Petri dishes or equivalent then. Of course in case the bacteria on the
surface can be more or less quantitatively transferred to tubes (glass,
corex or comparable for centrifugation purposes, preferably with
screw-caps). I am sure that I know about Acetobacter even less than you
though. So, at least colony counting method recommended earlier should work.
However, given the amount of work involved I did not think that would fall
under "simple way" category requested in the original post :-), but it,
again, depends what is simpler, to buy a colony counter or a spec., or
analytical balance with at least 5 digit accuracy.
