Experiments using prokaryotes have led to important advances in DNA technology.

Prokaryotes are the principal agents in bioremediation, the use of organisms to remove pollutants from the environment.

Some other uses of prokaryotes:

Recovery of metals from ores

Synthesis of vitamins

Production of antibiotics, hormones, and other products.
