Summary: Ultrasonication assisted ionic liquid pretreatment was applied to enhance photo-fermentative biohydrogen production from Arundo donax L. biomass. The optimal conditions were found to be 16 g/L of 1-Butyl-3-methylimidazolium Hydrogen Sulfate ([Bmim]HSO4) combined with ultrasonication at a solid to liquid ratio (SLR) of 1:10 for 1.5 h under 60 °C. The maximum delignification achieved was 22.9%, and the hydrogen yield and energy conversion efficiency were increased by 1.5-fold and 46.4% (p < 0.05), respectively, compared to untreated biomass. Heat map analysis indicated that pretreatment temperature had the strongest correlation with hydrogen yield.

Summary: This study developed a choline chloride/1,4-butanediol deep eutectic solvent (DES) pretreatment aided with AlCl3/NaOH to dissociate the lignin macromolecular structure of corn straw and promote biohydrogen production. The alkali-catalyzed DES pretreatment achieved a higher yield of biohydrogen production compared to acid-catalyzed DES pretreatment. The enhanced biohydrogen production was attributed to the higher lignin removal rate of the alkali-catalyzed DES pretreatment, which facilitated enzymatic saccharification and dark fermentation of carbohydrate. The recovered lignin from this pretreatment exhibited well-preserved beta-O-4 ' linkages and regular spherical particles.

Summary: Photo nanocatalyst play a promising role in various fields, especially in biohydrogen production, where their catalytic efficiency depends on size, surface-to-volume ratio, and number of surface atoms. They can utilize solar light to generate electron-hole pairs, which is crucial for their catalytic efficiency and requires appropriate excitation wavelength, band energy, and crystal imperfections. This review discusses the role of photo nanocatalysts in catalyzing biohydrogen production. It highlights the large bandgap and high defect concentration of photo nanocatalysts, allowing customization of their characteristics. The mechanism of photo nanocatalysts in catalyzing biohydrogen production is explored, and limiting factors are addressed, along with recommendations to enhance the utilization of these photo nanocatalysts in photo-fermentative biohydrogen production from biomass wastes.

Summary: Deep eutectic solvent pretreatment was effective in increasing hydrogen yield via photo-fermentation in corncob by dissolving lignin, retaining cellulose, enhancing enzymatic hydrolysis, and shortening the delay period of hydrogen production. The maximum cumulative hydrogen yield obtained under the pretreatment condition of 50 degrees C and 12 h was 677.45 mL, which was 2.72 times higher than that of untreated corncob. The cellulose content in pretreated corncob positively correlated with reducing sugar concentration and hydrogen yield, and had the strongest influence on hydrogen production.

Summary: This study investigated the impact of the non-antibiotic pharmaceutical carbamazepine on antibiotic resistance genes (ARGs) during anaerobic digestion. The results showed that carbamazepine induced the enrichment of ARGs and increased the abundance of bacteria carrying these genes. It also facilitated microbial aggregation and intercellular communication, leading to an increased frequency of ARGs transmission. Moreover, carbamazepine promoted the acquisition of ARGs by pathogens and elevated their overall abundance.

Summary: This paper developed a machine learning model to predict the biochemical methane potential during anaerobic digestion. Model analysis identified lignin content, organic loading, and nitrogen content as key attributes for methane production prediction. For feedstocks with high cellulose content, early methane production is lower but can be improved by prolonging digestion time. Moreover, lignin content exceeding a certain value significantly inhibits methane production.
