Abstract
Attention was devoted to the delignification of the crude bagasse (CB) and cotton stalks (CS) by cheap commercial sodium hypochlorite solution.
Optimum delignification of these substrates was achieved by treatment with 0·7 g Cl g−1 substrate (pH 7·0) for 20 h at room temperature, with a solid: liquid (S:L) ratio 1:20.
The delignified CB and CS were saccharified with an enzyme preparation from a potent local mutant of Trichoderma viride (253-M16). A satisfactory saccharification was obtained with most of the treatments used. The highest conversion yield (93%) was recorded with CB treated with sodium hypochlorite solution (S:L ratio 1:20), followed by NaOH (0·05 m).
