Description and significance
Ralstonia eutropha JMP 134 can be found in both soil and water. This bacterium has great potential for use in bioremediation as it is able to degrade an great number of chlorinated aromatic (chloroaromatic) compounds and chemically related pollutants. Ralstonia eutropha H16 was formerly known as Alcaligenes eutrophus which was originally isolated from sludge. Ralstonia eutropha JMP 134 and other strains belonging to this species are models for studying microbial production of “polyhydroxyalkanoates, and chemolithoautotrophic metabolism in aerobic heterotrophs.(JGI)” Ralstonia eutropha strains can utilize hydrogen, carbon dioxide and organic compounds for development and is model organism for hydrogen oxidation because it can nurture on hydrogen as the sole energy source. Ralstonia eutropha JMP 134 was isolated dues to its ability to degrade the herbicide 2,4-dichlorophenoxyacetic acid, which was encoded on plasmid as having the function of degrading.
Genome structure
Thermoplasma volcanium has a circular DNA with 1,584,804 nucleotides. It does not contain any plasmids. However, it possesses about 70 proteins not found in any other archaea’s genome.
Cell structure and metabolism
This microbe has a unique cell membrane that contains tetraether lipids. It lacks any kind of cell wall, which causes it to have irregular shapes and is capable of assuming different shapes. The microbe uses multiple flagella for high motility. Thermoplasma volcanium is heterotrophic and therefore requires it to obtain nutrients from other organisms especially those who cannot survive in acidic or high temperature environments. Depending on its living conditions, the microbe is both anaerobic and aerobic. It is anaerobic in the presence of elemental sulfur.
Ecology
Due to its evolutionary ties to eukaryotes, Thermoplasma genus can be used as model organism for researches.
Pathology
There is no known pathogen among different strains of Ralstonia eutropha.
Application to Biotechnology
Does this organism produce any useful compounds or enzymes? What are they and how are they used?
