Valorization of Brewery Wastes for the Synthesis of Silver Nanocomposites Containing Orthophosphate

Brewery wastes from stage 5 (Wort precipitate: BW5) and stage 7 (Brewer’s spent yeast: BW7) were valorized for the synthesis of silver phosphate nanocomposites. Nanoparticles were synthesized by converting silver salt in the presence of brewery wastes at different temperatures (25, 50, and 80 °C) an...

520			\|a Brewery wastes from stage 5 (Wort precipitate: BW5) and stage 7 (Brewer’s spent yeast: BW7) were valorized for the synthesis of silver phosphate nanocomposites. Nanoparticles were synthesized by converting silver salt in the presence of brewery wastes at different temperatures (25, 50, and 80 °C) and times (10, 30, and 120 min). Unexpectedly, BW7 yielded Ag<sub<3</sub<PO<sub<4</sub< nanoparticles with minor contents of AgCl and Ag metal (Ag<sub<met</sub<). Contrastingly, BW5 produced AgCl nanoparticles with minor amounts of Ag<sub<3</sub<PO<sub<4</sub< and Ag<sub<met</sub<. Nanocomposites with different component ratios were obtained by simply varying the synthesis temperature and time. The morphology of the nanocomposites contained ball-like structures representative of Ag<sub<3</sub<PO<sub<4</sub< and stacked layers and fused particles representing AgCl and Ag<sub<met</sub<. The capping on the nanoparticles contained organic groups from the brewery by-products, and the surface overlayer had a rich chemical composition. The organic overlayers on BW7 nanocomposites were thinner than those on BW5 nanocomposites. Notably, the nanocomposites exhibited high antibacterial activity against <i<Escherichia coli</i< ATCC 25922. The antibacterial activity was higher for BW7 nanocomposites due to a larger silver phosphate content in the composition and a thin organic overlayer. The growth of Ag<sub<met</sub< in the structure adversely affected the antimicrobial property of the nanocomposites.

Nanoparticles were synthesized by converting silver salt in the presence of brewery wastes at different temperatures (25, 50, and 80 °C) and times (10, 30, and 120 min). Unexpectedly, BW7 yielded Ag<sub<3</sub<PO<sub<4</sub< nanoparticles with minor contents of AgCl and Ag metal (Ag<sub<met</sub<). Contrastingly, BW5 produced AgCl nanoparticles with minor amounts of Ag<sub<3</sub<PO<sub<4</sub< and Ag<sub<met</sub<. Nanocomposites with different component ratios were obtained by simply varying the synthesis temperature and time. The morphology of the nanocomposites contained ball-like structures representative of Ag<sub<3</sub<PO<sub<4</sub< and stacked layers and fused particles representing AgCl and Ag<sub<met</sub<. The capping on the nanoparticles contained organic groups from the brewery by-products, and the surface overlayer had a rich chemical composition. The organic overlayers on BW7 nanocomposites were thinner than those on BW5 nanocomposites. Notably, the nanocomposites exhibited high antibacterial activity against <i<Escherichia coli</i< ATCC 25922. The antibacterial activity was higher for BW7 nanocomposites due to a larger silver phosphate content in the composition and a thin organic overlayer.

abstract	Brewery wastes from stage 5 (Wort precipitate: BW5) and stage 7 (Brewer’s spent yeast: BW7) were valorized for the synthesis of silver phosphate nanocomposites. Nanoparticles were synthesized by converting silver salt in the presence of brewery wastes at different temperatures (25, 50, and 80 °C) and times (10, 30, and 120 min). Unexpectedly, BW7 yielded Ag<sub<3</sub<PO<sub<4</sub< nanoparticles with minor contents of AgCl and Ag metal (Ag<sub<met</sub<). Contrastingly, BW5 produced AgCl nanoparticles with minor amounts of Ag<sub<3</sub<PO<sub<4</sub< and Ag<sub<met</sub<. Nanocomposites with different component ratios were obtained by simply varying the synthesis temperature and time. The morphology of the nanocomposites contained ball-like structures representative of Ag<sub<3</sub<PO<sub<4</sub< and stacked layers and fused particles representing AgCl and Ag<sub<met</sub<. The capping on the nanoparticles contained organic groups from the brewery by-products, and the surface overlayer had a rich chemical composition. The organic overlayers on BW7 nanocomposites were thinner than those on BW5 nanocomposites. Notably, the nanocomposites exhibited high antibacterial activity against <i<Escherichia coli</i< ATCC 25922. The antibacterial activity was higher for BW7 nanocomposites due to a larger silver phosphate content in the composition and a thin organic overlayer. The growth of Ag<sub<met</sub< in the structure adversely affected the antimicrobial property of the nanocomposites.
abstractGer	Brewery wastes from stage 5 (Wort precipitate: BW5) and stage 7 (Brewer’s spent yeast: BW7) were valorized for the synthesis of silver phosphate nanocomposites. Nanoparticles were synthesized by converting silver salt in the presence of brewery wastes at different temperatures (25, 50, and 80 °C) and times (10, 30, and 120 min). Unexpectedly, BW7 yielded Ag<sub<3</sub<PO<sub<4</sub< nanoparticles with minor contents of AgCl and Ag metal (Ag<sub<met</sub<). Contrastingly, BW5 produced AgCl nanoparticles with minor amounts of Ag<sub<3</sub<PO<sub<4</sub< and Ag<sub<met</sub<. Nanocomposites with different component ratios were obtained by simply varying the synthesis temperature and time. The morphology of the nanocomposites contained ball-like structures representative of Ag<sub<3</sub<PO<sub<4</sub< and stacked layers and fused particles representing AgCl and Ag<sub<met</sub<. The capping on the nanoparticles contained organic groups from the brewery by-products, and the surface overlayer had a rich chemical composition. The organic overlayers on BW7 nanocomposites were thinner than those on BW5 nanocomposites. Notably, the nanocomposites exhibited high antibacterial activity against <i<Escherichia coli</i< ATCC 25922. The antibacterial activity was higher for BW7 nanocomposites due to a larger silver phosphate content in the composition and a thin organic overlayer. The growth of Ag<sub<met</sub< in the structure adversely affected the antimicrobial property of the nanocomposites.
