Viscosity reduction has a great impact on the efficiency of ethanol production when using roots and tubers as feedstock. Plant cell wall-degrading enzymes have been successfully applied to overcome the challenges posed by high viscosity. However, the changes in cell wall polymers during the viscosity-reducing process are poorly characterized. Comprehensive microarray polymer profiling, which is a high-throughput microarray, was used for the first time to map changes in the cell wall polymers of sweet potato (Ipomoea batatas), cassava (Manihot esculenta), and Canna edulis Ker.over the entire viscosity-reducing process. The results indicated that the composition of cell wall polymers among these three roots and tubers was markedly different. The gel-like matrix and glycoprotein network in the C. edulis Ker. cell wall caused difficulty in viscosity reduction. The obvious viscosity reduction of the sweet potato and the cassava was attributed to the degradation of homogalacturonan and the released 1,4-β-D-galactan and 1,5-α-L-arabinan. C 2015

“…Another bottleneck is the feedback inhibition of cellobiose on fermentation process after hydrolysis during bioethanol production (Guan et al, 2013 ; Ha et al, 2013 ; Cheng et al, 2015a , b ). The most effective method to solve the feedback inhibition problem is simultaneous saccharification and fermentation (SSF), a process in which enzymatic process hydrolyzes lignocelluloses to sugars and ferments to bioethanol simultaneously, being already used in many lignocelluloses fermentation systems (Huang et al, 2013 ; Soares and Gouveia, 2013 ). However, there is no detail report on SSF process using water hyacinth as substrate.…”

Water hyacinth was used as substrate for bioethanol production in the present study. Combination of acid pretreatment and enzymatic hydrolysis was the most effective process for sugar production that resulted in the production of 402.93 mg reducing sugar at optimal condition. A regression model was built to optimize the fermentation factors according to response surface method in saccharification and fermentation (SSF) process. The optimized condition for ethanol production by SSF process was fermented at 38.87°C in 81.87 h when inoculated with 6.11 ml yeast, where 1.291 g/L bioethanol was produced. Meanwhile, 1.289 g/L ethanol was produced during experimentation, which showed reliability of presented regression model in this research. The optimization method discussed in the present study leading to relatively high bioethanol production could provide a promising way for Alien Invasive Species with high cellulose content.

“…The traditional method of adding much more water to the mash is not an effective way to solve the actual problem. Commercial plant cell wall–degrading enzymes (PCWDEs), such as xylanase , cellulase, pectinases, and hemicellulases , acid xylanase, and β‐glucanase , are able to reduce the mash viscosity. Most of these commercial enzymes are produced by fungi .…”

Penicillium ochrochloron Biourge, which was isolated from rotten sweet potato, can produce plant cell wall-degrading enzymes (PCWDEs) with high viscosity reducing capability for ethanol production using fresh sweet potato tubers as feedstock. The enzyme preparation was characterized by a broad enzyme spectrum including 13 kinds of enzymes with the activity to hydrolyze cellulose, hemicellulose, pectin, starch, and protein. The maximum viscosity-reducing capability was observed when the enzyme preparation was obtained after 5 days of fermentation using 20 g/L corncob as a sole carbon source, 4.5 g/L NH 4 NO 3 as a sole nitrogen source, and an initial medium pH of 6.5. The sweet potato mash treated with the enzyme preparation exhibited much higher fermentation efficiency (92.58%) compared with commercial cellulase (88.06%) and control (83.5%). The enzyme production was then scaled up to 0.5, 5, and 100 L, and the viscosity-reducing rates were found to be 85%, 90%, and 91%, respectively. Thus, P. ochrochloron Biourge displays potential viscosity-reducing capability for ethanol production.
