"In an
example from a different aquatic environment, an
oligotrophic lake, the large (270µm^3) motile
bacterium Chromatium okenii was found to be
responsible for >40% of total ammonium uptake
and >70% of total carbon uptake, despite accounting
for only 0.3% of the total cell number
(ref 33). In contrast, the small (1.2µm^3) nonmotile
Chlorobium clathratiforme only contributed 15%
to total ammonium uptake and 15% to total
carbon uptake, despite having a 100-fold larger
numerical abundance and a 10% larger total biovolume
compared with C. okenii." |
