Fig. 2From: Filamentous cyanobacteria triples oil production in seawater-based medium supplemented with industrial waste: monosodium glutamate residueProtein (A) and carotenoids and phytols (B) accumulation for Spirulina subsalsa grown in mZM and in seawater supplemented with MSGR in different volume ratios (1/1000, 1/500, 1/200, 1/100 and 1/50, VMSGR/Vseawater). The red line stands for a protein content of 55% from food standard GB 16919 [28]. All data are averages of biological triplicates ± standard deviation. *Data for a given parameter followed by different letters are significantly different by Duncan’s test at p < 0.05Back to article page
