The researchers found microbes without respiratory structures.

The discovery beyond common sense could lead to a mystery into the early life of the Earth and a clue to the limits of life, as well as to the discovery of a near-impossible structure of ordinary life, such as breathing, in the deep waters of the Japanese marine research and development agency Kochi Core Research.
the results of the study were recently published in the British Journal of Science.
California, u.S.A., a rare spring was spotted 1.2 kilometers below a rock.
the spring water is ultra-alkaline, ultra-reductive, with little oxygen, carbon, phosphorus and other life-sustaining substances, and is considered to be a very cruel environment similar to the early Earth's about 4 billion years ago.
the team analyzed the genomes (full genetic information) of the microorganisms that live in the water and identified 27 microbes.
found that 70% of the basic structures of life, such as breathing and so-called synthetic "ATP" energy metabolism, do not have unknown microorganisms, the genome only replication and cell membrane synthesis functions, can be described as the smallest chromosome in traditional life.
microbes attached to the rock, it can be seen that energy is obtained from the minerals of the rock, but its structure is not yet known.
known to be a super-reduced environment with little oxygen in the early days of the Earth, this microbe may have been primitive life in the early days of Earth.
researchers believe that the presence of common-sense microbes in very harsh environments is surprising and may be a clue to the study of life beyond Earth.
