Bioremediation is a process of detoxifying or degrading contaminants present in the soil, wastewater, or industrial sludge by biological means. Microorganisms (bacteria, fungi, etc.) can take part in this process, although plant-assisted bioremediation is often termed as phytoremediation. Aerobic bacteria are mostly used in new treatment plants in what is known as an aerated environment. This bacterium uses the free oxygen within the water to degrade the pollutants in the wastewater and then converts it into energy that it can use to grow and reproduce. Boiling is the most certain way of killing all microorganisms. According to the Wilderness Medical Society, water temperatures above 160 F (70 C) kill all pathogens within 30 minutes and above 185 F (85 C) within a few minutes. Dry heat kills microorganisms through a process of protein oxidation rather than protein Coagulation. Examples of dry heat include. Microbiological ovens employ very high dry temperatures: 171°C for 1 hour; 160°C for 2 hours or longer; or 121°C for 16 hours or longer depending on the volume.

Do not forget UV and other ionizing radiation.
