Bacteria have been usually assumed to play a major role in regeneration processes or in conversion of refractory compounds into bacterial biomass. Recent studies have shown that heterotrophic bacteria can specifically select inorganic nutrients to promote their growth. Bacterial uptake of inorganic nutrients would take place when organic substrates (i.e. nitrogen or phosphorus) are limited. Therefore, especially in oligotrophic systems, bacteria would compete with microalgae for inorganic nutrients. However, experimental evidences indicate that bacteria, even in non-limiting conditions, sometimes prefer inorganic nutrients to dissolved organic substrate. This may have significant consequences in terms of adaptive strategies and diversity of bacterial assemblages. the competition between heterotrophic bacteria and phytoplankton for inorganic nutrients implies a strong modification of the classical aquatic food web and new elements to include in the schematic concept of microbial loop. |
