The effects of UV-B and pesticides (Butachlor and Carbofuran) on nitrogen and phosphorus metabolism have been studied on filamentous, nitrogen-fixing cyanobacterium, Anabaena doliolum. The study showed a decrease in the uptake of NH4+, PO4-3, activities of nitrogenase, glutamine synthetase, and alkaline phosphatase, when the cells were exposed to UV-B and pesticides. The interaction of two stresses showed the additive type of behavior for the studied parameters. In contrast, a significant increase in NO3- uptake and nitrate reductase activity was seen when Anabaena cells were exposed to different doses of UV-B.
