To address the high production cost associated with bacterial cellulose (BC) production using the Hestrin-Schramm (HS) medium, alternative agricultural wastes have been investigated as potential low-cost resources. This study aims to utilize pineapple core from pineapple canning industry waste as a carbon source to enhance the bacterial growth of and to characterize the physical and mechanical properties of the resulting BC. To assess growth performance, commercial sugar at concentrations of 0, 2.5, and 5.0 % (w/v) was incorporated into the medium. Fermentation was conducted under static conditions at room temperature for 5, 10, and 15 days. The structural and physical properties of BC were characterized using SEM, FTIR, XRD, and DSC. With the exception of crystallinity, BC produced from the pineapple core medium exhibited comparable characteristics to BC produced in the HS medium. These findings highlight the potential of utilizing pineapple core, a byproduct of the canning industry, as an economically viable nutrient source for BC production.
为了解决使用赫斯特林 - 施拉姆（HS）培养基生产细菌纤维素（BC）所带来的高生产成本问题，人们对替代农业废弃物作为潜在低成本资源进行了研究。本研究旨在利用菠萝罐头工业废弃物中的菠萝芯作为碳源，以促进细菌生长，并对所得细菌纤维素的物理和机械性能进行表征。为评估生长性能，将浓度为0%、2.5%和5.0%（w/v）的商业糖添加到培养基中。在室温静态条件下进行5天、10天和15天的发酵。使用扫描电子显微镜（SEM）、傅里叶变换红外光谱仪（FTIR）、X射线衍射仪（XRD）和差示扫描量热仪（DSC）对细菌纤维素的结构和物理性能进行表征。除结晶度外，由菠萝芯培养基生产的细菌纤维素与在HS培养基中生产的细菌纤维素表现出相似的特性。这些发现突出了利用菠萝芯（一种罐头工业的副产品）作为细菌纤维素生产中经济可行的营养源的潜力。
