Lipid content and fatty acid composition in N2-fixing cyanobacterium Anabaena doliolum as affected by molybdenum deficiency
(Kluwer Academic Publishers, 1993) D.S. Rathore; A. Kumar; H.D. Kumar
Anabaena doliolum grown under molybdenum deficiency produced less biomass (on a dry wt basis) and the cells had lower protein content but higher carbohydrate content than Mo-grown material. Molybdenum deficiency led to a slight decrease in chlorophyll a, a 1.5-fold increase in carotenoids and a 1.4-fold increase in total lipid but there was no difference in the lipid profiles of Mo-enriched and Mo-deficient cells. Molybdenum deficiency caused increases in the cell contents of digalactosyl diacylglycerol and phosphatidylglycerol and decreases in monogalactosyl diacylglycerol and sulphoquinovosyl diacylglycerol lipids. The concentration of unsaturated C18 fatty acids was lower in the Mo-deficient cells. © 1993 Rapid Communications of Oxford Ltd.
Possibility of hydrological connectivity between Manasarovar Lake and Gangotri Glacier
(Indian Academy of Sciences, 2019) S.P. Rai; D. Singh; R. Saini; D.S. Rathore; S. Kumar; S.K. Jain; N. Pant
Considering the hydrological and religious significance of the Ganga River and the Manasarovar Lake in India, the present study has been devised to investigate the data related to the place of origin of the Ganges and to investigate the likely connection between waters of the two systems. Satellite data was employed to develop maps and find out the possibility of surface connectivity, whereas isotopic and chemical data, obtained from the field samplings and the published research literatures were used to investigate the possibility of subsurface connectivity of the Gangotri Glacier water with that of the Manasarovar Lake. Topographically, both the water systems are located in different catchment zones, separated by high mountain ridges; rejecting any possibility for the surface connectivity. Similarly, there are significant variations in isotopic and physiochemical properties of the water, suggesting no possibility of surface or sub-surface connectivity between water of the two systems. © 2019, Indian Academy of Sciences.
