    Microbial Fermentation Technology Channel: Underwater volcanic eruptions will completely change the underwater landscape for milesRecently, researchers found that an underwater volcano in the Canary Islands, 130 meters below sea level, was covered with a new, hairy white bacteriaEven more bizarre: as soon as the temperature of the volcano falls, it seems to be breeding hereAs soon as the rock temperature drops below 100 degrees Celsius, the microbes appear, says David Kirchman of the University of Delaware2011, a series of volcanic eruptions occurred in the Canary IslandsUnderwater Tagoro volcano completely covered the ocean floor with new rocks for 138 daysIn 2014, researchers from Italy and Spain travelled to the region to conduct researchThey thought the underwater area was still barren, only to find that the volcano was covered with hair-like white microbes, a microbe unprecedented for researchersthe surreal landscape is breathtaking, like finding life on MarsThe researchers named the white-haired microbe "Venus's hair." It is 3 cm long and about 36-90 microns in diameter (human hair is between 17-180 microns in diameter)Venus's hair is numerous, covering an area of about 2,000 square metersHowever, the researchers do not know where it came fromThe microbe seems to have emerged out of thin air after a volcanic eruptionIn fact, there are countless microorganisms in the sea, all waiting for the chance to settle downYou know, each drop of seawater contains millions of bacteria; in theory, only one of them is needed to open up a new habitatVenus's hair may be in this "rare biosphere" when it stumbles across a virgin habitat created by volcanic eruptions"Venus's hair" feeds on the large amount of hydrogen sulfide produced by rocksSo far, scientists have been 82 percent genetically sequencedThey found that the microbe contained a gene that secretes a protein "pump" to remove heavy metals filtered out of the new volcanic rockBy the time the researchers surveyed the area, Venus's hair had become a guest hostWorms and crustaceans began to make their home, to live in the barren landVolcanic eruptions are catastrophic, both underwater and on landIt spews molten magma and toxic gases, destroying lives and destroying habitats in all directionsBut after the destruction, new land and new life came back
