Researchers have properly revived microbes that experienced lain dormant at the base of the sea considering that the age of the dinosaurs, making it possible for the organisms to eat and even multiply just after eons in the deep.
Morono explained that oxygen traces in the sediment allowed the microbes to stay alive for millions of years while expending virtually no energy.
The microbes grew, multiplied and displayed diverse metabolic activities.
Professor and research study co-author Steven D'Hondt, from the University of Rhode Island, stated the microbes came from the earliest samples taken from the seabed. "The most exciting part of this study", D'Hondt says, "is that it basically shows that there's no limit to life in the old sediment of Earth's ocean".
As reported by Gizmodo, an global team of scientists led by geomicrobiologist Yuki Morono from the Japan Agency for Marine-Earth Science and Technology revived these microbes that are actually from 101.5 million years ago.
In new research, ancient sediment samples have been gathered by Japanese marine scientists ten years ago during an expedition to the South Pacific Gyre, a "desert" in terms of marine biology. As a result, very little organic matter falls to the seafloor more than three miles below.
Dr Morono incubated the microbes for up to 557 days in a secure laboratory setting, providing carbon and nitrogen food sources such as ammonia, acetate and amino acids.
The researcher added that when they were first buried, the sediments would have contained one million cells per cubic centimetre. "But what we found was that life extends into the depths of the ocean from the sea floor to the underlying rocky basement".
Genetic analysis revealed most of these microbes to be aerobic bacteria, which require oxygen to live.
They bought their solution: microbes that had been trapped in seabed sediments deposited 100 million several years in the past could be revived with the ideal food and a bit of included oxygen.
The relatively slow accumulation of sediments in the South Pacific Gyre ended up being key to the cells' survival, The Guardian reports. The authors report that if sediment accumulates at a rate of no more than three to six feet every 1 million years, it can remain oxygenated enough to support bacteria.
Researchers also explained that if the Red Planet is once home to living organisms, there's a chance that life on Mars could also be in a dormant, revivable state.
