How cell wall complexity influences saccharification efficiency in Miscanthus sinensis.

De Souza AP, Alvim Kamei CL, Torres AF, Pattathil S, Hahn MG, Trindade LM, Buckeridge MS - J. Exp. Bot. (2015)

Bottom Line: However, one of the key barriers to producing bioethanol is the lack of information about cell wall structure.Cell walls are thought to display compositional differences that lead to emergence of a very high level of complexity, resulting in great diversity in cell wall architectures.When saccharification efficiency was correlated negatively with lignin, the structural features of arabinoxylan and xyloglucan were found to contribute positively to hydrolysis.

Cell wall extracts yield (%) of three different genotypes (H0120, H0116, and H0198) of Miscanthus sinensis. Different letters indicate statistically significant differences (n=5). (This figure is available in colour at JXB online.)

Figure 2: Cell wall extracts yield (%) of three different genotypes (H0120, H0116, and H0198) of Miscanthus sinensis. Different letters indicate statistically significant differences (n=5). (This figure is available in colour at JXB online.)

Mentions: Genotype H0198 had a lower hemicelluloses content (5.5%) in its cell walls than did the other two genotypes, H0120 and H0116 (Fig. 1A). This same trend was observed in wall fraction yields for H0198, where the 0.1M and 1M NaOH extracts yielded less material, although the difference between H0198 and H0120 was not significant (Fig. 2). The H0120 genotype had ~2.3% lower cellulose content than H0198 (Fig. 1B). Similarly, the yield of residue from the fractionation procedure of this genotype showed a tendency to be lower than H0116 and H0198. The ammonium oxalate extract of H0120 was significantly higher (Fig. 2), suggesting that this genotype is composed of a higher proportion of soluble polysaccharides than H0116 and H0198.
