Effect of Sugar Concentrations on Bacterial Cellulose Production as Cellulose Membrane in Mixture Liquid Medium and Material Properties Analysis
Year: 2013
Type: conference-paper
Abstract: Cellulose membrane is bacterial cellulose which produced from the fermentation process by Acetobacter xylinum.Cellulose membrane was performed in mixture liquid medium by using coconut water and sugar palm juice as the base medium.In this study, different present sugar concentrations including 0%, 7,5% and 10% were added into fermentation medium to enhance bacterial cellulose production.By adding three different sugar concentrations, the bacterial cellulose from different sugar concentration was made into cellulose membrane.Cellulose membrane were tested for physical properties of cellulose membrane, such as the degree of crystallinity by x-ray diffraction (XRD), water content and thermal decomposition behaviour by TGA, scanning electron microscopy analysis (SEM), tensile strength, FTIR spectra of cellulose membrane.The better cellulose membrane was reported from the addition of 7.5% sugar for all physical properties material.
