What is Salinibacter ruber?
Salinibacter ruber is a kind of red alga.
Red algae are plants that obtain energy by photosynthesis. They live in salt water, but can tolerate a wide range of salinities. Algae are a diverse group of organisms that are found almost everywhere. Red algae include the largest group of marine phytoplankton.
Red algae are the foundation of many ecosystems. They are an important food source for a great variety of marine animals. They are also very useful as biofuels.
The World Red Algal Database is the largest online database of red algae. It includes information on the geographic distribution, taxonomy, ecology and distribution of species, as well as their commercial value. The most common type of red algae are rhodophytes, such as Gracilaria or Ceramium. These organisms have a characteristic branching structure and use the energy from light to make carbohydrates.
Glaucophytes are sometimes called cyanophytes because of the blue-green color of the cells. Their shape is more leaf-like than other red algae. They are not a true plant; rather they are a multicellular alga that uses photosynthesis to synthesize carbohydrates and lipids.
Both groups are part of a larger group called chromophytes. Red algae are one of the three classes of chromophytes. The other two are chlorophytes and charophytes. Their presence provides a source of energy for reef fish, and the corals can use them as a food source. They are an important component of the nutrient cycle of the reef, and they can affect water clarity and the flow of nutrients and carbon.
Red algae tend to grow in high-light environments, and are often found where there is little competition. When an alga grows near a coral, it usually overgrows the coral and then dies. It is thought that the alga uses the coral's skeleton as a substrate and releases nutrients to feed the coral.
Some red algae are known as turf algae because they grow in large mats that can cover entire reef areas. Like corals, they provide a habitat for other organisms.
