Filamentation is the anomalous growth of certain bacteria, such as Escherichia coli, in which cells continue to elongate but do not divide (no septa formation). [ 1 ] [ 2 ] The cells that result from elongation without division have multiple chromosomal copies.
An interesting aspect of the filamentation induced plasma is the limited density of the electrons, a process which prevents the optical breakdown. [17] This effect provides an excellent source for spectroscopy of high pressure with low level of continuum and also smaller line broadening.

Filamentation Filamentation allows bacteria to have more surface area for long-term attachments and can interlink themselves with porous surfaces. Caulobacter crescentus : in their niche (freshwater), filament is the regular shape that contributes to their resistance to heat and survival.
Filamentation also refers to the self-focusing of a high power laser pulse. At high powers, the nonlinear part of the index of refraction becomes important and causes a higher index of refraction in the center of the laser beam, where the laser is brighter than at the edges, causing a feedback that focuses the laser even more. The tighter ...
Inhibition of FtsZ disrupts septum formation, resulting in filamentation of bacterial cells (top right of electron micrograph). During cell division, FtsZ is the first protein to move to the division site, and is essential for recruiting other proteins that produce a new cell wall between the dividing cells.
Filamentation modes: growth leads towards the breakup of the beam into separate filaments. Gives an elliptic cross-section m=3: ... This section does not cite any ...
This causes filamentation, and the induction of UmuDC-dependent mutagenic repair. As a result of these properties, some genes may be partially induced in response to even endogenous levels of DNA damage, while other genes appear to be induced only when high or persistent DNA damage is present in the cell.
