Summary: The utilization of sludge mixed liquor in microbial fuel cell and membrane bioreactor (MFC-MBR) coupling system was investigated. The effects of return flow on bioelectricity generation and membrane fouling were studied by designing MFC-MBR coupling systems with different return flow ratios. The results showed that bioelectricity generation was enhanced with the increasing return flow ratio. Additionally, MFC-MBR coupling systems with higher return flow ratios exhibited slower growth of transmembrane pressure and declined absolute value of zeta potential, indicating improved floc-culation of sludge particles and reduced soluble microbial products (SMP) and extracellular polymeric substances (EPS). Bacteroidetes and Chlorobiaceae were found to be more abundant in MFC-MBR coupling systems with higher return flow ratios.

Summary: The biosorption of Cd2+ ions from aqueous solutions by immobilized Turbinaria ornata biomasses was studied, and it was found to have a higher removal efficiency compared to free cells. The immobilized cells showed a maximum biosorption capacity for Cd2+ ions and followed pseudo-second-order and Elovich kinetic models. Additionally, the biosorption process is controlled by film diffusion followed by intra-particle diffusion. SEM/EDX and FTIR analyses confirmed the binding of Cd2+ ions onto the algal surface and the involvement of various functional groups in the biosorption process.

Summary: The aim of this study was to evaluate the efficiency of Spirulina platensis in removing Zn2+ ions from aqueous solutions. The results showed that under optimized conditions, up to 97.90% of Zn2+ was successfully removed by S. platensis, indicating a good agreement between experimental data and model predictions. The biosorption process of Zn2+ was found to be well characterized by the pseudo-second-order kinetic model, suggesting a chemical nature of the adsorption process. The Langmuir and Dubinin-Radushkevich isotherm models were found to best fit the equilibrium data, with a maximum adsorption capacity of 50.7 mg/g. Thermodynamic analysis revealed that the biosorption of Zn2+ was endothermic, spontaneous, and feasible. Additionally, FTIR, SEM, and EDX investigations showed noticeable changes in the properties of the algal biomass during the biosorption process. Therefore, dried Spirulina biomass has been proven to be a cost-effective and efficient method for removing heavy metals, particularly zinc ions, from wastewater, making it a feasible and environmentally acceptable approach.

The study also revealed the outstanding structural characteristics and high surface functional group availability of the biosorbent. Rose damascena leaves showed a higher adsorption capacity compared to immobilized ones. The main mechanism of interaction between the biosorbent and copper ions was determined to be both ion exchange and hydrogen bond formation.

Summary: The present study evaluates the photocatalytic degradation performance of biofabricated α-HNPs for the degradation of Cfm. The optimal pH for achieving the best degradation was found to be 10.5. The kinetics study revealed that the degradation reaction followed pseudo-first-order kinetics with a correlation coefficient of 0.992. The mass loading of α-HNPs was found to impact the degradation efficiency, with the maximum degradation observed at a concentration of 0.4 mg/mL. UV-Vis analysis confirmed the optical properties of α-HNPs, including a direct transition bandgap at 3.78 eV and suspension stability for 7 days. XRD, TEM, SEM, EDX, and FT-IR analyses confirmed the reusability and structural integrity of α-HNPs after Cfm degradation. The antibacterial and antiproliferative activities of α-HNPs were also investigated.

Summary: In this study, the response surface methodology-based Box-Behnken design was used to optimize the dry biomass, lipid content, and lipid yield of the new oleaginous fungus Aspergillus carneus OQ275240. The concentrations of yeast, glucose, and phosphorus were found to have mutual impacts on the fungus growth and lipid synthesis. At the optimal concentrations, the dry biomass, lipid content, and lipid yield reached 0.024 g/50 mL, 36.20%, and 8.70 mg/50 mL, respectively. The fatty acid methyl esters (FAMEs) profile of the fungus showed the presence of palmitic acid (C16:0), stearic acid (C18:0), and oleic acid (C18:1), which are ideal for biodiesel production. The biodiesel produced from this fungus met the international specifications EN 14214 and ASTM D6751-08. These findings suggest the potential of this newly evaluated filamentous fungal strain as a high-quality biodiesel feedstock.
