The Efficiency of Using Oil Palm Frond Hydrolysate from Enzymatic Hydrolysis in Bioethanol Production

Effects of Enzyme Volumes on Hydrolysis and Fermentation for Ethanol Production From Leftover Cooked Rice

“…The highest RS obtained for V1–V3 were 18.7, 23.2, and 34.6 g/L, respectively. This result was similar to Farah Amani ( Farah Amani et al, 2017 ) who reported that the rate of hydrolysis enhanced with increasing of enzyme volumes used. The kinetic models for enzyme volumes and COD/RS were shown in Table 2 .…”

“…Its nutrients were analyzed and showed in Table 1 . The LCR was first ground into the smaller size by the blender and then used for enzymatic hydrolysis ( Farah Amani et al, 2017 ). Different from complex substrates (such as food waste), a combination enzymes (protease and cellulase) are not necessary in this study to break the LCR into fermentable sugars.…”

Emerging technologies for value-added use of oil palm biomass

“…Therefore, these findings suggested that better performance of SSF was achieved over the SHF process. Another study by Farah Amani et al 131 utilized OPF hydrolysate (63.7% cellulose, 21.9% hemicellulose, and 14.4% lignin) for bioethanol production. The enzymatic hydrolysis of pretreated OPF was carried out using 40 U per g of cellulase and 10 U per g of hemicellulase at 50 °C for 150 min, resulting in the maximum yield of 2421 μg g −1 and 2418 μg g −1 of glucose and xylose, respectively.…”

A New Multi-Stress Resistant Wickerhamomyces Anomalus: Isolation, Identification and Bioethanol Fermentation Potential

“…The process includes pretreatment of biomass, production of recombinant cellulase enzymes through a chain of procedures, saccharification, and conversion of sugars to ethanol. Additionally, the conversion of lignocellulosic hydrolysate into bio-ethanol by employing effective yeast strain is a hallmark in bioethanol production and is also the area of prime interest nowadays (Amani et al, 2017). Moreover, Saccharomyces cerevisiae (Brewer's yeast) is well known for its ability to convert fermentable sugars, particularly hexoses to ethanol, and is therefore employed widely in industries (Cunha et al, 2017).…”
