Summary: The study proposes and demonstrates the use of sulfite pretreatment to efficiently produce medium chain fatty acids (MCFAs) through anaerobic fermentation of waste activated sludge (WAS). The pretreatment of WAS at a sulfite concentration of 100-500 mg S/L for 24 h significantly improves MCFAs production and selectivity, with the effect positively correlated with sulfite concentration. The findings suggest that sulfite pretreatment enhances MCFAs production and WAS degradation, while promoting solubilization, hydrolysis, and acidification processes.

Summary: A new strategy based on thiosulfate pretreatment was proposed to enhance short-chain fatty acids (SCFAs) production during anaerobic fermentation (AF) of waste activated sludge (WAS). The addition of thiosulfate significantly improved the disintegration of WAS, leading to increased SCFA yield. This was achieved through the binding of thiosulfate to organic-binding cations, dispersing the extracellular polymeric substance (EPS) structure and causing cell lysis. The enzyme activities and gene abundances showed enhanced hydrolysis and acidogenesis, while methanogenesis was suppressed. This cost-effective and efficient strategy provides a new approach for resource recovery through thiosulfate-assisted WAS AF.

Summary: This study explored the potential effects of the pollutant carbamazepine (CBZ) on anaerobic fermentation of waste activated sludge. The results showed that CBZ at environmental levels slightly promoted the production of short-chain fatty acids (SCFAs), but high doses of CBZ decreased the production of SCFAs. The abundance of certain functional traits changed during CBZ exposure, and the adverse effect was sustained due to CBZ being non-degradable during anaerobic fermentation. A regulation strategy using persulfate was proposed to mitigate the toxicity of CBZ, and it achieved a removal rate of 83.7%.

Summary: In recent years, the use of microalgae for the bioremediation of pharmaceuticals has gained attention. While most studies have focused on the removal performance of microalgae, their defensive response to pharmaceuticals during wastewater treatment has been overlooked. This study investigated the defensive systems of microalgae in synthetic wastewater and found that pharmaceuticals could bind to EPS, alleviating their direct toxicity to microalgae. Physiological analyses showed increased activity of antioxidant enzymes, suggesting a reduction in oxidative stress. Additionally, enzyme activities related to biotransformation and detoxification were upregulated, indicating the potential for the degradation and transformation of pharmaceuticals in microalgae.

Summary: Converting microalgal biomass into biochar is a popular approach for treating organic pollutants. This study investigates the relationship between adsorption efficiency and microalgal composition. The results show that microalgal biochar collected during the mid-log phase of growth exhibits the best adsorption capacity. This is attributed to the higher decomposition of microalgal cellular proteins and the presence of larger surface area, pore volume, and functional groups.

Summary: In this study, a comparative DFT calculation was conducted to understand the elementary surface reactions of CO hydrogenation reactions on Cu and ZnCu alloy surfaces. The results revealed that the reaction pathways and rate-limiting steps were different on ZnCu alloy and Cu surfaces. The key difference lies in the desorption of CH3OH* species on ZnCu alloy surface, which produces CH3OH, while on Cu surface, it undergoes H*-assisted decomposition to CH3* and eventually to CH4. These findings provide a comprehensive understanding of CO hydrogenation reactions on Cu and ZnCu alloy surfaces.

Summary: This study isolated and identified the coding genes of CsLCYB and CsLCYE in the lutein-enriched microalga Chlorella sorokiniana FZU60. Bioinformatics analysis revealed the key structural domains of CsLCYB and CsLCYE. CsLCYB efficiently beta-cyclized lycopene to produce beta-carotene, while CsLCYE exhibited strong epsilon-monocyclase activity for delta-carotene production and weak -bicyclic activity for -carotene production. Co-expression of CsLCYB and CsLCYE resulted in the major production of alpha-carotene, suggesting the potential for high-level lutein production in C. sorokiniana FZU60.
