Summary: Environmental concerns regarding industrial wastewater containing dyes have increased with industrial development. Decolorization of industrial effluents is crucial for color-free discharge. Biodegradation using laccase enzyme has emerged as a competitive method. Laccase, a green catalyst, exhibits high catalytic activity and has been extensively studied for dye remediation, but immobilization is necessary to fully utilize its potential.

Summary: This study isolated a novel halotolerant phenol-degrading yeast strain, SDP-1, from a coastal soil in Jiangsu, China, and identified it as Candida tropicalis based on morphology and genetic sequence analysis. SDP-1 efficiently removes phenol under a wide range of conditions, utilizes various phenol derivatives as carbon sources, and shows high tolerance to salts. Immobilized SDP-1 exhibits enhanced phenol degradation efficiency compared to free cells, making it a potential candidate for phenol-contaminated wastewater and soil treatment in hypersaline environments.

Summary: In the process of urbanization, anthropogenic activities, industrialization, and economic growth have led to waste management problems, disposal issues, and the emergence of pollutants. To maintain a sustainable environment, bioremediation using microorganisms or enzymes is a promising solution. Laccase, an oxidoreductase enzyme produced by microorganisms, has shown great potential in degrading chemical pollutants. However, challenges such as immobilization and engineering of robust laccase need to be addressed for large-scale application in waste treatment and emerging pollutant degradation.

Summary: Due to its simple process, environmental friendliness, and low operating costs, biometallurgy has become a popular technology for metals recovering from low-grade ores and tailings. An optimized agar was used to isolate and grow functional bacteria, resulting in the successful isolation of six functional stains. These strains were further tested for their ability to leach metals from polymetallic sulfide tailings, with significant improvements observed when the strains were mixed together. The selection of leaching process should be based on tailings composition and target metals.

Summary: This study examines the association between urban Green and blue spaces (GBS) exposure and Emotion and behavior problems (EBP) in youth populations. The findings suggest that higher exposure to GBS, particularly green spaces (GS) and blue spaces (BS), is associated with a decrease in the risk of developing total difficulties in young individuals. The joint effect of GS and BS may also contribute to the decrease in EBPs.

Summary: The present study investigated the sustainable approach for wastewater treatment using waste algal blooms. The biochar produced by the marine algae Ulva reticulata was used to remove chromium, nickel, and zinc from aqueous solutions. The study examined the adsorbents' properties and stability using SEM/EDX, FTIR, and XRD. The results showed that the biochar had high removal efficiency for the toxic metals, and the packed bed column effectively removed the heavy metal ions. The Thomas and Adams-Bohart models were found to best fit the regression values, and desorption studies were conducted to understand the sorption and elution processes.

Summary: The selection of predictor variables is crucial in building a digital mapping model for potentially toxic elements (PTEs) in soil. Traditionally, spatial and spectral parameters have been used as predictor variables, but the temporal dimension is often overlooked. This study demonstrates the value of incorporating temporal indices in the model, leading to significant performance improvements. The temporal-spatial-spectral covariate combinations used in a random forest (RF) algorithm achieve satisfactory mapping accuracy and outperform other methods.
