Various factors affecting yields of Gal, AG, and 5-HMF formationduring saccharification were investigated using agar as a substrate in the presence of several bisulfate-based acidic ionic liquids as catalysts. The result was compared with employing sulfuric acid in saccharification from the viewpoint of sugar yields and 5-HMF formation. [Bmim][HSO4], [Hmim][HSO4], [Morph][HSO4], [Bu4N][HSO4], [Bu4P][HSO4], [Chol][HSO4] showed moderate to high yields of Gal and AG with a remarkable decrease in 5-HMF formation compared with sulfuric acid.
Among them, [Chol][HSO4] ionic liquid was found to exhibit the highest yield of sugars with an acceptable concentration of 5-HMF that does not inhibit the fermentation process.
