Pedomicrobium manganicum
Description and Significance
Pedomicrobium manganicum are hyphal budding bacterium. The structure of the bacterium is spherical with up to five hyphae per cell [2]. As a terrestrial extremophile, it inhabits particularly harsh environments such as desert rock surfaces in which it can be susceptible to massive variation in temperature as well as UV radiation. Desert rock surfaces are not the only environment it is found in. It can also be found in soils, water systems, and various aquatic systems as biofilms [5]. Pedomicrobium manganicum can be used for may bioremediation processes such as removing manganese from water purfication systems to the removal of uranium and radium from Uranium Mill Tailing Remedial Action Sites [5].
This image represents the spherical shape with hyphal budding regions of the Pedomicrobium manganicum under transmission electron microscopy [1].
Genome Structure
The genome of Pedomicrobium manganicum has a size of approximately 5Mb and has a G/C content of 66%. [5] The number of chromosomes and weather they are circular or linear is unknown [5]. The manganese oxidation operon and has a Genbank Accession number of AM049177. [5]
Cell Structure, Metabolism and Life Cycle
Interesting features of cell structure; how it gains energy; what important molecules it produces.
Ecology and Pathogenesis
Habitat: Pedomicrobium manganicum is an extremophile that lives on desert rocks and is also able to forms biofilms in aquatic environments. [1][5]
Biogeochemical Significance: Pedomicrobium manganicum is known to oxidize Manganese[5]. This species is also known to create Iron Oxide[5] and Gold deposits[1][5].
Contributions to Environment: Aquatic sources of oxidized Manganese produced by Pedomicrobium manganicum can provide an essential source of usable Manganese for many animal species. Animals that have a lack of Manganese in their diet may experience reduced growth and reproductive function, impaired glucose and lipid metabolism and skeletal abnormalities. [6][7] Ingestion of excess Manganese may lead to Manganese toxicity which has neurological symptoms similar to the effects of Parkinson's disease.[8] These symptoms only occur in high concentrations, about 14 mg/liter.[9]
