Rhodococcus

Definition

Rhodococcus is a genus of Gram-positive, aerobic bacteria known for its diverse metabolic capabilities. It plays significant roles in bioremediation and biogeochemical cycles due to its ability to degrade various organic compounds.

5 Must Know Facts For Your Next Test

1. Rhodococcus species are characterized by their Gram-positive cell wall structure.
2. These bacteria are non-motile and often form rods or cocci.
3. Rhodococcus can metabolize a wide range of hydrocarbons and other organic pollutants, making them valuable in bioremediation processes.
4. They are part of the Actinobacteria phylum, which includes many soil-dwelling organisms involved in nutrient cycling.
5. Some Rhodococcus species have been studied for their potential to produce bioactive compounds with pharmaceutical applications.
