Microorganisms, especially bacteria, also exist in places where humans are. The International Space Station (ISS) is no exception.
However, the ISS remains cleaner than anywhere else in the world.
Astronauts also take turns cleaning while they are on other missions. Vehicles carrying cargo and cargo to the International Space Station are also subject to sterilization before being fired, and astronauts heading to the space station are seized on a spacecraft for 10 days prior to launch.
Marc Hault microbiologist at the Johnson Space Center in the United States said that once every three months samples are taken at two places in each module connected to the space station for hygiene purposes.
The Los Cosmos Russian Space Agency, which uses the International Space Station together with the United States, is also closely monitoring all parts of the station.
To check the hygiene status, a sample is taken from the air and the floor in the station, and cultured in a laboratory dish containing mediators that serve as means of growth of bacteria and fungi. Then, send these plates to the ground to observe what microorganisms are growing.
Basically, the same method as used on the ground is used to prevent the occurrence and growth of microorganisms in the treatment and preparation of drinking water.
The International Space Station periodically inspects drinking water related systems. Drinking water quality testing was originally conducted once a month, but it has always been very clean and has changed to once every three months thereafter.
Haute said the astronauts' drinking water is cleaner than any water we drink on Earth, comparing only the amount of microbes remaining.
The International Space Station has medical requirements to monitor the station environment. The space station also has the same microorganisms found in any home or office.
Scientists claim that microbes are found everywhere in the station, but they are only part of causing medical problems, and that it is only possible if the situation is right.
Medical officers at the International Space Station closely monitor any anomalies to prevent any possible medical problems caused by microorganisms that may be present, and if the signs are found, additional disinfection of space stations do.
The presence of microorganisms does not have a significant effect on the health of astronauts. This is possible only if the bacteria that should be found in the toilet should be found only in the toilet.
In some cases, microorganisms that are considered to be at risk have been found to have a slightly different appearance from normal bacteria, without any effect on DNA results.
It is difficult to distinguish between what is a threat and what is not because microbes are not very related to each other.
In recent hygiene tests, 11 kinds of bacteria were found. The bacteria found were found to be anthrax, gram-positive bacillary, and tuberculosis strains that were discovered in 2014.
All of these bacteria are known to be microorganisms that are harmful to humans and are commonly found where humans exist on Earth.
The researchers were able to identify samples of each species, and some of the bacteria found here were very similar to anthrax as a result of DNA hybridization.
However, none of the bacteria found have potential toxins because they do not have the plasmids or physical properties that secrete them.
The sanitary inspection of the existence of any other microorganisms on the International Space Station is continuing.
Studies using different techniques have been conducted on the environment where microorganisms exist in space stations.
The studies focused on different goals than NASA's regular sanitary inspection, but there were times when NASA would help maintain NASA's space station cleanliness.
Haute said he needed to look carefully at the interpretation of the results, although there is a need to study new and different methods of monitoring microbes in space stations.
NASA will continue to monitor the sanitary conditions of the International Space Station to help astronauts perform their mission in a safe and healthy environment.
Research into the effects of long-term space travel on astronaut microbioam (the entire genetic information of microbes living in our bodies) is still under way, and short-range space travel has been linked to the human immune system and microbial Research has already been conducted in 2013 on how it affects humans.
In the study, microbial samples were extracted with a certain period in each part of the body of the astronaut, and these samples were sent to Earth for analysis with samples taken from the space station.
NASA and the Sloan Foundation have entered into agreements to support microbiomic research on the study environment, the microbiological environment within the artificial environment, and the microbiological environment within the main space station.
Five postdoctoral fellows were given the opportunity to experiment at NASA's repository of microbial samples collected from the space station module over the last decade for exchanges.
The purpose of these interchange experiments is to better understand how microbial communities form, adapt, and evolve in space stations. This experiment is very important because the microorganisms follow the path of humans.
