Enzymatic hydrolysis of sugarcane bagasse
is also a promising way to utilize lignocellulosic biomass
due to its mild reaction conditions and high sugar yield [35,36].
Compared with enzyme hydrolysis,
GVL assisted hydrolysis of sugarcane bagasse showed high sugar yield of 0.87 g/g,
which is comparable to that of enzyme hydrolysis [37].
Both the two hydrolysis process
could generate high concentration
of sugars with low level of inhibitors,
which would benefit microbial utilization.
However, high level of NaCl was introduced into sugarcane bagasse hydrolysate in present study,
resulting in poor fermentation performance when using high sugar concentration.
As high enzyme cost still impeded the development of biomass hydrolysis,
GVL/water solution could be a potential way to release sugars from biomass.
