Ethanol production from a high concentration of A. platensis biomass in the presence of lysozyme. a Ethanol production in the presence of 1 g L⁻¹ lysozyme (solid line) and the absence of lysozyme (dotted line) at 38 °C (blue triangle) and 40 °C (red circle). b Glycogen consumption in the presence of 1 g L⁻¹ of lysozyme at 38 °C (blue triangle) and 40 °C (red circle). Error bars indicate standard deviations (SD) of three replicated experiments. For some data points, error bars obtained by three replications are smaller than the symbols
