Summary: This study investigated the production of decaffeinated Qingzhuan tea (QZT) by inoculating Penicillium simplicissimum 4-17 into sun-dried green tea for pile fermentation. The results showed that after 21-day fermentation, most quality components in the decaffeinated tea were similar to those in naturally fermented QZT, except for caffeine. The addition of P. simplicissimum 4-17 contributed to high caffeine degradation ability and improved the overall quality of QZT.

Summary: This study presents a smart technological framework using bioremediation techniques to efficiently remove azithromycin from natural soil resources. The framework consists of multiple modules with different models, including bioactivity, soft computing, statistical optimization, machine learning algorithms, and a decision tree control system. The study used experiments and ML algorithms to predict the removal percentage of azithromycin based on cultural parameters, and found that pH and aeration intensity were the most significant factors. The optimal biological conditions for azithromycin removal were determined as a temperature of 32°C, pH of 5.5, M/F ratio of 1.59 mg/g, and AI of 8.59 m3/h. The IBK model provided the most accurate prediction of retention time.

Summary: Inspired by the biocompatibility and dexterity of ionic liquids in preserving enzyme structure and activity, this study investigated the interactions between Cyt-c and naked AuNPs as well as four IL-mediated AuNPs. The results showed that IL-AuNPs significantly enhanced the peroxidase activity and exhibited preference in counteracting temperature gradient change and long-term solvent preservation effects. The study also revealed the dominance of IL anions in modulating the interactions between IL-mediated AuNPs and Cyt-c. These findings suggest the promising potential of sulfur-containing IL-mediated AuNPs for Cyt-c immobilization and for applications in drug delivery and therapeutics.

Summary: In this study, a nano-bimetallic platinum/nickel composite on multi-walled carbon nanotubes (nano-Pt/Ni@MWCNT) was prepared as electrode material. The nano-Pt/Ni particles were anchored on the surface of the MWCNT, providing a large specific surface area and enhanced electrical conductivity. A flow-injection amperometric system using nano-Pt/Ni@MWCNT/GCE was utilized for electrochemical determination of promethazine (PMZ), with excellent reproducibility and interference tolerance. The viability of the nano-Pt/Ni@MWCNT/GCE was demonstrated for PMZ detection in spiked saliva, urine, and beverage samples, with high recoveries.

Summary: In this study, a phosphorus-boron co-doped hollow tubular g-C3N4 (xB-PCN) with an intra-molecular Donor-Acceptor like p-n isotype heterojunction was synthesized for high-efficiency visible light photocatalytic degradation of ciprofloxacin (CIP) in water. The xB-PCN exhibited excellent charge generation, separation, and transfer ability, resulting in a decomposition efficiency of 87.56% within 1 hour, with an apparent rate constant 6.85 times higher than that of conventional g-C3N4 (PCN). Furthermore, xB-PCN maintained high degradation percentages in tap water (84.63%) and aquaculture wastewater (78.41%). The degradation pathways of CIP were proposed, and the reactive oxygen species involved in the degradation process were identified through radical trapping experiments and ESR characterization.

Summary: In this study, a novel strategy was proposed to reduce the input of hydrogen peroxide (H2O2) in the Fenton process. The designed Cu catalyst (G-Cu) with two functional regions (Cu0 and OVs) was able to produce H2O2 in situ and promote its activation over the catalyst surface. This strategy resulted in higher degradation efficiency of oxytetracycline (OTC) with a smaller dosage of H2O2.

Summary: Excessive use of tetracycline in livestock farming has caused serious pollution. A new method proposed the catalytic thermal degradation of tetracycline using iron-based metal-organic frameworks (MOFs) and studied the mechanism. The annealing derivatives of three Fe-based MOFs showed better degradation performance than the raw materials due to the exposure of Fe-O clusters and the formation of oxygen vacancies. The optimum sample exhibited a degradation efficiency of 94.22% for tetracycline within 60 minutes at 70 degrees C.

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.
