Suara.com – Researchers from the United States and India who worked with NASA, find four of a kind bacteria who live in different places on Space Station International (ISS). However, three of them have never been known before by science.
Three of the four strains were isolated in 2015 and 2016, where one bacteria was detected in the top panel of the research station, the second was found in Cupola, the third was found on the surface of the dining table, and the last one was found in the HEPA filter.
The four strains belong to a family of bacteria found in soil and fresh water.
Such types of bacteria are involved in nitrogen fixation, plant growth, and can help stop plant pathogens.

Reporting from Science Alert, Wednesday (17/3/2021), the bacteria appeared on the ISS most likely related to plants planted by astronauts for years.
One of the strains was identified as a species called Methylorubrum rhodesianum.
While the other three were sequenced and experts found all three belonged to the same species and had never been previously identified.
In the study published in Frontiers in Microbiology, the three new strains were named IF7SW-B2T, IIF1SW-B5, and IIF4SW-B5.
Remember microbes surviving the harsh conditions of the ISS environment, the team of experts put all four strains through genetic analysis to look for genes that could be used to help promote plant growth.

“This will further assist in the identification of genetic determinants that might promote plant growth under microgravity conditions and contribute to the development of independent plants for future long-term space missions,” said the team of scientists led by Swati Bijlani, a geneticist at the University. of Southern California.
