Question

A process that uses micro-organisms to convert harmful industrial wastes to less toxic or non-toxic compounds is known as

• A. Complement fixation
• B. Precipitation
• C. Bioremediation
• D. Bioconversion

Answer 1

The correct option is C Bioremediation

Bioremediation or phytoremediation is the cleaning of environment of toxic wastes with the help of microbes, plant and animal species. The organisms involved in bioremediation are of two types: hyperaccumulators and detoxifying species. Hyperaccumulators are used in bioprospecting and removal of minerals from wastes. The detoxifying agents like the microbes metabolise the harmful chemicals through various biochemical reactions.

So, the correct answer is 'Bioremediation'
