Planctomycetota

Planctomycetota is a phylum of bacteria that was first described in 1999. It is characterized by its unique cell structure, which includes a cell membrane and a cell wall that is composed of a peptidoglycan layer and an outer membrane. The outer membrane is unique to Planctomycetota and is composed of a lipid bilayer with embedded proteins. This outer membrane is thought to play a role in the bacterium's ability to survive in extreme environments.

Planctomycetota are found in a variety of environments, including soil, water, and even the human gut. They are known for their ability to degrade complex organic compounds, such as hydrocarbons and xenobiotics, making them useful in bioremediation efforts. Some species of Planctomycetota are also known to produce antibiotics and other secondary metabolites.

The phylum Planctomycetota is divided into two classes: Planctomycetia and Gemmatimonadia. Planctomycetia is further divided into two orders: Planctomycetales and Acidothermales. Gemmatimonadia is divided into two orders: Gemmatimonadales and Gemmatimonadales incertae sedis.

Planctomycetota are of interest to scientists due to their unique cell structure and their potential applications in bioremediation and biotechnology. However, more research is needed to fully understand the biology and ecology of these bacteria.
