Bacterial Macroscopic Rope-like Fibers with Cytopathic and Adhesive Properties

Flagella bending affects macroscopic properties of bacterial suspensions.

To survive in harsh conditions, motile bacteria swim in complex environments and respond to the surrounding flow. Here, we develop a mathematical model describing how flagella bending affects macroscopic properties of bacterial suspensions. First, we show how the flagella bending contributes to the decrease in the effective viscosity observed in dilute suspension. Our results do not impose tumb...

Preparation and Properties of Bacterial Cellulose/Alginate Blend Bio-Fibers

Correspondence to: Shuai Zhang email: [email protected] ABSTRACT LiOH/urea/thiourea aqueous systems have been successfully applied to the dissolution of bacterial cellulose (BC) and alginate (AL) to prepare blend fibers. Morphology, compatibility and mechanical properties of the blend fibers were investigated by scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FT...

Physiochemical properties of Caulobacter crescentus holdfast: a localized bacterial adhesive.

To colonize surfaces, the bacterium Caulobacter crescentus employs a polar polysaccharide, the holdfast, located at the end of a thin, long stalk protruding from the cell body. Unlike many other bacteria which adhere through an extended extracellular polymeric network, the holdfast footprint area is tens of thousands times smaller than that of the total bacterium cross-sectional surface, making...

Cellulose fibers and nanofibrils for adhesive reinforcement

Introduction In wood industry, adhesive bonding is one of the key process steps. To ensure continuing technological progress in wood industry it is necessary to explore new possibilities of improvement in adhesive bonding. The potential routes for performance improvements suggested by a state of the art report issued by COST Action E13 Wood Adhesion and Glued Products (Dunky et al. 2002) focus ...
