In the original article, The figures caption was published incorrectly. The right figure captions are:

Fig. 4 Selectivity versus acid concentration at different temperature. The maximum sugars recovery is reported above the graph to be correlate with the selectivity. The best condition was considered 3% of acid concentration and 120 °C, in evidence

Fig. 5 Ethanolic fermentation from Chlorella hydrolyzed. RS: reducing sugars and X: yeast concentration

Fig. 6 Repetition of the acidic hydrolysis experiment at 120 °C using 3% of acid concentration. a Mass yield (white) and reducing sugars (black). b Protein (white) and ash (black) released in the liquid fraction (%)
