Nostoc muscorum and Phormidium foveolarum differentially respond to butachlor and UV-B stress

Present study deals with responses of two cyanobacteria viz. Nostoc muscorum and Phormidium foveolarum against butachlor [2-chloro-2,6-diethyl-N-(butoxymethyl) acetanilide] (low dose; 5 µg mL−1 and high dose; 10 µg mL−1) and UV-B (7.2 kJ m−2) alone, and in combination. Butachlor and UV-B exposure, alone and in combination, suppressed growth of both the cyanobacteria. This was accompanied by inhibitory effect on whole cell oxygen evolution and...
