Pressurized pretreatment and simultaneous saccharification and fermentation with in situ detoxification to increase bioethanol production from green coconut fibers

In this study, we investigated four conventional pretreatments under pressurized conditions, as well as in situ detoxification using polyethylene glycol (PEG 400), for the simultaneous saccharification and fermentation (SSF) of green coconut fibers. The highest fermentable sugar production (22.05% g...
