Summary: This research investigated the enhanced efficiency of enzymatic hydrolysis of wheat straw through freeze-thaw pretreatment and analyzed the changes in physicochemical structure after pretreatment. The study found that cellulose and hemicellulose hydrolysis efficiency was improved, with hemicellulose being more susceptible to pretreatment. The highest hydrolysis efficiency for cellulose and hemicellulose was 57.06% and 70.66%, respectively, achieved at -80℃ for 24 hours and -10℃ for 24 hours, which were 2.23 and 3.13 times higher than the control levels, respectively. The study also observed cracks and holes in the pretreated samples, indicating structural changes. Fourier transform infrared spectroscopy and X-ray diffraction analysis revealed disruptions in the crystalline and amorphous regions and hydrogen bonds. This study provides a physical pretreatment method for enhancing the enzymatic hydrolysis efficiency of wheat straw.

Summary: This study developed a novel biorefinery method for waste wheat straw, in which a natural surfactant humic acid was used during acidic pretreatment to enhance enzymatic saccharification efficiency. The success of enzymatic digestion was attributed to improved accessibility of cellulose to cellulase and structural changes in lignocellulose. These findings suggest that humic acid may be a beneficial surfactant in biorefinery processes and could potentially inspire research into other natural surfactants.

Summary: In this study, wheat straw was pretreated with a combination of ball milling (BM) and NaAlO2 particles (NaAlO2-BM) for efficient enzymatic hydrolysis. The results showed that NaAlO2-BM pretreatment significantly reduced particle size to tissue scale within 10 minutes, with 0.5 times lower energy consumption compared to BM pretreatment. The 20-minute NaAlO2-BM pretreatment achieved a glucose yield of 95.4% and the highest energy efficiency of 0.121 kg glucose/kWh, increasing by 1.1 times than BM pretreatment. Energy consumption was positively correlated with cellulose content and negatively correlated with particle size, cellulose crystallinity, and energy efficiency. The combination of BM and NaAlO2 particles proved to be a promising pretreatment approach for glucose production and improving energy efficiency during lignocellulosic hydrolysis.

Summary: This study analyzed the genetic gains of winter wheat adapted to the Northern Great Plains of North America using long-term data. The results showed a decline in relative grain yield in recent years and limited genetic progress. The study suggests that winter wheat in this region has reached its yield potential and may be limited by environmental factors such as global warming.

Summary: Gasification kinetics of six chars from residual origin were studied under relatively low temperature, low CO2, and high H2O partial pressures. The Random Pore Model (RPM) showed the best fit to experimental results, but the selection of the reaction model depended on the ash composition, specifically the presence of alkali and alkaline earth metals. Chars with ash content higher than 30% wt. were modeled with the RPM model, while chars with the highest K/Si ratio required modified versions of the RPM to accurately predict reaction rates. Textural properties played a key role in determining reaction parameters, such as the pre-exponential factor and activation energy, for chars with similar ash content and composition.
