Characterization of Komagataeibacter xylinus by a polarization modulation imaging method
Journal of Physics D: Applied Physics, 2020Komagataeibacter xylinus (K. xylinus) has been used for a long time as one of the main cellulose producers among bacterium. In order to gain a better understanding of the physiological and biochemical mechanisms of cellulose production, an efficient and non-invasive visualization method is highly demanded to monitor the morphological changes of K ...

Gluconacetobacter xylinus (formerly Acetobacter xylinum and presently Komagataeibacter medellinensis) is known to produce cellulose as a stable pellicle. However, it is also well known to lose this ability very easily. We investigated the on and off mechanisms of cellulose producibility in two independent cellulose-producing strains, R1 and R2.

Kinetics of cell growth and crystalline nanocellulose production by Komagataeibacter xylinus
Biochemical Engineering Journal, 2017Abstract The mass transfer rate of oxygen often limits the cell growth of aerobic bacteria and its product formation. Baffles and agitation increase mixing and oxygen transfer. The effects of agitation rates on the cell growth and oxygen uptake rate (OUR) of Gluconacetobacter xylinus (G.

AbstractBacterial cellulose nanofiber (CNF) is a polymer with a wide range of potential industrial applications. Several Komagataeibacter species, including Komagataeibacter xylinus as a model organism, produce CNF. However, the industrial application of CNF has been hampered by inefficient CNF production, necessitating metabolic engineering for the ...

Bacterial cellulose (BC), prepared from two recently developed thermotolerant bacterial strains (Komagataeibacter xylinus C30 and Komagataeibacter oboediens R37-9), were used as a raw material to synthesize nanofibril films. Field-emission scanning electron microscope (FE-SEM) observations confirmed the ultrafine nano-structure of BC pellicle (BCP ...

Bacterial cellulose (BC) is a renewable biomaterial that has attracted significant attention due to its excellent properties and wide applications. Komagataeibacter xylinus CGMCC 2955 is an important BC-producing strain. It primarily produces BC from glucose while simultaneously generating gluconic acid as a by-product, which acidifies the medium and ...
