Summary: A putative laccase from Sulfitobacter indolifex was found to be stable and active at low to ambient temperature and across a range of pH conditions, efficiently decolourising industrial dyes. Enzyme immobilisation technology significantly improved the tolerance of the laccase towards extreme pH and organic solvents. This study expands the arsenal of bacterial laccases available for dye-containing wastewater bioremediation.

Summary: Polypropylene and polystyrene were processed with a Ni-Fe/Al2O3 catalyst to produce carbon nanotubes (CNTs) in a pyrolysis/catalytic reactor. The MWCNTs produced had different structures and properties depending on the source of the plastic. Commercially produced MWCNTs showed higher degree of graphitisation and fewer defects compared to plastic derived MWCNTs.

Summary: In recent years, enzyme-based biocatalytic systems have gained increasing attention in industrial and applied research. These systems have been applied in sustainable and environmentally friendly production processes in various industries. However, the low stability of enzymes and difficulties in separation, recovery, and reusability have limited their industrial-scale manufacturing. Immobilization and co-immobilization on robust support materials have emerged as valuable strategies to overcome these challenges. By using environmentally friendly bio-polymers and nanostructured materials, multi-enzyme co-immobilization offers improved process efficiency and cost-effectiveness in biotechnological and chemical industries.

Summary: The study demonstrated that the application of MCNT increased soil enzyme activities that promote plant growth, but resulted in reductions in available nitrogen and potassium contents. Although the taxonomic compositions of soil microbes were altered by MCNT, the diversity of bacterial and fungal communities did not significantly change. The study also revealed a correlation between microbial community structure and soil organic carbon content, indicating the strong resistance and adaptation ability of soil microbes to carbon nanotubes in the presence of plants.

Summary: In this study, amino functionalized magnetic multi-walled carbon nanotubes (MMWCNT-NH2) were prepared via a facile one-pot solvothermal method, and their sorptive removal efficiency of the anionic dye Congo red (CR) from water was investigated. The composite with triethylenetetramine showed higher removal efficiency due to its higher content of amino groups. Characterization analyses confirmed its excellent magnetic separation property and successful introduction of amino groups on MMWCNTs. The adsorption process followed the pseudo-second-order kinetic model and a three-stage diffusion mechanism was observed. The adsorption performance of MMWCNT-NH2-3 showed significant improvement after amino functionalization, with a maximum adsorption capacity of 322.7 mg/g. Selective adsorption of anionic dye was achieved due to electrostatic attraction and electron donor-acceptor interaction. The prepared MMWCNT-NH2-3 exhibited excellent reusability performance and could be a promising adsorbent for the removal of anionic dye from wastewater.

Summary: In this study, the effects of multi-walled carbon nanotubes (MWCNTs) on plant development, oxidative stress, and heavy metal behavior in a corn-soil system were assessed. The results showed that the application of 100 and 500 mg kg 1 MWCNTs improved shoot length and total plant dry biomass, while 1000 mg kg 1 MWCNTs decreased total plant dry biomass. MWCNTs did not affect Cd accumulation in plants but reduced the bio-concentration factor of As. Exposure to MWCNTs increased oxidative stress in corn plants, but also decreased the levels of extractable Cd and As in soil. This study suggests the potential application of MWCNTs in agricultural production for mitigating the toxicity of heavy metals and ensuring soil sustainability.

Summary: Chemical etching of carbon cloths (CCs) with potassium hydroxide (KOH) has been used to enhance their specific surface area (SSA). Different weight ratios (WRs) of CCs to KOH were investigated to understand pore development mechanism. The activated CCs with a WR of 0.01 wt%/wt% showed more than 15-fold increase in SSA compared to neat CCs, primarily due to outside-in pore deepening and metallic potassium intercalation. The introduction of KOH also affected defective sites and surface energy.
