====== Bacterial gliding ======

Many species of bacteria have the ability to move over smooth surfaces - in a process named 'Gliding'. It's a key part of bacterial proliferation, and is used not only to access resources, but also to avoid adverse conditions (e.g. U.V. light sources).

It has been studied for more that 100 years, and in most cases is not understood.

In //Cytophaga hutchinsonii //for example, which can move rapidly over surfaces, the mechanism has been shown //not// to involve [[content:life_sciences:zoology:flagella|flagelae]], but is powered by some as yet unknown mechanism (ref. [[https://genome.jgi.doe.gov/portal/cythu/cythu.home.html|US D.O.E.]] )

It's likely that different species might use different techniques - there are at least six proposed mechanisms currently under investigation - see [[https://en.wikipedia.org/wiki/Gliding_motility#Proposed_mechanisms|Wikipedia]]

As well as the biological interest in trying to understand the motion, there is also interest from nano-tech and bio-computation groups interested in exploring possible ways to move nano-structures in the so-called 'Lab-On-A-Chip'.
