2,3-Butanediol (2,3-BD) can be produced from simultaneous saccharification and fermentation of liquefied cassava powder using Klebsiella oxytoca. As the performance of filtration in downstream processes can be reduced by insoluble solid, the insoluble solid content should be minimized. Characterization of cassava powder and its liquefied solution was carried out to investigate if insoluble solid can be reduced after liquefaction process. Cassava powder showed wide size distribution between 0.4 ~ 1,700 ㎛ and particles less than 45 ㎛ comprised about 54 wt%. Sugar contents inversely increased with particle size and reduction of solid contents after liquefaction was inversely proportional to the sugar content trend. Ruling out particle larger than 600 ㎛ can be reasonable choice to reduce solid contents.
