Bacterial cellulose membranes find extensive applications in industries involving water purification, wastewater treatment, and biomedical uses. Nevertheless, prevailing membranes suffer from drawbacks like water flow hindrances and fouling susceptibility. Hence, the pressing need for more efficient and robust BC membranes. This study aims to assess the impact of a hybrid treatment involving Copper Oxide nanoparticles (CuO-NPs) and Graphene Oxide (GO) on bacterial nanocellulose membranes. The research employed two treatments: (1) control (BNCA), and (2) Bacterial cellulose infused with 0.5 wt% CuO-NPs/GO. The nanocellulose production involved a high-pressure homogenizer, followed by acetate nanocellulose synthesis and nanocomposite membrane functionalization with CuO nanoparticles. SEM, FTIR, and XRD analyses characterized the membranes. Successfully formed seaweed-derived bacterial cellulose had a thickness of 1-3 cm. Characterization showed it belonged to Cellulose type I with a crystalline degree ranging from 82.3% to 83.1%. FTIR analysis of dry BNCA membranes indicated changes in transmittance at 1738, 1554, and 764 cm-1 due to CuO-NPs/GO addition, altering the O-H bond in bacterial cellulose. Based on the results of the above research, it is evident that the Membrane Reinforced with CuO-NPs/Graphene Oxide has been successfully developed and holds potential as a water nanofiltration system.

“…This means that the tensile strength of BNC membrane differs signi cantly from the strength observed in nanocomposites containing 5.0wt.% and 7.5wt.% of ZnO-NPs. The chemical interaction between ZnO-NPs and BNC takes place through the OH groups of cellulose, leading to the formation of a secondary interaction involving hydrogen between the oxygen of ZnO-NPs and the hydroxyl group on the cellulose [21]. However, when the ZnO-NPs content is high, it causes signi cant agglomeration, resulting in more damage to membrane, as depicted in Fig.…”

Bacterial cellulose (BC) is a natural substance produced by microorganisms and offers numerous bene ts. It can be produced by utilizing biomass waste which is abundantly available through the fermentation process. This study investigates the utilization of pineapple peel waste for bacterial cellulose synthesis and observes their properties as nanocomposites membrane after the addition of ZnO nanoparticles (ZnO-NPs). The experimental methods were conducted by synthesizing BC using pineapple peel extract using fermentation process. Subsequently, BNC was synthesized using a high-pressure homogenizer, and ZnO-NPs nanoparticles were added as reinforcement at concentrations of 2.5 wt.%, 5.0 wt.%, and 7.5wt.%. The mixture was sonicated and subsequently dried in an oven at 60°C for 20 h. BNC/ZnO-NPs membranes were characterized using XRD, FTIR, tensile test, BET, antibacterial test, and SEM analysis. The results indicate that the membrane structure of BNC/ZnO-NPs nanocomposite has peaks at diffraction angles of 14.4°, 15.2°, 16.9°, 22.8°, 31.6°, 34.1°, and 36.8°. The addition of ZnO-NPs affects the crystallite size and pore diameter of the membrane. It enhances the crystalline index of BNC by 81.37% at 2.5wt.% ZnO-NPs but reduces the membrane strength. The surface morphology of nanocomposite shows agglomeration with increasing ZnO-NPs content. Membrane BNC/ZnO-NPs show antibacterial activity against S.aureus.
