A current examine says that 4 strains of micro organism have been found on the Worldwide House Station (ISS). Three of the bacterial strains are new and have been beforehand unknown to science. The ISS is an orbital laboratory located in low-Earth orbit (LEO) that has seen quite a few astronauts go to to keep the station and carry out scientific experiments in its microgravity surroundings. During the last six years, astronauts on totally different crews collected samples from eight spots on the house station, to scan for the presence of microbes. Based on a CNN report, the newest bacterial strains are from the Methylobacteriaceae household.

All of the 4 strains found belong to a household of micro organism present in soil and freshwater, however scientists have been solely aware of Methylorubrum rhodesianum. By way of their findings, researchers have found that the opposite three microbes are family of Methylobacterium indicum – a bacterium remoted from rice that can use primary one-carbon compounds like methanol or methane as their carbon supply to develop. The micro organism are concerned in nitrogen fixation, the place molecular nitrogen (N2) within the air is transformed into ammonia (NH4) and plant progress, and will maintain away plant pathogens. Scientists suppose the micro organism shall be useful to the expansion of vegetation in house – a useful instrument for future astronauts that reside in house for lengthy intervals of time.

Stating that the brand new strains may need ‘biotechnologically-useful genetic determinants,’ scientists mentioned that isolation of novel microbes that help in plant progress throughout antagonistic situations is important. NASA researchers Kasthuri Venkateswaran and Nitin Kumar Singh labored on this analysis, in response to the assertion. Each are stationed on the Jet Propulsion Laboratory (JPL) in Pasadena, California, the place Kasthuri is a senior analysis scientist and Nitin is planetary safety engineer.

In honour of the Indian scientist Ajmal Khan, the researchers have voted to call the brand new strains of micro organism Methylobacterium ajmalii, in response to a Voice of America report. Together with Venkateswaran and Singh, researchers from College of Southern California, Cornell College and College of Hyderabad have been additionally concerned with the examine.

It was revealed within the peer-reviewed scientific journal Frontiers in Microbiology on 15 March.
