A prominent example of a Sarcina bacterium is Sarcina ventriculi.
Understanding Sarcina Bacteria
Sarcina refers to a genus of bacteria distinguished by their unique cubic or packet-like arrangement. These spherical bacteria divide in three perpendicular planes, leading to their characteristic formation into groups of eight or more cells, often resembling a compact bale.
Sarcina ventriculi: A Key Example
Sarcina ventriculi is significant as the type species for the Sarcina genus. This bacterium is remarkably resilient and can be found in a variety of environments, making it a subject of interest in microbiology.
Characteristics and Habitats of Sarcina ventriculi
Here's a breakdown of the key aspects of Sarcina ventriculi:
| Aspect | Description |
|---|---|
| Example Name | Sarcina ventriculi |
| Type | The definitive type species representing the Sarcina genus. |
| Cellular Form | Spherical cells that commonly arrange themselves into cube-like packets, formed by cell division occurring in three perpendicular planes. |
| Primary Habitats | This bacterium thrives in diverse environments, including: - The surface of cereal seeds - Soil and mud - The stomachs of humans, rabbits, and guinea pigs, where its exceptional acid tolerance allows it to survive and grow in highly acidic conditions. |
| Notable Feature | Known for its ability to ferment carbohydrates into ethanol and carbon dioxide, even under extremely acidic conditions. |
Significance of Sarcina ventriculi
Sarcina ventriculi is particularly notable for its metabolic flexibility and its unusual tolerance to highly acidic conditions, a trait that enables it to colonize the stomachs of various mammals. Its unique characteristics make it an important subject for understanding microbial adaptation and its potential roles in both environmental processes and gut microbiology.
