Summary: Population growth and economic activities have led to environmental impacts, necessitating a shift towards sustainable and resource-efficient circular business models. This study proposes the use of waste as raw materials for the production of 1,3-propanediol, an important molecule used in polymer synthesis. The bacteria Clostridium butyricum NCIMB 8082 were able to grow and produce 1,3-propanediol using crude glycerol and corn steep liquor as the sole medium.

Summary: This study investigated the conversion pathways of major organic contaminants within the microbial electrolytic treatment of wastewater from food waste hydrothermal liquefaction. The findings demonstrated that volatile fatty acids and alcohols were effectively transformed through the synergistic metabolism of fermentative and electroactive bacteria, leading to high chemical oxygen demand removal and H2 production rate. The study also revealed the persistence of nitrogen-containing heteroaromatics in the treatment process. The integration of chemical profiles and bioanode community profiles provided insights for enhancing treatment efficiency and facilitating resource recovery.

Summary: This study explores the techno-economic feasibility of using glycerol to produce propanediols. Selective hydrogenolysis of glycerol can produce 1,2-propanediol, while microbial fermentation of glycerol can produce 1,3-propanediol with the co-production of 2,3-butanediol and ethanol. Process integration reduces utility demands, but utilities are still major operating costs. The production cost of 1,3-propanediol by batch fermentation is higher than that of 1,2-propanediol, while fed-batch fermentation of microbial 1,3-propanediol is economically viable.

Summary: This study improves the co-production of 3-hydroxypropionic acid (3-HP) and 1,3-propanediol (1,3-PDO) by metabolic engineering of Escherichia coli and process optimization. The co-biosynthetic pathways of 3-HP and 1,3-PDO were recruited and optimized in E. coli, coupled with cofactor regeneration systems to increase product synthesis. Pathway rebalancing and block of by-product formation improved the net titer of 3-HP and 1,3-PDO. Glycerol flux towards 3-HP and 1,3-PDO synthesis was maximized by removing metabolic repression and fine-tuning the glycerol oxidation pathway. The optimized fermentation process produced 140.50 g/L of 3-HP and 1,3-PDO, with a net yield of 0.85 mol/mol.

Summary: 1,3-propanediol (1,3-PDO) is a valuable chemical used in the polymer industry, but its production from petroleum products has environmental disadvantages. This study explores the biobased fermentation of 1,3-PDO from glycerol using recombinant strains of Clostridium beijerinckii. By introducing genes from other strains and optimizing growth conditions, significant increases in 1,3-PDO production were achieved. The use of a specific promoter further enhanced the yield.

Summary: By varying the mass ratio of the swelling agent and the template during the synthesis, a series of tungsten-doped Pt/W-MCFs catalysts were prepared, with Pt/W-1.5MCFs showing the highest 1,3-propanediol selectivity and activity. The synergy between Pt nanoparticles and single-sited tetrahedral (WO4)-O-V species at the metal-oxide interface is proposed to be responsible for the differences in catalytic performances among the Pt/W-MCFs catalysts.

Summary: Glycerol conversion to 1,3-propanediol is an economical and sustainable approach, but traditional catalytic reactions often result in the production of 1,2-propanediol. Currently, tungsten-containing bifunctional catalysts are considered as highly effective and atom-economical catalytic systems for selectively hydrogenolysis of glycerol to 1,3-propanediol.

Summary: This study investigated the changes in dissolved organic nitrogen and the transformation of proteins and amino acids during anaerobic digestion of sludge treated with different pretreatments. The results showed that cysteine is an important component responsible for methane production and is resistant to degradation. The study also found that the metabolism of cysteine and methionine is absent in all sludge samples. Cysteine contributes to methane generation and the degradation of organic acids through its effect on oxidation-reduction potential and biomass activity.

Summary: The study developed a new MFC system coupled with integrated fixed-film activated sludge (IFAS) to enhance treatment efficiency and energy production. Experimental results showed that the MFC-IFAS/MA system produced higher power density and nitrogen removal compared to other systems. The superior electrochemical behavior and nitrogen removal of MFC-IFAS/MA were attributed to the symbiosis between fixed-biofilm and microalgae assimilation. This study provided new insights into the application of MFC and the symbiotic relationship between microalgae and IFAS.
