Summary: This study investigates the optimal conditions for producing H2-rich fuel gas from canola hull pellets using supercritical water gasification. Temperature was found to be the most important parameter, followed by biomass-to-water ratio and residence time. The highest H2 yield of 3.43 mol/kg was achieved at 575 degrees C, 45 min, and a biomass-to-water ratio of 1:20. Comparative evaluation showed that torrefaction treatment significantly enhanced gas yield and composition. Hydrochar produced at higher temperatures had better quality.

Summary: Attrition ball-mill pretreatment of food waste showed improvements in particle size uniformity, soluble chemical oxygen demand (SCOD), biochemical methane potential, and total volatile fatty acids. Increasing milling speed and time led to higher SCOD and methane production, but extended milling time did not significantly improve the methane yield. Additionally, the microbial community analysis revealed a shift towards acetoclastic methanogens dominance and higher relative abundance of hydrogenotrophic methanogens in the pretreated samples.

Summary: An improved silica extraction process from rice husk was developed using a two-stage continuous method, involving attrition ball milling and alkaline leaching. The optimum conditions for the continuous process were determined through investigations on alkaline leaching parameters. NaOH was found to yield slightly more silica compared to KOH. The two-stage continuous extraction process operated stably for 80 hours with an 89% silica yield, with the optimal conditions of 0.2 M reaction concentration, 80 degrees C temperature, 3 hours duration time, and 6% (w/v) solid content.

Summary: Plastic pollution, particularly from PET, is a significant environmental challenge. This study investigates the enzyme kinetics of PET degradation and finds that the degree of crystallinity (X-C) has a substantial impact on the enzymatic reaction rate. The mobile amorphous fraction (X-MAF) is a better descriptor for the rate of enzymatic degradation. The longer lag phase observed with increased X-C is proposed to be due to increased substrate entanglement density and unproductive enzyme binding to the crystalline regions of PET.

Summary: Bacillus licheniformis 2709 is an important industrial producer of alkaline protease (AprE), and this study identified the UP elements of the aprE gene and demonstrated the lack of significant effect of CggR, FruR, and YhcZ transcription factors on aprE expression. Enhanced aprE expression and enzyme activity were achieved by deleting a negative regulatory factor binding site in the genome. These findings provide valuable insights into the high-level production of proteins in other Bacillus species.
