“…Moreover, the acidic nature of water at elevated temperatures might contribute to the breakdown of OPEFB into other compounds. This aligns with previous studies on hot-compressed water pre-treatment of OPEFB [20].…”

The palm oil industry plays a vital role in Malaysia, but it generates substantial amounts of biomass waste, which, if not properly managed, can lead to environmental pollution. Among these waste products, oil palm empty fruit bunch (OPEFB) is the most abundant and underutilized, being generated daily without any commercial value. The aim is to efficiently convert OPEFB into fermentable sugars for improved biogas production. Nevertheless, the challenge lies in efficiently degrading OPEFB within a short timeframe before fermentation into biogas can occur. This study aims to explore the potential of hydrothermal pre-treatment as a means to enhance biogas production from OPEFB. The pre-treatment process was optimized by varying reaction temperatures (100 to 250°C), and reaction times (10 to 40 minutes). The main objective was to maximize the total soluble sugar yield, a crucial precursor for efficient biogas production. The optimal conditions for hydrothermal pre-treatment are identified at a temperature of 175°C and a reaction time of 20 minutes, resulting in a yield of 49.2 mg of glucose per gram of OPEFB. Subsequent anaerobic co-digestion of the treated OPEFB with digested sludge increased methane yield to 100.53 ml/g-VS, representing a remarkable 392% increase compared to the low 20.44 ml/g-VS produced by untreated OPEFB. Nonetheless, elevated pre-treatment temperatures (200°C and above) led to reduced biogas production due to inhibitory compounds. This study demonstrates the effectiveness of hydrothermal pre-treatment as a low-temperature, green technology for enhancing OPEFB-based biogas production, contributing to Malaysia's renewable energy goals. Future research should focus on scale-up and validation of this integrated process.

“…The hydrolysis reaction was conducted using crystalline cellulose (1 g) in an aqueous sodium acetate buffer solution (60 mL), as Matsumura et al reported that real biomass samples (e.g., eucalyptus and palm oil empty fruit bunch) exhibited different glucose production characteristics 1) . As such, a fundamental study employing pure cellulose is carried out herein.…”

“…In this context, lignocellulosic materials from agricultural and forest residues, such as rice straw, sawdust, and palm oil empty fruit bunch, have attracted growing attention as alternative feedstocks for bioethanol production, as they are both abundant and unutilized 1) . In the case of lignocellulosic materials, the cellulose present in these materials can be hydrolyzed to give glucose, which can then be employed as a substrate for ethanol fermentation.…”

We herein report the first study into the use of an enzyme mixture of cellulase and β-glucosidase for cellulose hydrolysis, with the overall aim of expressing the effect of β-glucosidase addition using a simple equation. To achieve this goal, different amounts of commercial cellulase and β-glucosidase were added to a cellulose slurry, and hydrolysis experiments were carried out at 40 and 50 over 0-48 h in a shaker incubator using a 0.1 mol/ dm 3 sodium acetate solution to maintain a solution pH of 5. The glucose yield got higher for the larger amount of cellulase and larger amount of β-glucosidase. The yield of glucose recovered at 50 was lower than that recovered at 40 . Finally, an equation to estimate glucose production using such a cellulase and β-glucosidase mixture was then developed for the first time, and this equation correlated well with the experimental data. The obtained equation expressed the hydrolysis using another bottle of cellulase, too.
