Mystery microbes of the sea What gobbles up millions of tons of poisonous ammonia each year, making the water safe for fish?
January 2, The astronauts found the mystery microbes were two commonly associated with Mystery microbe human microbiome. Previously, microbes had to be sent to Earth for analysis, and this new sequencing marks an important step in diagnosing astronaut illnesses and, someday, identifying any DNA-based life found on other planets, NASA officials said in a statement.
Researchers back on Earth have now verified the microbe identifications are correct, marking the experiment a success. As a part of the Genes in Space-3 mission, astronauts on the space station last year touched a petri plate to surfaces on the space station and grew the bacteria found there into colonies, which NASA astronaut Peggy Whitson used to amplify and then sequence their DNA.
In JulyNASA astronaut Kate Rubins became the first to sequence DNA in spacebut this latest experiment was both the first time cells were transferred for analysis and the first time unknown organisms were identified in space. Rubins used mouse DNA sent from Earth. It was the first time the process had been performed in space.
Scientists sequenced the microbes again on Earth and verified that each had been identified correctly. Neither of the two species are considered pathogens. But at last, they had successfully combined the two, NASA officials said.

Scientists have discovered that microbes in Antarctica have a previously unknown ability to scavenge hydrogen, carbon monoxide and carbon dioxide from the air to stay alive in the extreme conditions. INSIDE each one of us lies a mystery. An analysis of genes from the human gut has found DNA so unusual it could belong to microbes unlike anything that science has encountered before. Microbe Mystery Solved: What Happened to the Deepwater Horizon Oil Plume Berkeley Lab researchers simulate spill, discover new bacterium, map microbe activity Many of the bacteria that were identified were similar to oil-degrading bacteria found on the ocean surface but had considerably streamlined sets of genes for oil degradation.

“Simple life,” Phillips says. Detecting it, however, is stunningly complex. The robotic probe Europa Clipper will launch in the ’s; NASA has scheduled up to 45 flybys.
NASA astronauts successfully sequenced the DNA of microbes found aboard the International Space Station, marking the first time unknown organisms were sequenced and identified entirely in space. Identify one of four 'unknown' common bacteria using staining techniques and chemical tests.

Microbes can be classified based on a wide range of characteristics that allow them to survive and flourish in varying environments.
A major classification is based on oxygen requirement; with oxygen dependent microbes being aerobic while anoxygenic microbes being anaerobic. While it seems the mystery of the spring-smelling incubator has been solved, these microbes and molecules do not fully explain why I was inspired to write this article.
Even more intriguing, are the olfaction studies showing that the human nose is exceptionally sensitive to this compound.
Despite the mystery surrounding it, this microbe might be one of the most common life-forms on Earth. Yet for many years, biologists could not study it.
The reason: They simply could not get it .
