Maomo ScienceOur toxicity monitoring system uses luminescent bacteria as biosensors to detect the presence of toxic substances in the toxicity detection series products of Modern Water Company. Their ability to detect toxic substances is *.

Biological monitoring technology plays an increasingly important role in acute toxicity assessment. The use of bioluminescent bacteria as biosensors has a history of over 30 years.

ButMicrotox®The biotoxicity detection technology is simple, fast, economical, convenient, and reproducible, and has become one of the recognized biotoxicity determination methods in the world today. Unlike conventional tests that may take up to 96 hours to manually count,Microtox®Results can be provided in less than an hour. And provide fast, accurate, and reliable testing equipment for municipal, industrial, and commercial customers.

As a type of luminescent bacteria,AliiVibrio fischeriIt is a deep-sea bioluminescent bacterium that is very rare in its range and can only be obtained from deep-sea fish. The respiratory process of its bacterial cells is accompanied by natural luminescence, and the luminescence rapidly decreases when exposed to toxic substances, which can be used as an indicator of human and ecological toxicity, and can be measured by photometry.

So in the event of an emergency of water pollution, Vibrio fischeri can serve as a good biosensor to quickly assess the degree of chemical and biological pollution in water samples. The complete set of methods for the cultivation, storage, freeze-drying, quality control, and detection of AliiVibrio fischeri is calledMicrotox®.

Microtox®Method is a method for acute toxicity detection of water quality, which is an emergency toxicity detection system based on biosensing technology. The basis of the measurement method is the use of Vibrio fischeri as a biosensor, which inhibits the normal metabolism of bacteria when toxic substances are present in the environment, resulting in a decrease in bacterial luminescence intensity. The measured indicator, biotoxicity, is a comprehensive indicator that is closely related to the biological characteristics of Vibrio fischeri, a luminescent bacterium.

The comprehensive biological toxicity detected by this method is correlated with the median effect concentration (EC50) in toxicology, which can provide reference for further chronic toxicity research.

Microtox®Toxicity detection technology can detect acute toxicity in water quality, serving as a biological warning and sudden biological toxicity detection device. It has a wide detection range, is sensitive to most organic/inorganic toxic substances, can reflect comprehensive toxicity changes, and is suitable for emergency monitoring and early warning of toxic substance pollution events.
