The bacteria can eat detergent to survive.

June 8 (UPI) -- Few places for microbes are as impenetrable as the dust-free chambers of NASA's assembled spacecraft, the Atlantic Monthly reported.
microbes floating in the air must be tested by multiple filters; the microbes on employees are also blocked by masks and full-body hooded workclothes.
even if some microbes have the ability to survive in space or other planets, they will not escape NASA's "magic claws" on Earth.
cleanrooms, floors and various equipment are constantly scrubbed with alcohol-based solvents, and most microorganisms are removed.
all these measures are designed to "protect the planet", that is, to prevent Earth microbes from polluting other alien worlds aboard our spacecraft.
this principle is enshrined in current international treaties, and NASA is making every effort to uphold it.
, after all, microbes smuggled from the Earth may be classified as extraterrestrial.
but it's impossible to completely eliminate microbes, and even NASA's cleanroom has a highly resistant microbiome that somehow survives a rigorous sterilization process.
these microorganisms are dominated by alistofa, and they are usually found in soil and water.
when other microorganisms disappear during cleaning, the bacteria remain.
scientists have isolated the strain from the surface of the Mars orbiter, from the ground where the Mars lander was assembled, from the outside of the International Space Station, and even from the station's drinking water.
Now, a team of scientists led by Professor Rakesh Mogul of California State Polytechnic University has discovered a survival technique for the bacteria: These microbes can eat cleaning products designed to wipe them out to survive. "You can clean the rooms and disinfect them, but the microbes are still there, " says
Mogur.
it's a bit of a "Jurassic Park" - life always wants to survive.
" Mogher's team, which was made up of undergraduates, used strains of campanco that were recovered from the dust-free chambers and raised them at very low nutritional levels.
in this extreme condition of strict lying restrictions on diet, bacteria can ethanol as the main growth factor.
they use the carbon inside to make their own DNA, proteins and other basic molecules by burning ethanol.
team found that no-actuloba may also grow in isopropanol, the main chemical used to clean the surface of the room, and Kleenol 30, a cleaner used to scrub the floor of the room.
even if they can't use these substances as energy, they can break them down.
can even withstand the treatment of hydrogen peroxide (hydrogen peroxide), a chemical used in bleaches, detergents and disinfectants. "The persistence of microbes in the dust-free chambers used to assemble spacecraft has been widely considered a troubling problem over the past 20 years," said Lisa Pratt, nasa's Planetary Conservation program officer at
.
" and new research shows that disinfectants designed to kill bacteria are feeding certain microorganisms and even increasing their tolerance.
"the harsh, dry and constantly bombarded environment of the clean scouring chambers, only the most resilient bacteria can survive, and the strains of the bacteria are extremely tough."
they can withstand hydrogen peroxide, drying, radiation, high pressure and high temperatures of up to 80 degrees Celsius.
some strains are resistant to antibiotics, causing pneumonia outbreaks in hospitals.
but Mogul noted that none of the strains he studied were known to cause disease.
Despite this, The study by Mogul and others means that NASA may have to accelerate the pace of its "planetary protection" program, especially in future missions to detect life on other planets.
they may try to take turns using different types of solvents to avoid spawning drug-resistant flora.
but Mogul says the choice of chemicals they can use becomes a bottleneck because they need to kill the microbes without harming spacecraft. the persistence of
aureus should cause awe, not panic.
newspapers often publish sensational reports about bacteria lurking in everyday items, from wallets to keyboards, from doorknobs to cell phones.
but the fact that "bacteria are everywhere" is inescapable. "There is no 100 percent barren land in the world, " says
Mogur. "
