| Abstract | Highlights Four different kinds of prehydrolysis methods were tested for their effect on delignification ability and The pre-hydrolysis steps were found effective in disruption of lignocellulosic matrix which enhanced the delignification and enzymatic hydrolysability of empty palm fruit bunch (EFBTypha capensis with its plenteous availability, high biomass productivity, invasive nature, easier delignification (high S/G ratio and low repolymerization of lignin) and enzymatic hydrolysability deserved a promising feedstock for bioconversion processes.Miscanthusx giganteus, Typhato assess the effect of different prehydrolysis methods in combination with organosolv delignification process. Four prehydrolysis methods (dilute acid prehydrolysis, autohydrolysis, enzymatic prehydrolysis and soda prehydrolysis) were assessed for their efficacy of enhancing delignification and enzymatic hydrolysability.It has been unveiled that prehydrolysis of delignificationin subsequent ethanol organosolv process and exhibited significantly higher enzymatic hydrolysability of the cellulosic pulp suggesting that twonecessary and commendable. The delignification was improved on addition of aromatic scavengers which arebelieved to On the contrary, two-step pretreatment process proved nonthe delignification and enzymatic hydrolysability of revealing that single step prehydrolysis or organosolv process better suited. NMR, FTIR and GPC analysis of herbaceous lignin, relatively verybehavioural differences of Typhaproductivityand obnoxious nature,digestibility established Typhasector. |
