Summary: This study provides new evidence of the successful use of metal oxide nanoparticles in the remediation of heavy metals. Zinc oxide nanoparticles (ZnO NP) and copper oxide nanoparticles (CuO NP) were found to alleviate cadmium (Cd) toxicity in Phaseolus vulgaris L. seedlings and plants. The physiological and metabolic parameters were monitored to elucidate the mechanism and process of Cd-induced phytotoxic effects on bean. The NP dose-dependent response of P. vulgaris seedlings and the differential response of growing plants in terms of length and biomass were observed. Both ZnO NP and CuO NP were able to reduce the hypergeneration of hydrogen peroxide (H2O2) and enhance ROS scavenging enzymatic capacity, while inhibiting the activity of ROS producing enzymes. The modulation of redox enzymes involved in cellular homeostasis and maintaining reduced status in cells was also observed. ZnO NP triggered more significant metabolic regulations allowing to mitigate the oxidative damage caused by Cd.

Summary: In this study, biodegradation of benzo(a)pyrene was conducted using two strains of Pseudomonas, i.e WDE11 and WD23, isolated from refinery effluent. The maximum tolerances for benzo(a)pyrene were 250 mg/L and 225 mg/L for Pseudomonas sp. WD23 and Pseudomonas sp. WDE11 respectively. The degradation rate constants ranged from 0.0468 to 0.0513/day at 50 mg/L and 0.006 to 0.007 L/mg·day at 100 mg/L. The major degradation metabolites were identified as dihydroxy-pyrene, naphthalene-1,2-dicarboxylic acid, salicylic acid, and oxalic acid. The catechol 2,3 dioxygenase enzyme exhibited significant activity during the benzo(a)pyrene metabolism.

Summary: The study investigates the use of natural pigments as sustainable substitutes for synthetic textile dyes. Fungal pigments have gained attention due to their therapeutic applications and easy production, but there is limited data on pigment production through solid-state fermentation and optimization. In this study, Talaromyces sp. was grown using milk whey, and the production of pigments in solid and liquid media was evaluated. Pineapple peels were utilized as a cost-effective substrate for pigment production, and a one-factor-at-a-time approach was employed to enhance pigment production. The resulting crude pigment showed promising antibacterial and significant antioxidant properties. Fabric dyeing experiments with different mordants were conducted to assess the possible use of the extracted fungal pigment as an eco-friendly textile dye. This work contributes to the valorization of agricultural waste and provides insights into utilizing fungal pigments as sustainable alternatives to synthetic textile dyes.

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.
