Microbiological analyzes carried out by authorized laboratories within the scope of cleaning and disinfection analyzes are carried out for very different purposes and with different methods. Some of these analyzes are purely chemical analysis. Some of them are difficult and even dangerous enough to be performed by qualified and experienced microbiologists.

Different methods of microbiology are used in various branches of microbiology in the search for the presence of a certain microorganism in a substance brought to the laboratory for testing and analysis.

Microorganism search analyzes usually focus on two objectives:

• The presence of pathogens is generally investigated in food, environmental and clinical substances, including cleaning agents.
• In the field of industrial microbiology, on the contrary, high quality isolates are tried to be obtained.

The first creatures on Earth are microbes, that is microorganisms. While humans have only existed on Earth for a million years, microorganisms have been on Earth for a billion years. Today, the science of microbiology is too large to be collected under one roof. The main branch of general microbiology is divided into various sub-departments such as food microbiology, veterinary microbiology, clinical microbiology, agricultural microbiology and industrial microbiology. Industrial microbiology and related biotechnology are among the most important disciplines today.

Microorganisms are small organisms that cannot be seen with the eye. The best known are bacteria, molds, yeasts and algae. However, microorganisms can multiply from one cell to millions and become colonies. In this case, they create visible structures. Molds formed in planting are the best examples of this.

There are estimated to be around 6 million different types of microorganisms on Earth, but not all of them have been identified.

Some microorganisms are found in acidic environments, some in neutral environments and some in basic environments.

Some laboratories are accredited according to the standards of TS EN ISO / IEC 17025 General Conditions for the Competence of Testing and Calibration Laboratories from domestic and foreign accreditation organizations and carry out microbiological analysis studies. These laboratories operate in accordance with test methods and test criteria accepted worldwide. In addition, test, measurement, analysis and evaluation studies are based on many standards published by national and international organizations. These laboratories provide reliable and impartial services, and analyzes and reports are accepted all over the world.

Within the scope of microbiological analyzes, the following analysis studies are mainly carried out in laboratories:

• Total aerobic mesophilic bacteria count
• Total coliform count
• Total yeast and mold count

Total aerobic mesophilic bacteria counts are performed in cosmetics, detergents and cleaning chemicals along with foods. However, very special devices and very special analysis methods are required for total bacterial counting. In the standard analyzes, the number of bacteria obtained under aerobic or anaerobic conditions is determined. Aerobic mesophilic bacteria count is a widely used and easy-to-perform quality standard.

The coliform group, which is a very complex group, has a high number of bacteria. These bacteria are bacteria that develop under anaerobic conditions and do not form spores. When coliform bacteria are mentioned in food technology, Escherichia coli (E. coli) is the leading one. They are not allowed in foodstuffs. Total coliform counts are made in cosmetic products, detergents and cleaning chemicals as well as drinking and using water and foods. It is important that the water used in detergent production is clean and will not cause problems for human health.

 

Total yeast and mold counts are among the basic analyzes conducted primarily for food products. However, total yeast and mold counts are made in cosmetic products, detergents and cleaning products in order not to cause any danger to human health.
