Where are they found? Biomass on the planet.

 Most culturing analysis misses over 99% of the microbial population.

 Molecular techniques now reveal hidden diversity

 Heterotrophs - 5-20% biomass in sea waters - up to 80% of the primary production

 Rich bacterial communities in sub-surface strata (600 m deep) - up to 2 x 1014 tons - more than all flora and fauna -equivalent to  2 m layer over planet!
