Bioconversion of coffee waste via two-stage fermentation using Saccharomyces cerevisiae and Escherichia coli

In this study, a two-stage fermentation strategy using Saccharomyces cerevisiae and Escherichia coli was developed for spent coffee grounds (SCG) hydrolysate valorization. In the first stage, S. cerevisiae ATCC 13,007 was cultivated in thermally and acid-hydrolyzed SCG hydrolysat...

Structural Evolution of RAFT-Modified Unsaturated Polyester Copolymers: Effects of CPDT Concentration, Acidic Comonomer Structure, and Polyester Matrix Architecture

Unsaturated polyester resins (UPRs) represent challenging systems for reversible-deactivation radical polymerization (RDRP) because chain propagation, branching, and localized gelation may occur concurrently. This study systematically investigates the influence of the concentrati...
