Evaluation of Chlorella (Chlorophyta) as Source of Fermentable Sugars via Cell Wall Enzymatic Hydrolysis

Figure 3

Effect of biomass pretreatment on hydrolyzed sugar yields for C. homosphaera and C. zofingiensis. Cells pellet were resuspended in citrate buffer pH 4.8 and subjected to enzymatic hydrolysis (blue and orange bars) or washed twice with chilled ethanol 95% (v/v), cold dried and ground, and then subjected to enzymatic hydrolysis in citrate pH 4.8 buffer (green and red bars). Hydrolyzed glucose (blue and green bars) and total reductant sugars (orange and red bars) were determined.
