Fast moving bacteria (motility)

Postby CilicThePotro » Thu Jul 21, 2011 6:30 am

Hi Guys,

Ive been looking at E. Coli under a microscope for the investigation of motility. Not just weather they move but how fast they go, and what % are motile. So far Ive got quite a lot of data with E. Coli and i'd like to try something else. The problem is I didnt study biology so Im not sure where to start. I have a list of what bacterial stocks are avaliable, but all they say are if its motile or not.

So far ive found this http://www.youtube.com/watch?v=M5YEu4qD13I. These 'Pseudomonas aeruginosa' are avliable to me (lots of different strains). Does that mean if i get a culture, and grow it overnight they should swim that quickly for me?

Does anyone know of the top of their head a very fast moving bacteria thats under 2um in size? When I say very fast i mean 50um/s ++. The e-coli I look at swims about 15 um/s at 20 degrees, maybe 30um/s at 30 but i cannot increase the temp under the microscope.



Thanks
