Table of Content

Dr. Rajan Kumar Gupta (b. 25-10-1963) has worked on Ecophysiology of Antarctic Cyanobacteria for his Ph.D. degree with Late Prof. A.K. Kashyap of Centre of Advanced Study in Botany Banaras Hindu University Varanasi. For the past twenty years he has been working on various aspects of Antarctic microflora. Dr. Gupta was deputed by Govt. of India for his participation as Biological Scientist in Antarctica twice. He has participated in XI and XIV Indian Scientific Expeditions to Antarctica during 1991-92 and 1994-95. He has visited several countries like USA Europe Belgium Mauritius Japan Nepal Thailand South Africa Singapore and Srilanka etc. for presentation of his work on different aspects of algae. Dr. Gupta has worked on various aspects of cyanobacteria i.e. morphology ecology and nitrogen fixation biotechnological applications and published more than 100 technicalpapers in various national and overseas journals and 7 reference (research) books entitled Glimpses of Cyanobacteria Advances in Applied Phycology Soil Microflora Microbial Biotechnology and Ecology Vol-1 Vol-2 Diversity: An Overview Diversity of Lower Plants and Biotechnology: An Overview. Nine students have been awarded the D.Phil degree and Six are working under his supervision for their D.Phil degree of Various Universities of Uttarakhand. Dr. Gupta is a recipient of Research Award from University Grants Commission New Delhi. Dr. Gupta is member of number of organizations in India and abroad. He is the Fellow of the Society for Environment and Ecoplanning and International Botanical Society and chaired various sessions in the conferences in India and abroad. He is in the editorial and advisory board of various journals. Presently Dr. Gupta is teaching Microbiology and Biotechnology in Department of Botany Dr. P.D.B.H. Govt. P.G. College Kotdwar (Pauri) Uttarakhand. Dr. Satya Shila Singh (b. 28.10.1967) B.Sc. (Gorakhpur University) M.Sc. (Purvanchal University) and Ph.D. (Botany Banaras Hindu University). She did her Ph.D. on the research problem related to the Physiological and Biochemical Studies of Azolla- Anabaena under salt stress. Presently Dr. Singh is serving as an Assistant Professor in the Department of Botany Guru Ghasidas Vishwavidyalaya (Central University) Bilaspur Chhattisgarh. She has 3 years of teaching and 16 years of research experience with specialization in Stress Physiology and Molecular Genetics of Cyanobacteria. She has published number of papers in the journals of International and National reputes. She is recipients of Junior & Senior Research Fellowship (University of Grants Commision) Research Associateship (Council of Scientific and Industrial Research New Delhi) and DST Young Scientist award. Her research activities mainly focuses on systematics of diazotrophic microorganisms viz. cyanobacterial strains collected from different parts of India and Frankia strains isolated from root nodules of Hippophae salicifolia D. Don located at high altitude of Eastern Himalayas North Sikkim India and both of them comprise the largest global suppliers of biologically fixed nitrogen in the environment through the enzyme nitrogenase complex encoded by three structural genes i.e. nif-HDK which has been highly conserved throughout the evolution. She has also detected molecular diversity and phylogenetic relationships among the Frankia strains and heterocystous cyanobacteria based on amplification and sequence analyses of highly conserved 16S rRNA molecule nitrogen fixing genes (nifH and nifD) short tandem repetitive repeats and highly iterated palindromic sequences. Siderophore production and their interaction with specific metal ions are also one of the prime targets of his research programme. She has also investigated on various factors regulating acid/alkaline phosphatase activity in cyanobacteria and Azolla-Anabaena system and also their potential application as a suitable biofertilizer. Interest in salt tolerance of Anabaena azollae (Trichormus azollae) forming symbiotic association with Azolla and Frankia strains with Seabuckthorn (Hippphae salicifolia D. Don) arises for its possible contribution in nitrogen economy especially under saline environment. Recently her laboratory also focusing on the molecular approaches to study the community diversity of paddy fields especially on diazotrophic cyanobacteria of Chhattisgarh.
