Interesting Bacteria that can switch to all four major types of Metabolism for survival: Rhodopseudomonas palustris

Most of the living organism that live on earth gets energy by metabolism a process in which  within cell of living organism some chemical transformation occurs that allow living being to grow with their environments. Plant use sunlight to survive, Human and animal use oxygen and some of organism that grow in absence of light use other source of energy to survive example Pompeii worm lives near hydrothermal vent under sea.

But none of these are similar to Rhodopseudomonas palustris an amazing bacterium that can survive in any condition and grow with or without help of oxygen or sunlight and can use organic or inorganic compound for energy. It has exceptional metabolic adaptability and grows by any one of the four modes of metabolism that support life on earth like photoautotrophic or photosynthetic where energy from light and carbon from carbon dioxide used to get energy, photoheterotrophic where energy from light and carbon from organic compounds to originate energy, chemoheterotrophic where carbon and energy from organic compounds required to generate energy and chemoautotrophic where energy from inorganic compounds and carbon from carbon dioxide used to get energy.

This bacterium is capable of changing atmospheric nitrogen into ammonia and inorganic carbon to organic compounds. This bacterium can change sunlight into energy and atmospheric carbon dioxide into biomass. It also capable of degrading main constituent of wood also known as lignin the second most plentiful polymer present on the earth.

Scientists are not able to understand how this bacterium modifies its metabolism in response to environmental changes. It mostly found in many types of marine environments and soils for example remote swine waste lagoons, marine coastal, earthworm droppings, sediments and water reservoir.

This exception quality of Rhodopseudomonas palustris make it suitable candidate for several commercial applications like biodegradation in hydrogen production or even in electricity generation. As per research this bacterium can use natural conductivity to pull electrons from minerals found deep in soil and sediment while remaining at the surface, where they consume the sunlight needed to produce energy.

This purple non-sulfur phototrophic bacterium is not the energy production for distribution and use, but it is to avoid energy expenditure on waste treatment as well.
