a new study, of microbial populations during space missions drinking water Explores how it affects security. As the astronauts live in the Earth view station biological material accumulating, developing and spreading. Although they are small, viral and bacterial strains can lead to negative consequences. Anyone who has experienced food poisoning knows the damage a single-celled organism can cause. Here in the new study, the researchers investigated these microbes. But with one difference; microbes in space…
NASA has started test drives for the flying taxi!
While the work on prototypes of flying cars continues, the flying taxi work, which is the service part of the work, begins with NASA.
They study microbes on the space station
scientists International Space StationA new study in which they investigated microbes on the ISS (ISS). naturePublished in . Clean water is essential for any mission. But getting water into space is a daunting task. Because NASAfor the water the station crew needs annually. Environmental Control and Life Support System developed.
Environmental Control and Life Support System, wastewater It cleans in a three-step process. Two different filtration process and a catalytic oxidation With this process, water is purified from organic compounds and microorganisms. At least it should be. But is it really so?
from Arizona State University Jiseon Yang and colleagues, isolated over time from the station’s water system bacterial populations determined. The team found that these various species space able to hinder their studied how they form small collective ecosystems. However, this biofilms still a bit of a mystery. We don’t know what they do outside of Earth’s atmosphere.
The study’s findings are alarming
The researchers collected data from the water system on the space station between 2008 and 2015. microbial isolates examined. In addition to the ability of biofilms to form, the team antibiotic resistance focused on a number of attributes, including bacteria They found that it could pose a real threat to astronauts. Especially during space travel. immune system considering it’s weak.
a specific bacterial isolate on the ISS. burkholderia, astronaut by exhibiting hemolytic activity (the ability to destroy red blood cells) your health proved to be at risk. However, although the water at the station seems safe for now, scientists have expressed their concerns. This study reveals that the current situation may change over time. More importantly, this variety of microbes It shows how they work together to create possible health effects.
