Fig. 1From: Study of the growth and biochemical composition of 20 species of cyanobacteria cultured in cylindrical photobioreactorsIn a growth rate (d−1) and in b dry biomass (g L−1) for cyanobacterial strains as a function of experimental time. In b white bars represent biomass at 48 h and gray bars represent dry biomass at 144 h. Error bars represent the standard deviation from the mean (n = 3). The asterisk (*) indicates the highest value (ANOVA, p < 0.05)Back to article page
