Background This study explored the utilization of luffa sponge (LS) in enhancing acetification processes. LS is known for having high porosity and specific surface area, can provide a novel means supporting growth acetic acid bacteria (AAB) to improve biomass yield rate, thereby promote more efficient sustainable vinegar production. Moreover, promising potential coated with κ-carrageenan (LSK) they may represent effective alternatives co-production industrially valuable bioproducts, example bacterial cellulose (BC) acid. Methods LSK were employed as adsorbents Acetobacter pasteurianus UMCC 2951 submerged semi-continuous process. Experiments conducted under reciprocal shaking at 1 Hz temperature 32 °C. The performance two systems (LS-AAB LSK-AAB respectively) was evaluated based on cell dry weight (CDW), BC biofilm formation. Results use significantly increased during acetification, achieving CDW 3.34 mg/L versus 0.91 obtained planktonic cells. Coating further enhanced yield, 4.45 mg/L.

By decoding the behavioral mechanisms underlying material perception, this study pioneers a sensory nudging strategy to accelerate adoption of sustainable materials. This study, grounded in Stimulus-Organism-Response (S-O-R) model, investigates factors influencing purchase intention and loyalty wood-plastic composites (WPCs), specifically examining impact stimuli, surface treatment processes, product carriers, environmental stimuli on consumers’ perceptions uniqueness emotional responses. A total 335 valid questionnaires were collected analyzed using Structural Equation Modelling (SEM), with results indicating that strongest predictors perceived Moreover, response had significantly stronger effect compared perception. Additionally, familiarity positively moderated relationship between intention. provides theoretical support for marketing WPCs, emphasizes significance integrating properties, treatments, usage environments design, suggests new avenues future research, particularly regarding multisensory experiences consumer behavior.
