Guest Lecture by BARC Scientist Dr. Hari S. Misra at CUSB
“World’s most radiation-resistant Deinococcus bacteria holds promise of radiation pollution says BARC scientist Dr. Misra, at CUSB”
The research being carried out in the laboratory of Prof. Hari S. Misra in the country’s premier research institution, Bhabha Atomic Research Centre at Mumbai has opened up a whole range of possibility from radiation contamination and bioremediation to development of anti-oxidants. In a seminar organised by the Department of Bioinformatics, Central University of South Bihar, Gaya, Dr. Misra shared exciting research findings and thrilled the audience in the hall packed with students, research scholars and faculty members on 16th September, 2019.
Deinococcus radiodurans is one of the most radiation-resistant organisms known to mankind, which can survive even up to 1,500 kilorads dosage of radiation, a level hundreds of times higher than most other organisms and it can survive cold, dehydration, vacuum, and acid. However, the underlying mechanism of its extraordinary ability has eluded scientist for years. Dr. Misra said that the discovery of a RqkA protein and its role in the process has elucidated an unconventional mechanism of how an organism can survive such a lethal dose of radiation and recoup from the damages incurred in its genomic DNA during irradiation. Until yet, SOS response has been identified primary mechanism, adopted in nature to tackle the DNA damages upon exposure to radiation. In his research career spanning 25 years, Dr. Misra shared many key findings and touched upon a whole range of topics. Dr. Misra is currently heading the molecular biology division of Bhabha Atomic Research Centre at Mumbai.
Dr Misra said that hundreds of students visit BARC each year to carry out summer training and short-term projects. But students coming from Bioinformatics Department and CUSB has impressed him most because of dedication and enthusiasm with which they work. Dr. Misra further appreciated the training and research going on in the department. Earlier Bioinformatics faculties Dr. Rathore, Asheeh, Ajay, Krishna, Vijay, Durgvijay, and Anil greeted him and apprised him of various activities and programs going on in the Department of Bioinformatics. The seminar was attended by several Professors of life science, biotechnology and environmental science, including Prof. Ram Kumar, Dean of the School of EBES and Prof. Rizwan-ul Haque, Head, Department of Biotechnology.
