Species

Thiomargarita Magnifica

Description and Significance

Thiomargarita magnifica is characterized of large Thiromargarita cells. It is found in tropical marine coastal environments and is found to be 1cm in length. Thiomargarita magnifica is important for antibiotic production, evolution, the tree of life, and the sulfur cycle.

Genome Structure

DNA in Thiomargarita magnifica is concentrated in membrane bound compartments. These membrane bound organelles which contain the DNA are called “pepin.” Thiomargarita magnifica has a genome as large as baker’s yeast, as it contains three times the median gene count for prokaryotes. Additionally, it contains a large set of genes for sulfur oxidation and carbon fixation.
