Pollution eating and Electricity Breathing Bacteria Found

Bacteria the tiny creatures that can “eat” pollution and generate electricity in the process have been captured for the first time. Washington State University scientists trekked into the depths of Yellowstone National Park in USA to extract these bacteria, which are adapted to living in geysers and hot springs that can reach over 90°C.

The “electrogenic” microbes were targeted due to their ability to produce power, which experts hope could be harnessed to power devices.

Some of these bacteria have the power to convert toxic pollutants into less harmful substances.

As they do so, the electrons passing through their body as they digest their food are dumped outside their bodies on minerals or metals, using hairlike structures that protrude from their bodies like wires.

This produces a stream of electricity in an efficient process that can be used in lowpower applications.


The bacteria are unicellular microorganisms which were first observed and reported by Anton Von Leeuwenhoeck in 1676. All bacteria are unicellular and prokaryotic. Their size and shape varies as per the species. Majority of Bacteria are in the size range of 0.5 to 50 µ, the smallest bacterium is “pasteurella” which is 0.7µ and largest bacteria Beggiota is 15-22 µ in size.

In-situ Conservation:

In-situ conservation is on site conservation or the conservation of genetic resources in natural populations of plant or animal species, such as forest genetic resources in natural populations of tree species.

It is the process of protecting an endangered plant or animal species in its natural habitat, either by protecting or cleaning up the habitat itself, or by defending the species from predators.

It is applied to conservation of agricultural biodiversity in agro forestry by farmers, especially those using unconventional farming practices. In-situ conservation is being done by declaring area as protected area.
