Abstract

Highlights: The first in-depth analysis of lignocellulose from common cattail was provided. A high amount of cellulose was measured in common cattail cell walls. A low index of crystallinity was measured for cattail lignocellulose. A high degree of arabinose-substitution in hemicelluloses was estimated. A high saccharification potential for common cattail lignocellulose was deduced. Abstract: Second generation bioethanol produced from lignocellulosic biomass is attracting attention as an alternative energy source. In this study, a detailed knowledge of the composition and structure of common cattail ( Typha latifolia L.) cell wall polysaccharides, obtained from stem or leaves, has been conducted using a wide set of techniques to evaluate this species as a potential bioethanol feedstock. Our results showed that common cattail cellulose content was high for plants in the order Poales and was accompanied by a small amount of cross-linked polysaccharides. A high degree of arabinose-substitution in xylans, a high syringyl/guaiacyl ratio in lignin and a low level of cell wall crystallinity could yield a good performance for lignocellulose saccharification. These results identify common cattail as a promising plant for use as potential bioethanol feedstock. To the best of our knowledge, this is the first in-depth analysis to be conducted of lignocellulosic material from common cattail.
