected by the quality of the growth medium
  • Incubation - The final stage before enumerating microorganism
Impact of water

This procedure uses samples of water and from these samples determines the concentration of bacteria.

Water requirements

Make sure that you are using the right water type for your application. Here are the requirements for microbiological analysis applications.
