Three new species of bacteria, which are not found on Earth and which are highly resistant to ultra-violet radiation, have been discovered in the upper stratosphere by Indian scientists. One of the new species has been named as Janibacter hoylei, after the Distinguished Astrophysicist Fred Hoyle, the second as Bacillus isronensis recognising the contribution of ISRO in the balloon experiments which led to its discovery and the third as Bacillus aryabhata after India’s celebrated ancient astronomer Aryabhata and also the first satellite of ISRO.
The experiment was conducted using a 26.7 million cubic feet balloon carrying a 459 kg scientific payload soaked in 38 kg of liquid Neon, which was flown from the National Balloon Facility in Hyderabad, operated by the Tata Institute of Fundamental Research (TIFR). The payload consisted of a cryosampler containing sixteen evacuated and sterilised stainless steel probes. Throughout the flight, the probes remained immersed in liquid Neon to create a cryopump effect. These cylinders, after collecting air samples from different heights ranging from 20 km to 41 km, were parachuted down and safely retrieved. These samples were analysed by scientists at the Center for Cellular and Molecular Biology, Hyderabad as well as the National Center for Cell Science (NCCS), Pune for independent examination, ensuring that both laboratories followed similar protocols to achieve homogeneity of procedure and interpretation.
