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

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

Unlike animal cells, bacteria have no cytoskeleton. Shape maintenance and, to some extent, cell-cycle regulation are governed by the cell wall. The walls of many rod-shaped bacteria are continuously added to on the inside surface, at the cytoplasmic

Turgor pressure in bacterial cells has been known for a long time (Mitchell and Moyle, 1956). It is therefore surprising that the first attempt to relate it to cell shape was not made until 12 years ago (Koch et al., 1981). The basic idea, as later e

Bacterial macrofibers twist as they grow, writhe, supercoil and wind up into plectonemic structures (helical forms the individual filaments of which cannot be taken apart without unwinding) that eventually carry loops at both of their ends. Terminal

Bacillus subtilis macrofibres exposed to lysozyme underwent characteristic rotations, termed relaxation motions, in which their twist changed. Intact macrofibres and macrofibre fragments devoid of loop ends responded in the same way. Macrofibre strai

Bacterial macrofibers are multicellular structures produced by certain cultures of rod-shaped cells when cells do not separate from one another after septation. Chains of cells arise that twist as they grow. This twisting is thought to reflect either

Bacterial threads of up to 1 m in length have been produced from filaments of separation-suppressed mutants of Bacillus subtilis. Individual threads may contain 20,000 cellular filaments in parallel alignment. The tensile properties of bacterial thre

Static and dynamic studies of helical Bacillus subtilis macrofibers reveal that a spectrum of twisted states exists ranging from tight left-handed structures with twist equal to approximately equal to 40 left turns per mm to tight right-handed struct

Bacterial thread is the name given to a fibrillar fiber produced from cell-separation-suppressed mutants of Bacillus subtilis. which grow in long cellular filaments and produce in cultures aggregates that resemble randomly-laid textile webs. Threads
