PRODUCTION OF BIOETHANOL BY USING PRETREATED COCONUT HUSK AS CARBON SOURCE
Jun 23, 2023
In the current study, coconut husk, a lignocellulosic biomass, was employed as the
feedstock for production of bioethanol. The powderised coconut husks were
subjected to thermal pretreatment, chemical pretreatment and microwave-assistedalkaline (MAA) pretreatment prior to enzymatic and hydrolysis process

The composition profile of coconut husks was significantly altered upon the MAA pretreatment as compared to the untreated sample, with the cellulose content increasing from 18-21% to 38-39% while lignin content decreased from 46-53% to 31-33%. Enzymatic hydrolysis of MAA-pretreated coconut husk also achieved the highest yield of fermentable sugars (measured as glucose) with 0.279 g sugar/g coconut husk.
