What is the term for the process of inoculating microbes into soil ?

  • A.Bioventing
  • B.Biostimulation
  • C.Bioaugmentation
  • D.Biosparaging

Answer: C

The process is Bioaugmentation.

In bioremediation, bioaugmentation means adding (inoculating) selected microbial strains to contaminated soil or water to speed up the breakdown of pollutants.

Biostimulation instead adds nutrients or oxygen to stimulate the microbes already present; bioventing supplies air to the unsaturated soil for the same purpose; and biosparging injects air below the water table. None of these adds microbes.
