HCU, Nasa researchers discover new bacteria that could make space farming reality

Hyderabad: Astronauts at the International Space Station (ISS) may soon be able to grow their own food. The collaborative discovery of novel bacterial strains aboard the ISS by researchers from NASA's Jet Propulsion Laboratory (JPL) and the University of Hyderabad (UoH) suggests that it could be possible.

A recent discovery of new bacterial strains from different locations aboard the International Space Station flights may help in creating the 'fuel' to help plants withstand such stressful situations.

The bacterial strains belonging to the family Methylobacteriaceae, were isolated from different locations aboard the ISS across two consecutive flights. While one strain was identified as Methylorubrum rhodesianum, the other three were previously undiscovered and belonged to a novel species.

Genetic analyses revealed them to be closely related to Methylobacterium indicum. The researchers named the novel species as Methylobacterium ajmalii, in honour of the renowned Indian biodiversity scientist Dr. Ajmal Khan (former professor at Annamalai University). The genome analysis of Methylobacterium ajmalii strains revealed the presence of genes that are involved in promoting plant growth.

Commenting on the discovery and based on the genomic data, the lead authors said the strains might possess "biotechnologically useful genetic determinants that may help growing plants in extreme places where resources are minimal". However, further experimental validations are being done to prove that it could, indeed, be a potential game-changer for space farming.

The research findings are a collaborative effort of three organizations from the USA. The research teams were led by Dr. Kasthuri Venkateswaran (NASA's Jet Propulsion Laboratory) and C.C Wang (WorldQuant Initiative for Quantitative Prediction), and Prof. Appa Rao Podile from the University of Hyderabad with expertise on plant growth promoting bacteria and plant microbiome and Dr. Ramprasad (CSIR-pool Scientist).
