Abstract. Yudianto D, Nainggolan EA, Millati R, Hidayat C, Lennartsson P, Taherzadeh MJ, Niklasson C. 2019. Bioconversion of pretreated wheat straw to ethanol by Monascus purpureus CBS 109.07 and Fusarium venenatum ATCC 20334 using simultaneous saccharification and fermentation. 20: 2229-2235. Fractions of sulfuric acid-pretreated wheat straw, i.e. solid, liquid, and a mixture of liquid and solid were used as substrates in simultaneous saccharification and fermentation (SSF) process to produce ethanol. The bioconversion was performed by Monascus purpureus CBS 109.07 and Fusarium venenatum ATCC 20334. The highest ethanol yields from solid, liquid and a mixture of solid and liquid fractions by M. purpureus CBS 109.07 were 0.36, 0.41, and 0.37 g/g glucose, respectively. The corresponding values by F. venenatum ATCC 20334 were 0.21, 0.54, 0.35 g/g glucose, respectively.

The alkaline-pretreated wheat straw was used as raw materials, and the fed-batch simultaneous saccharification and fermentation (SSF) process for ethanol production with higher substrate loading (up to 16% (w/v)) was investigated. Firstly, the Fed-batch SSF with different feeding strategy was optimized. The highest ethanol concentration reached to 37.9 g/L with an initial substrate loading of 10% (w/v), and equal substrate addition (3%) at 8h and 16h respectively. Then the effects of Tween-20 were also investigated. The results showed that Tween-20 addition with 2.0 g/L can improved the ethanol production. Furthermore, a nonisothermal fed-batch SSF was proposed, and the ethanol concentration of 41.5 g/L, corresponds to 81.0 % of the theoretical yield was achieved within 72 h.
