Paracoccus pantotrophus

Description and Significance

Sulfur-oxidizing strains of Paracoccus are often found in deep-sea marine sediments, while other strains can be found abundantly in waste water reservoirsl. Their ability to breakdown nitrogen makes the of particular interest to researchers for their potential as water treatment microbes.

Genome Structure

The genome includes two circular chromosomes, which encompass 13,000+ genes with a total length of about 4.2 billion nucleotides.

Cell Structure, Metabolism and Life Cycle

These gram-negative bacteria may be aerobes or facultative anaerobes. They are sulfur-oxidizing chemoautotrophs, and are also well known for their ability to degrade Nitrogen.

Ecology and Pathogenesis

While not pathenogenic, these microbes are still important for humans. Their denitrifying ability is currently being researched for its potential to be utilized for water treatment purposes, such as helping to make wastewater cleaner for reuse.
