What is the term for the process of inoculating microbes into soil ?
Bioaugmentation
Bioremediation uses living organisms, mostly microbes, to break down pollutants in soil and water. It can be carried out either by helping the microbes already present or by adding new ones.
Bioaugmentation is the deliberate inoculation of selected or specially cultured microorganisms into contaminated soil or water to increase the population able to degrade a particular pollutant. It is used when the native microbial community lacks the ability, or the numbers, to break the contaminant down quickly.
Biostimulation works the other way: it adds nutrients, oxygen or electron acceptors to stimulate the indigenous microbes without introducing new ones. Bioventing supplies air (oxygen) to the unsaturated soil zone to encourage aerobic degradation by existing microbes. Biosparging (printed as “Biosparaging”) injects air below the water table for the same purpose. Only bioaugmentation involves inoculating microbes into the soil.
Bioaugmentation option is correct.
