Environmental concerns have taken a center stage in our lives driving the society towards biorefinery. Bioprocess development to produce valuable products utilizing waste has its own significance in circular bioeconomy and environmental sustainability. In the present study, production of bacterial cellulose using pineapple waste as carbon source by Komagataeibacter europaeus was undertaken and it was applied for removal of vanadium, a heavy metal which is generated as waste by semiconductors industry in Taiwan. Highest yield of bacterial cellulose (BC) e.i. 5.04 g/L was obtained with pineapple core hydrolysate (HS-PC) replacing glucose in HS medium. The vanadium adsorption capacity by BC produced by HS medium was 5.24 mg/g BC at pH 4 and 2.85 mg/g BC was observed on PCH medium. BC was characterised via SEM, FTIR and XRD.
环境问题已在我们的生活中占据核心地位，推动社会朝着生物炼制方向发展。利用废弃物生产有价值产品的生物工艺开发在循环生物经济和环境可持续性方面具有自身的重要意义。在本研究中，以菠萝废弃物作为碳源，由欧洲鞘氨醇杆菌生产细菌纤维素，并将其用于去除钒，钒是台湾半导体行业产生的一种重金属废弃物。用菠萝芯水解物（HS-PC）替代HS培养基中的葡萄糖时，细菌纤维素（BC）的产量最高，即5.04 g/L。HS培养基生产的BC在pH值为4时对钒的吸附容量为5.24 mg/g BC，在PCH培养基上观察到的吸附容量为2.85 mg/g BC。通过扫描电子显微镜（SEM）、傅里叶变换红外光谱（FTIR）和X射线衍射（XRD）对BC进行了表征。
