Original Abstract

Bacterial cellulose (BC) is an extracellular polysaccharide produced by many bacterial strains as a protective barrier against environmental stress. It has unique mechanical and physical properties that support diverse applications across fields such as medicine, cosmetics, electronics, textiles, food, and biotechnology. However, the high production costs of BC limit its broader application. The food and agricultural industries generate waste rich in sugars and hemicellulose/cellulose, which can serve as carbon sources for bacterial cultivation. Approximately one-third of all food produced globally is wasted annually. This study focuses on utilizing carbon sources derived from grape pomace, banana peels, and by-products of lignin extraction. These carbon sources were prepared through hydrolysis of the aforementioned waste materials, and the resulting hydrolysates were directly used in cultivation media preparation for Komagataeibacter xylinus. Additionally, morphological and rheological properties of BC produced with modified media were examined. The tested hydrolysates proved to be suitable carbon sources for cultivating K. xylinus, yielding higher amounts of BC compared to standard media. Morphological analysis showed some changes to porosity and fibril thickness, while viscoelastic properties were only marginally affected.
