Summary: Lignocellulosic biomass is an abundant material on earth and can be processed by microorganisms to produce biofuels. Saccharomyces cerevisiae is an ideal candidate for consolidated bio-processing (CBP) to produce cellulose-based ethanol. However, there are still challenges in the process, such as incomplete substrate catabolism and low expression of heterologous proteins.

Summary: Kenaf, an annual fiber crop mainly grown in India and China, is emerging as a promising bio-based energy source due to its rapid growth, CO2 absorption capabilities, and high productivity. The study evaluated 10 different cultivars of kenaf for cellulosic ethanol production, finding that ethanol yield and productivity were significantly impacted by cultivar type, rather than biomass composition. Engineering yeast to utilize xylose under pH control can maximize ethanol production from kenaf.

Summary: The effects of switchgrass particle sizes on the effectiveness of H2SO4 and NaOH pretreatments were investigated. Increasing particle size led to higher contents of glucan, xylan, and lignin in raw switchgrass. SEM images and FTIR spectra showed no visible variations in microstructures and chemical bonds among different particle sizes under the same pretreatment conditions. The optimal ethanol conversion performance depends on the interaction between the pretreatment method and biomass particle size.

Summary: Second-generation biofuels derived from lignocellulosic biomass are considered renewable alternatives to fossil fuels with lower environmental impact and potentially higher supply and energy security. This study examines the economic and environmental performance of second-generation bioethanol production from corn stover in the European Union (EU), focusing on different pretreatment technologies. The findings reveal that the choice of pretreatment technology has a location-dependent impact on the economic and environmental outcomes, which should be taken into consideration by decision-makers not only in the EU but also in other regions.

Summary: The aim of this study is to efficiently produce xylanase from agro-industrial waste. The culture conditions for three strains of Aspergillus fumigatus were optimized, and the most prolific strain produced the highest xylanase activity at pH 9.0 and 30°C using yeast extract as a nitrogen source. Wheat bran was found to be the most fermentable material, yielding 66.0 U/gds of xylanase. The synthesized xylanase displayed maximum activity at pH 6.0 and 45°C, with a strong affinity for birchwood xylan as opposed to other substrates.

Summary: Co-processing residue with stabilized bio-oil in a hydrotreater can convert a significant amount of residue to lighter products without affecting bio-oil conversion rate, potentially due to synergy between hydrotreating and hydrocracking reactions. Elimination of a separate hydrocracker and recycling of residue to the hydrotreating reactor can lead to a 6% reduction in conversion cost, with 57% of the cost reduction attributed to capital equipment elimination and 43% to lower operating costs.

Summary: This paper describes the techno-economic assessment of producing hydrocarbon fuels from corn stover-derived ethanol, considering multiple scenarios including co-producing higher-value compounds. The results suggest that the hydrothermal liquefaction process of the residual lignin has significant cost advantages compared to burning. Conversion of ethanol to butanol also shows favorable economics, while the economic performance of butadiene process is influenced by market prices.

Summary: This study investigated the oxidative depolymerisation mechanism of lignin by PAA, revealing that PAA initiates oxygen insertion to the lignin macromolecule resulting in disruption of its packing structures and facilitates depolymerisation. The predominant reaction pathway for the oxidative depolymerisation of lignin with PAA was found to be the Baeyer-Villiger oxidation. The research also explored various metal oxide and mixed metal oxide catalysts to enhance the efficiency of PAA-mediated depolymerisation of lignin.

Summary: Electrochemical water splitting is crucial for hydrogen production, and improving the hydrogen separation rate from the electrode is essential for enhancing water electrolyzer performance. However, issues such as air bubble adhesion to the electrode plate hinder the process. Therefore, a methodology to investigate the two-phase flow within the electrolyzer is in high demand. This study proposes using a microfluidic system as a simulator for the electrolyzer and optimizing the two-phase flow by manipulating the micro-structure of the flow.

Summary: In this study, a novel hybrid Quantile Regression (QR) model is proposed for Probabilistic Load Forecasting (PLF). The model integrates causal dilated convolution, residual connection, and Bidirectional Long Short-Term Memory (BiLSTM) for multi-scale feature extraction. In addition, a Combined Probabilistic Load Forecasting System (CPLFS) is proposed to overcome the inherent flaws of relying on a single model. Simulation results show that the hybrid QR outperforms traditional models and CPLFS exceeds the best benchmarks in terms of prediction accuracy and stability.
