Fabrication of bio composite from bacterial cellulose/starch

Bio composite from starch and bacterial cellulose offer good mechanical properties. The objective of this study was to fabricate bio composite from starch, and bacterial cellulose.The research was conducted with 25 samples with difference composition of bacterial cellulose (BC)(0, 7, 14, 21 and 28)w...
