Characterization of a novel cellulose biosynthesis inhibitor, CBI28, in Gluconacetobacter xylinus
… a CBI28-Biotin conjugate for further studies. Gluconacetobacter xylinus cells were exposed to 10 uM CBI28 to induce cellulose biosythesis inhibition, lysed and small hydrophobic molecules were extracted using methanol and Waters Oasis HLB SPE-Paks. Samples were separated and detected using the …

Purification and characterisation of novel recombinant β-glucosidases from aspergillus with application in biofuel production
… Bacterial cellulose (BC) was produced by Gluconacetobacter xylinus. For the first time a fully detailed characterization by Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), X-ray diffraction (XRD), Differential scanning calorimeter (DSC), …

Antibiotic-free antibacterial hydrogels for wound healing applications
… First, the production of BC by fermentation of Gluconacetobacter xylinus and its purification from the biomass were optimised. The material was characterised with respect to its morphological, chemical and mechanical properties. The introduction of antibacterial functional groups was then …

Liposome-loaded biosynthetic bacterial cellulose hydrogels for wound management applications
… cellulose hydrogels were synthesised by Gluconacetobacter xylinus (ATCC 23770) and loaded with antimicrobial agents. Characterisation studies were carried out on these biosynthetic hydrogels for their wound healing properties. Due to the rise of antibiotic resistant bacterial strains, …
