Huge bacterial carpet in the ocean

International scientists investigating life in the oceans have discovered a giant bacterial carpet in the 130,000-square-kilometer ocean off the coast of Chile and Peru.

Smaller microbial carpets were discovered off the coast of Western Namibia, southern Africa and are now able to expand their habitats throughout the world's oceans.

Experts in the Life Survey Program in the Ocean, the largest international scientific collaboration program with more than 2,000 scientists from 80 countries, said the giant bacteria were discovered from the decade. 60 of the last century, but at that time few scientists believed that bacteria could be 2-7cm long, big enough to see with the naked eye.

These bacteria multiply very strongly due to hydrogen sulphide toxic gas in waters at depths of 50-100 meters below sea level, where there is little or no oxygen.

This giant bacterium may have been the master of oceans during the Pristine period from 2.5 billion years to 600 million years ago, when the oceans did not have dissolved oxygen. The bacterial fossils of this period are very similar to the newly discovered bacteria.

Scientists have confirmed that the acidic environment is rising in the oceans due to the effects of climate change that can affect microbial systems.

50 years ago, in 1 liter of seawater contained about 100,000 bacterial cells but now in 1 liter of seawater or 1 gram of mud in the seabed contains more than 1 billion microorganisms.

Scientists from the research program also confirm the geographical link between the giant bacteria and the catch of seafood. They can play an important role in creating extremely rich and rich fisheries.

About 50% of the world's fish production is caught in fishing grounds off the west coast of South America, where the giant microbial carpet is.
