Fig 4

Biomass loss (grey) after each treatment (x-axis) and measured protein (blue) and carbohydrate (green) content in the supernatant referred to initial biomass (y-axis). AmOx: c(di-ammonium oxalate) = 20 mmol L-1, pH = 4, T = 70°C, t = 1 h. 0.1 M NaOH: c(NaOH) = 0.1 mol L-1, T = 22°C, t = 24 h. 4.4 M NaOH: c(NaOH) = 4.4 mol L-1, T = 22°C, t = 8 h. H2SO4: 72% H2SO4, T = 22°C, t = 1 h, followed by dilution with water to 4% H2SO4, T = 100°C, t = 1 h. n = 3.
