TBC Microbial Test
Bacteriological analysis of water is a method for estimating the number of bacteria present in a unit volume and, if necessary, for finding the type of bacteria, the level of interpretation and performance of which varies for different waters depending on the use of the water. By counting within certain time limits, the rate of bacterial multiplication and its spread can be determined.
Fast, accurate and sensitive counting of bacterial populations in the natural environment is an essential task for many research fields.
Total bacterial count (TBC) is performed with various techniques and methods to determine the number of bacteria present in water and wastewater samples. For unicellular microorganisms, such as bacteria, cell reproduction of all organisms is constantly taking place. Therefore, microbial growth is essentially synonymous with microbial reproduction. So, to determine the growth rate and mortality of microbes, it is necessary to perform a TBC test.
What is TBC?
The TBC (Total Bacterial Count) of a substance is a quantitative estimate of the number of microorganisms present in a sample. This measurement is expressed as the number of colony forming units (CFU) per gram (or milliliter) in the sample. In fact, the total bacterial count is also known as the total viable bacterial count (TVC).
TBC and Microbial Corrosion Induced (MIC):
TBC is one of the most important factors influencing the formation of microbial corrosion. (MIC) The higher the number of bacteria, the greater the likelihood of MIC occurring.
While wastewater naturally consists of high concentrations of microorganisms, bacteria can be present in almost all water and wastewater systems. As these organisms grow, they attach themselves to wet surfaces and form thin, slippery films, also known as biofilms.
The higher the total bacterial count in water or wastewater, the more bacteria are present in the fluid and the thicker the biofilm that forms. Bacteria in biofilms feed on nutrients in water or wastewater and produce corrosive gases that can attack metal surfaces.
By measuring the total number of bacteria in liquids, various methods can be used to control the bacterial population and thereby reduce the effects of MIC.
*The laboratories of Abrizan Industrial Research Company, located in Fars Science and Technology Park, are capable of measuring a variety of water parameters, including TBC testing, with experienced staff and the use of advanced devices and equipment.
