Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Bioremediation uses toxin-degrading bacteria to clean up:
A
Gold and silver.
B
Hazardous material.
C
Dirty instruments.
D
Viral infections.
Explanation: 

Detailed explanation-1: -Bioremediation is an eco-friendly process of the degradation of toxic pollutants into nontoxic or less hazardous substances mediated by microbial enzymes. Biodegradation of various hazardous pollutants through the application of different enzymes from bacteria and fungi have been widely studied.

Detailed explanation-2: -Bioremediation is the use of microbes to clean up contaminated soil and groundwater. Microbes are very small organisms, such as bacteria, that live naturally in the environment. Bioremediation stimulates the growth of certain microbes that use contaminants as a source of food and energy.

Detailed explanation-3: -The wi ite rot fungus Phanerochaete chrysosporium has been shown to effectively degrade pollutants such as trichlorophenol, polychlorinated biphenyls (PCBs), dioxins and other halogenated aromatic compounds.

Detailed explanation-4: -Bioremediation is a cost-effective and environmentally tolerable technology that employs a biological process to reduce environmental risks caused by toxic substances and other hazardous pollutants.
