AbstractThis research aimed to produce bacterial cellulose through fermentation of kombucha symbiotic cellulose of bacteria and yeast (SCOBY) by using fruit peel wastes as fermentation substrates. This research is divided into three main studies, namely proximate analysis of fruit peel wastes, correlation studies of fermentation process and characterisation studies of kombucha SCOBY cellulose (KSC). The fruit peel wastes used in this study were dragon fruit, jackfruit banana, saba banana and pumpkin. Several proximate analyses were conducted to determine the composition of carbohydrate, protein, fibre and ash in fruit peel wastes. The characterisation studies of KSC were carried out using Fourier transform infrared (FTIR) spectrometer, X-ray diffraction (XRD) spectrometer, thermogravimetric analyser (TGA), differential scanning calorimeter (DSC), field emission scanning electron microscope (FESEM) and energy dispersive X-ray (EDX) spectrometer. Based on proximate analyses, dragon fruit peel wa.....
