Summary: The study focused on converting industrial waste, specifically cellulosic fiber waste, into bioethanol as an alternative energy source. Various treatments, including physical, chemical, and enzymatic hydrolysis, were used to maximize glucose concentration for fermentation into bioethanol. The results showed that the combination of treatments led to a glucose production of 13.9 mg/mL, while instrumental characterization confirmed the effectiveness of the waste fiber treatment. A yeast strain, Starmerella bacillaris STDF-G4, was identified and used to ferment glucose into bioethanol under optimized conditions, resulting in a production of 3.16 mg/mL. Scaling up the optimized conditions in a fermentation bioreactor further increased bioethanol production to 8.6 mg/mL.

Summary: The aim of this study was to investigate the use of Chlorella sorokiniana SU-1 biomass grown on dairy wastewater-amended medium as a sustainable feedstock for the biosynthesis of 0-carotene and polyhydroxybutyrate (PHB) by Rhodotorula glutinis #100-29. Rigid cell walls of the microalgal biomass were broken down using 3% sulfuric acid and detoxified with 5% activated carbon. Fermentation using the detoxified microalgal hydrolysate (DMH) resulted in maximum biomass production of 9.22 g/L, with concentrations of PHB and 0-carotene reaching 897 mg/L and 93.62 mg/L, respectively. Upscaling to a 5-L fermenter increased biomass concentration to 11.2 g/L, with PHB and 0-carotene concentrations of 1830 mg/L and 134.2 mg/L.

Summary: The study assessed the risks of two mobilising agents, Na2S2O4-EDTA and C6H8O7, in remediating As-contaminated soils. Both agents increased ecological risk but had opposite effects on health risk. Na2S2O4-EDTA increased As relative bioavailability and bioaccessibility while C6H8O7 reduced them and promoted As(III) methylation. This study provides important insights for mobilising agent selection and managing remediation sites.

Summary: Developing effective marine water quality criteria (WQC) is important for controlling marine contamination and protecting marine life. This study derived short-term water quality criteria (SWQC) and long-term water quality criteria (LWQC) for copper in Bohai Bay using the species sensitivity distribution (SSD10) method. The derived WQC values were obtained directly from the hazardous concentration for 5% of species (HC5), eliminating the influence of arbitrary assessment factor (AF). Additionally, modifications to the acute-chronic ratio (ACR) strategies and the inclusion of local species' toxicity data improved the accuracy and applicability of the WQC values. The overall risk level of copper in Bohai Bay was evaluated to be at a moderate-low level using the risk quotient (RQ) method. This study provides a new approach for deriving WQC for copper and assessing the risk in Bohai Bay, which is crucial for protecting local aquatic life and guiding the establishment of national WQC.

Summary: This study investigated the abundance, diversity, and community structure of heterotrophic protists known as Labyrinthulomycetes protists (LP) in the coastal zone of Hainan Island in the South China Sea. The results showed variations in LP abundance by location and depth, with the highest levels found in the middle layer offshore and the lowest in the bottom layer offshore. The LP community was dominated by the genus Aplanochytrium, and four different ecotypes were identified. These findings contribute to our understanding of LP in coastal ecosystems and raise questions about their potential ecological differentiation.

Summary: Understanding photochromism is crucial for developing new ways to modulate the optical responses of materials. In this study, ammonium tungsten bronze (NH4)xWO3 with a unique flower-like hierarchical structure was prepared, leading to a significant advance in photochromism. The large surface area exposed more photoactive sites, resulting in a high color difference. The study also revealed the essential surface structure-breaking behaviors of hydrogen bonds between NH4+ and tunneled WO3 frameworks. Furthermore, the energy-saving window based on hydrogen ammonium tungsten bronze coating showed great potential for reducing indoor air temperature and temperature difference between various indoor areas.
