Bacterivore

Bacterivores are free-living, generally heterotrophic organisms, exclusively microscopic, which obtain energy and nutrients primarily or entirely from the consumption of bacteria. Many species of amoeba are bacterivores, as well as other types of protozoans. Commonly, all species of bacteria will be prey, but spores of some species, such as Clostridium perfringens, will never be prey, because of their cellular attributes.

In Microbiology

Bacterivores can sometimes be a problem in microbiology studies. For instance, when scientists seek to assess microorganisms in samples from the environment (such as freshwater), the samples will often be contaminated with bacterivores, which will interfere with the growing of bacteria for study.

Adding cycloheximide can inhibit the growth of bacterivores without affecting some bacterial species^[1] but it was shown to inhibit the growth of some anaerobe prokaryotes.^[2]

Examples

Caenorhabditis elegans
Ceriodaphnia quadrangula
Diaphanosoma brachyura
Vorticella
Paramecium
Many species of Protozoa
