Summary: Cadmium is a dreadful heavy metal, which is becoming a major toxicant in ground water with concentration exceeding the WHO Guidelines in drinking water. The potential sources of cadmium include sewage sludge, phosphate fertilizers, and various ingredients. The authors evaluated the growth and Cd(II) remediation capacity of a Cd(II) resistant yeast strain named Candida tropicalis XTA 1874. By analyzing the optimization conditions, a synthetic medium was developed which significantly enhanced the strain's Cd(II) adsorption capacity.

Summary: This study designed Eucalyptus Bark (EB) and its composites as adsorbents to eliminate Basic Blue 41 (BB41) dye from polluted water bodies. The as-prepared adsorbents exhibited high adsorption capacity and decolorization efficiency due to the existence of negatively charged functional groups on the adsorbent surface. Isothermal and kinetic studies revealed that the adsorption data fitted well with Freundlich and pseudo 2nd order models. The thermodynamic examination confirmed that the adsorption process is spontaneous, chemisorption, and exothermic. This study highlights the potential of magnetic and polypyrrole composites with EB biomass as eco-friendly adsorbents for wastewater remediation.

Summary: Two extremophilic biosorbents were used to successfully remove Cu(II), Ni(II), and Pb(II) from aqueous solutions. The biosorbents showed high affinity for these metal ions, with removal rates ranging from 73.6% to 100%, and the removal order was Pb(II) > Cu(II) > Ni(II). Both Langmuir and Freundlich models were suitable for describing the adsorption process, with the pseudo-second-order reaction model being more accurate than the pseudo-first-order model kinetically.

Summary: The study focuses on investigating the effect of Ni2+ on neuronal autofluorescence, and utilizes a bioinorganic nanostructured hybrid material with heavy metal removal potential: yeast Saccharomyces cerevisiae modified with Silsesquioxane for adsorption experiments. The results show that in the presence of a certain concentration of Ni2+, irreversible autofluorescence changes occur. The hybrid material exhibits a maximum sorption capacity of 64.6 mg/g, with a removal rate of 77.7% for the initial Ni2+ solution under specific conditions.

Summary: It was found that the surface properties of green alga Neochloris oleoabundans varied with different culture pH conditions, and biomass obtained at pH 9.5 exhibited the highest heavy metal ion (HMI) biosorption capacity. Further analysis revealed that the higher content of carboxyl (COOH) group on the B-9.5 cell surface might be responsible for its high HMI biosorption capacity.

Summary: Researchers engineered baker's yeast to produce retinal and used it for screening of ChR2 protein function. They found that light activation of ChR2 increased sodium influx and inhibited cell growth, and in a potassium uptake-deficient yeast strain, growth could be rescued by the blue light-induced K+ conductance of ChR2. This study provides a simple and convenient method for screening new functional ChR2 variants.

Summary: The study demonstrated that Caryocar Coriaceum Wittm bark can serve as a potential bioadsorbent for the effective removal of copper (II) from aqueous solutions. Increasing temperatures favor the adsorption capacity of copper (II), and the bioadsorption process is characterized by chemisorption with intra-film diffusion. Langmuir's model best represents the biosorption process.

Summary: The thermal adsorption residue (TDR) derived from oil sludge co-contaminated soil was found to effectively neutralize acid substances and adapt to a wide pH range. It demonstrated high adsorption capacities for four heavy metals, namely As(III), Zn(II), Cu(II), and Cd(II). There was a competitive adsorption among the three cations on TDR, and the presence of As(III) lowered the adsorption capacity of Zn(II), Cu(II), and Cd(II).

Summary: This study focuses on the application and evaluation of diatomite as an adsorbent for Nd3+, Ce3+, and La3+ rare earth elements (REEs). The results show that diatomite has a porous and cylindrical structure with a specific surface area of 150 m2/g. The diatomite can effectively adsorb cationic REEs, with the uptake percentage increasing in the order of La3+, Ce3+, and Nd3+. Kinetic and equilibrium processes were best described by the Avrami-fractional order (AFO) and Liu isotherm model, respectively. The research demonstrates that diatomite is a sustainable and low-cost adsorbent for REEs recovery from synthetic and real effluents.

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.
