I have often wondered how the folk who model global warming and so on deal
with this. How *do* they parametrise CO2 fluxes to and from e.g. the ocean
when, as Mark says, 99-99.9% of the bugs don't plate out? Anyone know?
 
I'd also include 'people' in the definition of the environment - we really 
seem to have very little good knowledge about e.g. factors that trigger
'reinfection' by bugs that didn't plate out but were still inside us after
a treatment with antibiotics. Mycobacteria (TB) are renowned for this, but 
I understand that most other bugs can probably do it too.

IMHO, the BIG question in (micro)biology generally is how the inside of the
cell is organised - too much of our thinking and modelling is still such
that the implicit view is the 'bag-of-enzymes', which it definitely aint.
