Dear Sheinach,
I do not know whether T can fully satisfy you with this answer.
The rate of any biochemical reaction is dependent [and mostly proportional] to
the concentration of the substrate. So, this answers your 10 fold dilution
situation.
The 10 fold higher may negatively affect due to its osmotic pressure.
However, recently I have come across some work [unpublished] wherein the
organisms show opt growth rates at 1/100 - 1/1000 dilution of media containing
1% glucose. The ongoing work suggests that these may be totally new species
not cultivated so far!
