acetobacter xylinum growth rate?

Just thinking off the top of my head. How about:

1 - set up a simple broth culture with a known amount of organism. Proof can
be made with a simple colony count of a measure amount spread on an agar

2 - incubate at the optimum temp (or even use different temps). and perform
colony counts at different intervals.

3 - plot the results and calculate the growth rate and the generation time.

The colony counts would have to be done on serial dilutions until you can
get a countable number of colonies.
