Abstract: To reduce the cost of obtaining bacterial cellulose (BC) and increase the value of fruit processing waste, the use waste from banana peel (BP) and passion fruit peel (PFP) as a carbon source
for the production of bacterial cellulose (BC) by Komagataeibacter nataicola TISTR 2661 was developed.
BP and PFP were digested with commercial saccharifying enzymes and the sugar content of these
aqueous extracts reached 0.57±0.01 g/g- substrate (35.20±1.60 g/L) and 0.31±0.00 g/g- substrate
(15.05±0.07 g/L), respectively. After 9 days of incubation, the BC production of BP and PFP aqueous
extracts K. nataicola TISTR 2661 were 0.89±0.04 g/L and 0.31±0.07 g/L, respectively. To enhance the
BC production, the aqueous extracts of BP and PFP were supplemented with MgSO4, KH2PO4 and
(NH4)2HPO4. The addition of KH2PO4 1 g/L increased the BC production yield from BP aqueous
extracts by 13.85±1.18%, which is higher than the yield from Hestrin & Schramn (HS) medium of
6.13±1.50%. The BC membrane was characterised by scanning electron microscope (SEM) and
fourier-transform infrared spectroscopy (FTIR), which demonstrated that the aqueous extracts from
BP and PFP could be used as carbon sources for the production of BC with low value residues. |
