The biochemical conversion of cellulosic biomass to ethanol, a promising alternative fuel, can be carried out efficiently and economically using the simultaneous saccharification fermentation (SSF) process. SSF integrates enzymatic hydrolysis cellulose glucose, catalyzed by synergistic action cellulase beta-glucosidase, with fermentative synthesis ethanol. Because step determines availability glucose ethanologenic fermentation, kinetic beta-glucosidase susceptibility two enzymes inhibition...

Chemical activation was employed to convert algal biochar obtained from hydrothermal carbonization of lipid-extracted algae (LEA) activated carbon. Potassium hydroxide, previously utilized on cellulosic biomass but not biomass, as activating agent and the impact conditions, namely temperature, time, amount agent, were investigated. The yield carbon ranged 28% 52 % decreased temperature raised 400 600 °C, residence time 30 60 min, KOH/biochar mass ratio 0.25 1.0. In contrast, surface area...
