Growing Bacillus subtilis macrofibers use twist and supercoiling to: power their own self-assembly, join fibers together into multiclonal aggregates, move themselves over solid surfaces, and to drag other structures (cargo) over solid surfaces. The d

The swimming motions of cells within Bacillus subtilis colonies, as well as the associated fluid flows, were analyzed from video films produced during colony growth and expansion on wet agar surfaces. Individual cells in very wet dense populations mo

Organized bacterial superstructures have been used as 3-D templates for the fabrication of ordered inorganic−organic fibrous composites. Preformed magnetic (Fe3O4) and semiconducting (CdS) inorgani...

In this review, we describe four approaches to the materials synthesis of organized inorganic matter. These include the use of self-assembled organic templates (transcriptive synthesis), cooperative assemblies of templates and building blocks (synerg

The synthesis of inorganic frameworks with specified and organized pore networks is of potential importance in catalysis1,2, separation technology3 and biomaterials engineering4,5. Ordered arrangements of porous channels have been produced in silica-

The twisting and writhing during growth of single-cell filaments of Bacillus subtilis which lead to macrofiber formation was studied in both left- and right-handed forms of strains FJ7 and RHX. Filament bending, touching, and loop formation (folding)

Nanometer-scale ferromagnetic particles (Fe2O3, Fe3O4) are dispersed within a mutant bacterial chain which is drawn into a macroscopic fiber “rope.” Cross-sectional scanning electron microscopy images reveal that the iron oxide particles are inte

Macroscopic magnetic bacterial threads are formed in which 10 nm Fe/sub 3/O/sub 4/ particles are intercalated between cell walls. A mutant strain of bacteria is used which forms long filaments of joined cells. Using a drawing technique these strands

Bacillus subtilis macrofibres, highly ordered multicellular structures, undergo twisting and writhing motions when they grow in fluid medium as a result of forces generated by the elongation of individual cells. Macrofibres are denser than the fluid
