[ 13 ] : 185 An example of this is the microbial food web in the ocean, where "bacteria are exploited, and controlled, by protozoa, including heterotrophic microflagellates which are in turn ...
Bacteria are also used for the bioremediation of industrial toxic wastes. [231] In the chemical industry, bacteria are most important in the production of enantiomerically pure chemicals for use as pharmaceuticals or agrichemicals. [232] Bacteria can also be used in place of pesticides in biological pest control.
