Abstract
Bacterial cellulose (BC) is widely used due to its distinct physicochemical properties when compared to
plant cellulose. BC is primarily concerned with the biosynthetic process in order to achieve low-cost
preparation and high cellulose production. BC has displayed significant advantages over cellulose
obtained from plants due to the absence of lignin, hemicellulose, pectin, and other contaminating
materials of animal origin. Hence, it possesses high purity, crystallinity index, and biocompatibility. This
study aims to isolate cellulose-producing bacteria from Carica papaya and characterize the bacterial
cellulose produced using SEM, FTIR, XRD. Initially, the fermentation of the isolates was carried out
under static and agitated fermentation with an initial pH of 6, a temperature of 37°C, and a fermentation
period of 14 days. Isolate PP4 produced approximately 1.22g/mL pellicles under static condition at 37ºC
for 14 days. Some FTIR peaks of the pellicle analysed indicate the absence of a hydrogen bond, while
sharp intensity peaks contain an oxygen-related group. There is also a narrow band indicating the
presence of aliphatic compounds. A fingerprint peak shape representing the aromatic ring and Vinylrelated compound was also detected. XRD analysis revealed 15 distinct diffraction peaks, indicating
that the pellicle belonged to the monoclinic type with 95.0% of crystallinity index. Lastly, the SEM images
showed that the pellicle had clustered microfibrils, non-microfibrils cellulose interaction, which had gaps
between the fibres and not intertwined closely.
