Mixed Food Waste as a Low-Cost Carbon Source for Kombucha Bacterial Cellulose
Abstract
= 30 min (HJ-30 min) at 5.44 g/L. The yields achieved using the mixed food waste substrates (UJ and HJ-30 min) were substantially higher than those from refined sugar (RS) and 2% acetic acid only (Ac2) controls. Acetic acid hydrolysis (2% v/v, 30 or 100 min) significantly reduced the initial sucrose concentration from 41.75 g/L to 2.7× greater than that of microcrystalline cellulose (MCC)), and scanning electron microscopy (SEM) micrographs revealed characteristic nanofibrillar morphologies. These results demonstrate that unhydrolyzed mixed food waste is not only sufficient but preferable for BC production, offering a low-cost, minimally processed pathway to obtain high-quality, high-purity biopolymers with numerous applications.
