The rapid uptake and remineralization of dissolved free monosaccharides by heterotrophicbacteria account for the barely detectable levels of these compounds.
2
This minireview summarizes current knowledge regarding the exudation and composition of phytoplankton-derived exopolysaccharides and acquisition of these compounds by heterotrophicbacteria.
3
Either readily oxidizable carbon or plant polymers were used as the sole carbon and energy source to isolate heterotrophicbacteria from these soils.
4
Heterotrophicbacteria always showed the highest densities, and diatoms showed the lowest, but the relative abundances of these groups varied depending on the coating.
