Methanogenic biotransformation of unusual substrates (sulfur (S)-containing wastes: non-purified vacuum gas oil, straight-run gasoline fraction (Naphtha), gas condensate, and straight-run diesel fraction) coming from oil industry after their oxidative desulfurization was investigated. Nitrogen-containing wastes (hydrolysates of chicken manure and Chlorella vulgaris biomass) were added as co-substrates to mixture with oil industry wastes. The 100 % conversion of S-organic compounds to inorganic sulfide accumulated in the reaction liquid medium was achieved with simultaneous production of biogas containing high methane percent (greater than 70 %). Polishing of effluents from methane tank was carried out by denitrifying oxidation of ammonium (DEAMOX). The high process efficiency was due to use of original immobilized artificial consortia at the stage of methanogenesis and DEAMOX. This study reveals the real potential in the processing of very complex mixtures of large-scale wastes, usually inhibiting methanogenesis, by developing biocatalysts based on synthetic biology approaches.

Degradable and cost-effective cellulose fiber-based materials are ideal substitutes for traditional plastics. However, organic additives used to enhance water and oil resistance often contain toxic substances that may migrate into food, posing health risks. In this study, inspired by tree structures, lignin-containing cellulose nanofibers (LCNFs) are used to form a "crown-roots" structure to enhance the water, oil, and gas resistance, as well as mechanical performance of composites.

Regulating favorable assemblies of metallic atoms in the liquid state provides promise for catalyzing various chemical reactions. Expanding the selection of metallic solvents, especially those with unique properties and low cost, enables access to distinctive fluidic atomic structures on the surface of liquid alloys and offers economic feasibility. Here, Sn solvent, as a low-cost commodity, supports unique atomic assemblies at the interface of molten SnInCu, which are highly selective for H synthesis from hydrocarbons.

In this study, the influence of tannic acid (TA)/soluble potato starch (PS) mass ratio and PS concentration on TA/PS complexes and emulsions stabilized by TA/PS complexes were studied. The size, hydrophobicity and emulsifying properties of TA/PS complexes were all controlled by TA/PS mass ratio and PS concentration. In detail, the hydrophobicity of PS (θ = 48°) improved after complexing with TA to form TA/PS complexes (θ = 64°).
