Mn and Fe BPMEN complexes showed excellent reactivity in catalytic oxidation with an excess of co-reagent (CHCOOH). In the straight line of a cleaner catalytic system, volatile acetic acid was replaced by (nano)particles with two different sizes to which pending carboxylic functions were added (). The beads were obtained by the functionalization of SiO with pending nitrile functions () followed by CN hydrolysis. All complexes and silica beads were characterized by NMR, infrared, DLS, TEM, X-ray diffraction. The replacement of CHCOOH by (100 times less on molar ratio) has been evaluated for (ep)oxidation on several substrates (cyclooctene, cyclohexene, cyclohexanol) and discussed in terms of activity and green metrics.

Genes in microorganisms influence the biological processes in anaerobic digestion (AD). However, key genes involved in the four metabolic steps (hydrolysis, acidogenesis, acetogenesis, and methanogenesis) remain largely unexplored. This study investigated the abundance and distribution of key functional genes in full-scale anaerobic digesters processing food waste (FWDs) and municipal wastewater (MWDs) through 16S rRNA gene and shotgun metagenomic analysis.

Volatile fatty acids (VFAs) are suitable substrates for synthesizing poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV), wherein propionate is a precursor of PHBV biosynthesis; however, high concentrations are toxic to bacteria. Therefore, VFAs with suitable ratio are needed. Here, with the ratio of acetate: propionate: butyrate being 1:4:2, the maximum PHBV content and the 3HV content were 46.

The purpose of this study was to evaluate the impact of different additives in fermented indigo waste on feed availability, rumen fermentation patterns, blood chemistry, and hematology in beef cattle. Four male crossbred beef cattle with a body weight (BW) of 230 ± 14 kg and 25 months of age were used in a 4 × 4 Latin square design. The indigo waste was ensiled without additive (CON) and with calcium hydroxide (CH), molasses (M), or cellulase (C).

Chlorinated and oxygenated volatile organic compounds (CVOCs and OVOCs) pose a significant threat to human health. Catalytic oxidation effectively removes these pollutants, but catalyst deactivation is a challenge. Our study focused on the hydrolysis oxidation of chlorobenzene (CB) and ethyl acetate (EA) over Ru/MO/HZSM-5 (M = W, Mo).
