Production of bacteria cellulose from hydrolysate of banana, sago, and potato wastes

Introduction: This article studies the bacterial cellulose (BC) produced using hydrolysates obtained from three Malaysian domestic agricultural wastes which are banana peels, potato peels, and sago effluent. Methods: The wastes were hydrolysed using sulphuric acid at concentration of 4% (v/v) or 6% (v/v) for 20 minutes at two different temperatures, 105°C and 121°C, before being used as a carbon source in a culture media for the production of BC. Results: Banana peel hydrolysate produced the highest BC yield (2.89 g/L) compared to potato peel hydrolysate (2.42 g/L) and sago effluent (0.38 g/L). However, the potato peel hydrolysate contains a higher glucose concentration (43.44 mg/mL) than banana peel hydrolysate (19.15 mg/mL). It was investigated that pH 6 as the initial pH of fermentation media and 2.0% of initial carbon source concentration are the best conditions for the fermentation of BC using banana peel hydrolysate as a carbon source. The morphology of BC produced from banana peel hydrolysate captured by SEM has ultrafine fibrils and a pore-like reticulated structure, similar to BC produced from standard HS media. Conclusion: This study showed that banana peel hydrolysate is a promising carbon source for BC production, yielding the highest BC yield with desirable characteristics. In addition, the optimal fermentation conditions were identified in this study, which is useful for large-scale or industrial production.
