abstract = {Biomass from perennial plants can be considered a
carbon-neutral renewable resource. The tall wheatgrass
hybrid Szarvasi-1 (Agropyron elongatum, hereafter referred
to as “Szarvasi”) belongs to the perennial Poaceae
representing a species, which can grow on marginal soils and
produce large amounts of biomass. Several conventional and
advanced pretreatment methods have been developed to enhance
the saccharification efficiency of plant biomass. Advanced
pretreatment methods, such as microwave-assisted
pretreatment methods are faster and use less energy compared
to conventional pretreatment methods. In this study, we
investigated the potential of Szarvasi biomass as a
biorefinery feedstock. For this purpose, the lignocellulosic
structure of Szarvasi biomass was investigated in detail. In
addition, microwave-assisted pretreatments were applied to
Szarvasi biomass using different reagents including weak
acids and alkali. The produced pulp, hydrolysates, and
extracted lignin were quantitatively characterized. In
particular, the alkali pretreatment significantly enhanced
the saccharification efficiency of the pulp 16-fold compared
to untreated biomass of Szarvasi. The acid pretreatment
directly converted $25\%$ of the cellulose into glucose
without the need of enzymatic digestion. In addition, based
on lignin compositional and lignin linkage analysis a lignin
chemical model structure present in Szarvasi biomass could
be established.},
