CONTAMINANT IDENTIFICATION IN WATER BY MICROBIAL BIOSENSORS – A REVIEW

Abstract

The various micro-organisms are used to identify contaminated water. By the help of biosensors,

drinking water pollution can be estimated. Rising environmental pollution is badly affecting water.

Drinking contaminated water causes serious diseases in human beings as well as in animals.

Microorganism in contaminated water can spread serious diseases. Biosensors are genetically

modified to identify the occurrence of heavy metals, chemicals and toxins in contaminated water.

Different microbes are used as biosensors such as Escherichia coli, Algae, Fungi and Clostridium

etc. All these biosensors help to detect water pollution by different ways. For example, algae can

detect water contamination by fluorescence during photosynthesis. Most rural areas are being

affected by contaminated water. Most of the people living in rural areas are being affected by the

polluted water as clean water is not available in these areas. People living in rural areas use water

that looks clear but contains micro-pathogens that can cause dangerous diseases. Biosensors are

important for identifying contamination, Due biosensor, can easily deduct pollution. Water is very

important for the survival. Drinking contaminated water can cause serious illness. Therefore, clean

water is very important.
