“…Low F v /F m values (60.2) point to a severe stress in the culture. The population growth rate was zero or the cell number in the population started to decrease which means expiry of photoplankton cells (Voronova et al, 2009). (F v /F m ) yields showed high percent of reduction in natural sedimentation samples.…”

“…Microalgae hold the essential pigment and protein to keep the cell alive under N-deprived conditions, and wait for the nitrogen source replenishing to the environment. Once the nitrogen replenishing to the environment, the enhancement of the growth rate (Voronova et al, 2009) and the inorganic carbon assimilation rate (Livne and Sukenik, 1992) have been observed. However, the effects of N-deprived conditions and resupplying the nitrogen source to the cultivation system on the biomass yield, CO 2 fixation rate, and the bioenergy yield of the thermophilic cyanobacteria have not been investigated.…”

Nitrogen availability directly affects the microalgal metabolism. A thermophilic cyanobacterium named Thermosynechococcus CL-1 was cultivated in a continuous system to evaluate the effects of NO 3 -fluxes on the biomass production, bioenergy production, and CO 2 fixation. The results show that decreasing the NO 3 -flux to a N-deprived level (1.01 mM/d) enhances the carbohydrate content in TCL-1 to 45%, accompanied by a decrease in the lipid content. However, increasing the NO 3 -flux from a N-deprived level (1.01 mM/d) decreases the carbohydrate content dramatically, accompanied by a slight increase in the lipid content. No matter whether the NO 3 -flux decreases from a N-replete level (8.35 mM/d) to a N-deprived one (1.01 mM/d), or increases from a N-deprived level to higher one, the peak biomass yield occurs at the same NO 3 -flux level, 4.18 mM/d. In addition, the peak lipid yield, carbohydrate yield, and CO 2 fixation rate were recorded at 482 and 660 mg/L/d, and 3.9 g/L/d, respectively, under the same NO 3 -flux level (4.18 mM/d). Although cultivating TCL-1 under the 4.18 mM/d NO 3 -flux level exhibits great biomass production, CO 2 fixation, and bioenergy production potential, different procedures (the NO 3 -flux decreasing from the N-replete level and the NO 3 -flux increasing from the N-deprived level) could influence the final quantity of bioenergy production and CO 2 fixation. The NO 3 -flux, NO 3 -concentration in the bioreactor, and the NO 3 -flux variation routes are all important factors to determine the nitrogen availability of TCL-1 in continuous cultivation.
