초록
<P>Lignin S/G ratio has been investigated as an important factor in biomass recalcitrance to bioethanol production. Because of the complexity and variety of biomass, recalcitrance was also reportedly influenced by several other factors, such as total lignin content, degree of cellulose polymerization, etc. In addition, the effect of S/G ratio on biomass conversion is not uniform across plant species. Herein, 11 <I>Populus trichocarpa</I> natural variants grown under the same conditions with similar total lignin content were selected to minimize the effects of other factors. The lignin S/G ratio of the selected <I>P. trichocarpa</I> natural variants showed negative correlations with <I>p</I>-hydroxybenzoate (PB) and β–5 linkage contents, while it had positive ones with β-<I>O</I>-4 linkage, lignin molecular weight, and ethanol production. This study showed the importance of lignin S/G ratio as an independent recalcitrance factor that may aid future energy crop engineering and biomass conversion strategies.</P><P>Impact of lignin S/G ratio in <I>Populus trichocarpa</I> on its structural characteristics and bioethanol production was understood by NMR and Py-MBMS analyses.</P><P><B>Graphic Abstract</B><BR><IMG SRC='http://pubs.acs.org/appl/literatum/publisher/achs/journals/content/ascecg/2018/ascecg.2018.6.issue-2/acssuschemeng.7b03586/production/images/medium/sc-2017-03586u_0007.gif'></P><P><A href='http://pubs.acs.org/doi/suppl/10.1021/sc7b03586'>ACS Electronic Supporting Info</A></P>
