Fig. 3From: Direct and highly productive conversion of cyanobacteria Arthrospira platensis to ethanol with CaCl2 additionEffects of lysozyme and CaCl2 on glycogen extraction from A. platensis. Glucose concentrations in supernatant of the cell slurry of A. platensis in the presence of α-amylase and glucoamylase with neither lysozyme nor CaCl2 (black cross), lysozyme (blue square), CaCl2 (light blue triangle), and both lysozyme and CaCl2 (red circle) at 40 °C. Error bars indicate the SD of three replicated experiments. For some data points, error bars obtained by three replications are smaller than the symbolsBack to article page
