Abstract

Untreated and alkali-treated samples of sugarcane bagasse (48-100 mesh size) were dissolved in alkaline iron tartrate solution FeTNa) at different solute-to-solvent (STS) ratios. The concentration of dissolved cellulose was maximal at 0.5/20 5T5 ratio for both samples and was equal to 0.70%. The extent of solubill-station was highest, namely 30%, at ITS ratios of 0.3/20 and 0.5/20 for untreated and treated samples, respectively. Although alkaline treatment changed the shape of the solubility curve. it did not significantly improve solubillization of bagasse in FeTNa.

Partially-milled sugarcane stalks from the first, the second, and the third mill were ground to 48 mesh site and treated with crude cellulose from Trichoderma viride 1TCC-1433. The concentrations of sucrose and reducing sugars in extracts of cellulose-treated and untreated stalks were the same within experimental error.
