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: Avicel cellulose was pretreated with two commonly used carboxylic acid-based deep eutectic solvents, choline chloride-lactic acid and choline chloride-formic acid. The pretreatment led to the formation of cellulose esters with lactic acid and formic acid, which was confirmed through spectroscopic analysis. Surprisingly, the esterified cellulose showed a significant decrease in enzymatic glucose yield compared to the untreated cellulose, but this reduction could be recovered by removing the ester groups through saponification. The decreased enzymatic cellulose hydrolysis may be attributed to changes in the interaction between the cellulose-binding domain of cellulase and the esterified cellulose.

Summary: This study investigates the cellulose crystalline structure differences between bamboo fibers and parenchyma cells and their effects on ionic liquid pretreatment and sugar conversion yield. The results show that cellulose from bamboo fibers exhibits higher resistance to pretreatment, with minimal changes in crystallinity, crystallite sizes, and easier transformation to cellulose II. In contrast, cellulose from parenchyma cells behaves differently. Furthermore, the (110) and (11??0) lattice planes exhibit more changes in crystalline parameters compared to the (200) direction.

Summary: Deconstruction of cell wall structure is important for biorefining of lignocellulose to produce biofuels and chemicals. This review article discusses various oxidative pretreatment methods including wet oxidation, alkaline hydrogen peroxide, organic peracids, Fenton oxidation, and ozone oxidation. The primary mechanism of oxidative pretreatment is delignification, particularly in alkaline medium, which improves cellulose digestibility by eliminating the physical blocking and non-productive adsorption of enzymes by lignin. However, the cost of oxidative delignification is currently too expensive for large-scale applications.

Summary: SCPR140-1, a stable solid acid catalyst synthesized from chloromethyl polystyrene resin, showed high selectivity for xylose production and effectively deconstructed the structure of corncob during catalytic pretreatment. Compared to other similar reports, SCPR140-1 was not only synthesized through a simpler process but also demonstrated more stable catalytic activity during multiple recycling runs.

Summary: The combination of waste distillery stillage and sugar-rich beet molasses for ethanol production showed promising results in increasing ethanol concentration and yield. However, attempts to use cellulases for hydrolysis to increase fermentable sugars were unsuccessful, leading to increased concentrations of ethyl acetate and other volatile by-products in the fermentation media. Further optimization of the cellulose enzymatic hydrolysis process is needed for efficient use of the raw material.

Summary: In this study, the microbial inactivation efficacy of custom-made FE-DBD plasma at different frequencies on a glass surface was experimentally evaluated. Results showed significant microbial reduction at all frequencies tested. Numerical predictions closely matched experimental data, with a slight difference likely due to complex interactions between plasma species.

Summary: Plasma-activated water (PAW) is an emerging disinfectant with high antimicrobial activity thanks to various reactive oxygen and nitrogen species. It showed higher effectiveness against E. coli than L. innocua, with acidic pH and nitrogen species contributing synergistically to its inactivation efficacy. Fresh PAW demonstrated the highest inactivation efficacy, while refrigerated PAW maintained inactivation efficacy better than PAW stored at room temperature due to delayed dissipation of reactive species.

Summary: This study investigated a novel nonthermal sanitization technique, cold plasma-activated water (PAW), for washing shell eggs. Washing inoculated eggs with PAW achieved a similar microbial reduction as quaternary ammonia (QA) and did not adversely affect the shell structure or cuticle coverage. According to the results, PAW has the potential to be an alternative to commercial sanitizers like QA in the egg-washing industry.
