Polyhydroxybutyrate-Based Nanocomposites with Cellulose Nanocrystals and Bacterial Cellulose

Journal of Polymers and the Environment, 2016
Polyhydroxybutyrate (PHB) films nanoreinforced with hydrolyzed cellulose nanocrystals (CNC) and bacterial cellulose (BC) were prepared by solvent casting. The influence of different cellulose nanoparticles content (2, 4 and 6 wt% of CNC and 2 wt% of BC) on the PHB properties was studied. CNC nanocomposites presented good dispersion of the nanocrystals,

Bacterial cellulose

2004
A strain of Acetobacter xylinum was isolated from the New Zealand environment. The characteristics affecting cellulose production by A. xylinum were investigated and compared to previously isolated strains. The effect of various environmental parameters on the mechanical strength and water holding capacity of the bacterial cellulose was also ...

Carboxymethylation of Bacterial Cellulose

Macromolecular Symposia, 2010
AbstractThe carboxymethylation of bacterial cellulose (BC) was studied under typical heterogeneous reaction conditions. It was found that the BC possesses a significantly lower reactivity compared to wood cellulose converted under comparable conditions.

Bacterial Cellulose as Biomaterial

2011
Cellulose is a biopolymer that has long been used as a biomedical material and is still used in a modified form in hemodialysis membranes and as a carrier material in drug release systems. The different sources of cellulose that have not yet been fully explored, for example, bacterial cellulose (BC), might possess properties that are needed for some ...

Effect of cellulose crystallinity on bacterial cellulose assembly

Cellulose, 2016
Bacterial cellulose (BC) is a promising biomaterial as well as a model system useful for investigating cellulose biosynthesis. BC produced under static cultivation condition is a hydrous pellicle consisting of an interconnected network of fibrils assembled in numerous dense layers. The mechanisms responsible for this layered BC assembly remain unknown.

Bacterial Cellulose Nanocomposites

2019
Bacterial cellulose (BC) is a biopolymer with high purity of cellulose and excellent mechanical properties. Increased interest in the use of natural polymer makes BC as an excellent alternative for plant cellulose. Although both celluloses consist of unbranched pellicle with chemically equivalent structure, bacterial cellulose exhibits greater ...

Cellulose in Bacterial Biofilms

2019
Many bacteria produce cellulose as an exopolysaccharide component of the extracellular matrix in biofilms, which are large aggregates of bacterial cells often attached to abiotic or biotic surfaces. Cellulose has been particularly well studied in two model bacteria, Komagataeibacter xylinus and Escherichia coli. The widely conserved bacterial cellulose

The structure of bacterial cellulose

Biochimica et Biophysica Acta, 1949
Abstract Electron microscopic observations show that the cellulose built by Acetobacterium xylinum occurs in the form of fibres having about the same diameter (ca 250 A) as that of the fibrils of cellulose from the cell walls of nemerous plants.
