To deprive of the power of reproducing; to render incapable of germination or fecundation; to make sterile.
To destroy all spores or germs in (an organic fluid or mixture) or on (a medical instrument), as by heat, so as to prevent contamination by bacteria or other organisms. A common method of sterilization in laboratories and medical facilities is to heat a liquid sample or an instrument in an autoclave.
To destroy all spores or germs on (a surface) by wetting with an antiseptic liquid, such as an alcoholic solution.
(1) It is often recommended that the soil medium in which seeds are germinated should first be sterilized; to do this, soil can baked in the oven. To kill the damping-off fungi, the soil must reach 130 degrees F for 30 minutes. Most viruses will be dead after 30 minutes at 160F. It is not, however, necessary to sterilize soil unless previous problems have occurred because, in addition to killing disease organisms, it also destroys beneficials, which contribute to soil health. (2) Before pruning plants, especially those that may harbor disease, be sure to sterilize tools with a diluted ammonia solution (see pruning entry for more information). (3) The term may also be used to describe self-sterile plants (see cross-pollination).

make sterile (super-clean) by removing dirt, germs and bacteria. A good sterilizer for hydroponic equipment is a 10 percent bleach to water solution.
To destroy microorganisms by boiling, dry heating, or steaming.
The process of treating a non-living object with a substance that will completely destroy all bacteria and other microorganisms. This is not the same as disinfecting (see above). For more information, visit the Cleaning and Cleanliness page.
