The biocompatible and biodegradable nature of BNC offers considerable advantages for its application in fields such as medicine, biomedical engineering, cosmetics, food, nanocomposites, and organoelectronics. Nevertheless, the high production costs necessitate the development of more cost-effective and efficient BNC production methodologies. This study aimed to produce BNC utilizing cost-effective sugar beet molasses. To achieve this, bacteria isolated from various vinegar samples were assessed, revealing that the BNC production potential of these isolates ranged from 2.09 to 3.21 g L-1. The 16S rDNA gene of the strain with the highest BNC yield was amplified and sequenced, and it was subsequently deposited in the GenBank database as Komagataeibacter sp. SB2569, with the accession number PV231799.1. XRD analysis revealed characteristic diffraction peaks at 14.8 degrees, 16.5 degrees, 22.6 degrees, and 34.5 degrees, confirming the cellulose 1 beta crystalline structure and high crystallinity of the synthesized BNC. FTIR analysis exhibited characteristic absorption bandsthat, confirming the presence of beta-1,4-glycosidic linkages and the cellulose I structure of BNC. TGA analysis showed an initial weight loss of similar to 5% between 0-100 degrees C, a major degradation of similar to 75% occurring at 220-350 degrees C with a maximum decomposition rate at 343 degrees C, and a residual mass of approximately 10-20% remaining above 600 degrees C. The findings indicate that the Komagataeibacter sp. SB2569 strain holds significant potential for BNC production using low-cost carbon sources.eninfo:eu-repo/semantics/closedAccessBacterial nanocelluloseKomagataeibacter sp.XRDFTIRTGADSCArticle81110.1007/s11756-025-02134-92-s2.0-105027435862Q2WOS:001662857600004Q3
