Randomized trial compares carbohydrate solubilization in unpretreated sugarcane bagasse, indicating thermophilic bacteria may offer a more efficient alternative.
Key Points
This study aims to compare the effectiveness of thermophilic bacteria and fungal enzyme systems in solubilizing carbohydrates from unpretreated sugarcane bagasse.
Conducted a direct comparison of carbohydrate solubilization using thermophilic bacteria and a fungal cellulase system.
Assessed the effect of different particle sizes on carbohydrate solubilization.
Measured solubilization rates and established correlations between sugar types.
Carbohydrate solubilization was 1.9- to 3.7-fold higher with the thermophilic bacteria compared to the fungal system.
SSS showed a 2.2-fold decrease in solubilization for larger particle sizes, while CBP only showed a 0.52-fold decrease.
Residual sugar concentrations were similar between both systems despite differences in solubilization efficiency.
