Readily-milled fraction of wet sugarcane bagasse as an advanced feedstock for monosaccharide production via the RT-CaCCO process

The RT-CaCCO process for enzymatic saccharification was applied to readily-milled fractions of wet sugarcane bagasse. Wet bagasse immediately after juice extraction was crushed with shark-mill blades to prepare two fractions referred to as readily-milled (RF) and hardly-milled fraction (HF). Monosaccharide recoveries from RFs via the RT-CaCCO process were 1.03–1.21 times higher than those from HFs. Moreover, when the wet weight ratio of RF/HF was adjusted to 2/8, the hexose recovery from RF was 90.9%, which was 1.3 times higher than that of the wet bagasse before fractionation. The results show that this process can be used for efficient monosaccharide recovery from RF of wet bagasse. In addition, the process can be adapted to more fibrous HF for multiple uses such as fuel for boilers and fibers for particleboards.
