Water is one of the indispensable resources in our life. Nowadays, with the rapid development of industry and agriculture in all aspects, water pollution has become a topic of concern. If you want to understand the changes in water quality, detecting microorganisms in water is one method. So, do you know about microbial detection in water? It doesn’t matter if you don’t know. In this article, the editor will learn about the issue of microbial testing in water together with everyone.

Why is it Necessary to Test for Microorganisms in Water?

Because in our daily life, if the microorganisms in water are not effectively detected, it will cause some health problems. For instance, in the food industry, there are various sources of microorganisms in water. One of them is fecal contamination of water bodies, which leads to the spread of intestinal infectious diseases and causes certain harm to the human body. Also, if there are too many microorganisms in the water body, it will cause excessive growth of algae, resulting in insufficient oxygen in the water and leading to the death of fish and shrimp due to lack of oxygen.

How can we Detect Microorganisms in Water?

The parameters for microbial detection in water are not limited to just one type. Therefore, it is still necessary to determine which parameters to test based on the water quality conditions. Among them, there are several common pathogenic ones, such as coliform bacteria, Escherichia coli, and total colony count, etc. The main purpose of detecting such parameters is to prevent excessive microorganisms from affecting water quality.

There are two methods for detecting microorganisms in water: multi-tube fermentation method and enzyme substrate method. The online coliform bacteria analyzer produced by Hangzhou Modi uses the enzyme substrate method. It observes the content of coliform bacteria in water by the color presented in the culture medium based on the substances decomposed by the β2 enzyme produced by microorganisms.
