National Symposium on “Algal Bio-diversity and its role in Bio-remediation”Session I was chaired by Prof M Umamaheswara Rao and Dr V Sivasubramanian was the rapporteur. A special lecture on utilization of marine cyanobacteria to address pollution problems was deliverd by Dr L Uma, Head of the Department of Microbiology, NFMC, Bharathidasan University, Tiruchirappalli. She presented a detailed account on the collection of cyanobacteria from coastal areas from 1987 and establishment of a culture collection. She elaborated on the application of BGA in bio-remediation, bio-fertilizers, hydrogen production, production of antibiotics etc. This was followed by the paper session I.Maya Subramoni presented a paper on study of algal diversity of river of south Kerala in relation to certain water quality parameters. Narendra Mohan presented a paper on diversity of blue-green algae in Allen Forest Lake, Zoological Park, Kanpur, mixing with campus sewage.

He concluded his talk by introducing a technology for application of BGA for rejuvenation of sodic and saline soils. The paper session started with a presentation by R Ranjithkumar on micro algal biodiversity in various industrial effluents. Nomita Sen presented a paper on the use of photosynthetic micro algae in phycoremediation. She talked about green house gases and how micro algae like Chlorella and Dunaniella could be effectively employed to mitigate green house gases. J Kamaleswari presented a paper on Screening of freshwater algae for phycoremediation potentialities of industrial effluents and wastewaters. She has analyzed 15 types of effluents and wastewaters.Session IV was chaired by Dr Nomita Sen and Dr S Chandra was the rapporteur.Dr Divya Tiwari delivered a special lecture on toxic algal blooms. She gave a detailed account on the redtides and other types of toxic blooms and factors and effects. She also gave a detailed account on various types of toxins and their health effects on humans and animals. She concluded her talk with emphasis on methods to control toxic blooms through chemical, biological, nutritional and by manual harvesting. Francis MS presented a paper on the effect of five heavy metals at infinite concentrations on the growth of Synechocystis salina. He made an interesting observation on enhancement of growth by mercury, lead, copper and zinc at ppb concentrations. This was followed by a paper on genotoxic effects of algal and vegetable extracts on root tips of Allium sepa by S RevathiSession V was chaired by R. Rengasamy and Ms J Kamaleswari was the rapporteur. Dr C R K Reddy gave a special lecture on Seaweed Bio-diversity- global perspective and prospects for future research.
