Última Bio-physiological response of biofilter algal candidate Ulva sp. to different nitrogen forms and fluxes ArchiMer Moustafa, Yasser T. A.; Bougaran, Gael; Callier, Myriam; Blancheton, Jean-paul. The present study was carried out to study the long term effect of different nitrogen forms and concentrations (14.3, 28.6 and 57.1 µM N-NH4 and 214, 2360 and 3700 µM N-NO3) on the photosynthesis and relative growth rate (RGR) of Ulva sp. for five weeks. Nutrient-enriched seawater was supplied at an exchange rate of between 12.6 and 14.4 volumes per day. Relative growth rate was determined weekly. Photosynthetic oxygen evolution response was measured using 20 - 25 mg fresh weight seaweed incubated in a DW3 measuring chamber for 56 min under different irradiances with light and dark periods alternating every seven minutes. Photosynthetic light-response curves were drawn using 15 photosynthetic oxygen evolution readings normalized to dry weight. Experimental...
