Vampirovibrio chlorellavorus

Vampirovibrio chlorellavorus is a species of bacterium that belongs to the family Bdellovibrionaceae. It is known for its unique predatory behavior towards the green alga Chlorella vulgaris.

Description

Vampirovibrio chlorellavorus is a Gram-negative bacterium that has a helical shape and is typically around 1-2 micrometers in length. It is an obligate parasite that preys specifically on Chlorella vulgaris, a common freshwater alga.

Discovery

The discovery of Vampirovibrio chlorellavorus was first reported in a study published in 1976 by researchers studying interactions between bacteria and algae in aquatic environments.

Predatory Behavior

Vampirovibrio chlorellavorus exhibits a unique predatory behavior where it attaches to the surface of Chlorella vulgaris cells and penetrates them to consume their contents. This process ultimately leads to the lysis of the algal cells.

Significance

The study of Vampirovibrio chlorellavorus and its predatory behavior provides insights into the dynamics of microbial interactions in aquatic ecosystems. Understanding the mechanisms by which this bacterium preys on algae can have implications for the control of algal blooms and the maintenance of ecological balance in freshwater environments.
