Lignocellulose (2nd generation) is difficult to hydrolyze due to the presence of lignin and the technology developed for cellulose fermentation to ethanol is not yet economically viable. Recent advances in the extremely new field of biotechnology for the ethanol production are making it possible to use of macro algal biomass, e.q., red algae, because of their several superior aspects as 3rd generation biomass; no lignin, high contents of carbohydrates as well as very fast-growing rate with the fixation of large amount of CO2, know as a green house gas. This article, as the basic study of saccharification to ethanol production from red algae, the properties and the optimum conditions of saccharification process were estibilshed. The important independent variable for saccharification process were selected as acid(H2SO4) concentration, reaction temperature, reaction time, and S/L ratio by batch reaction.
