Abstract

The existence of starch in the formation of bacterial cellulose was found to have the capability to enhance the viscosity of culture medium, thus it can affect the agitation process. The aim of this study was to investigate the morphological structure of bacterial cellulose/cassava starch (BC/CS) nanocomposites produced by in-situ process in agitated culture. The fabrication of BC/CS was carried out at 28°C for 7 days under agitated condition at 100 rpm with five different masses of CS. The crystallinity of BC/CS nanocomposites was studied by using X-ray Difraction (XRD) pattern, whereas the morphological structure was discovered from the digital photograph, optical microscope (OM) picture and scanning electron microscope (SEM) pictures. From the SEM analysis, it was observed that the cassava starch layer had occupied the pores of the fibre network of bacterial cellulose and increased the average size of the fibres. Also, it was well dispersed in the network of bacterial cellulose. The high content of starch on the culture caused the changes in orientation of the nanocomposites’ surface morphology and reduced the shaking effect of the culture. The study found that the BC/CS nanocomposites with variation of 5 g CS showed the best morphological properties.
