Abstract |
The bacterial uptake of several 14C-labelled amino acids and of a mixture of 14C-labelled amino acids (an algal protein hydrolysate) was measured during a one year period in the saline Lake Grevelingen and the more eutrophicated, freshwater Haringvliet basin in the Netherlands. The yearly uptake capacity as determined with the 14C-labelled amino acid mixture was only 2.8% (Lake Grevelingen) and 3.7% (Haringvliet) of the amount of mineralized carbon, as calculated from oxygen uptake experiments. These percentages are very low in view of the fact that 35 to 55% of the organic matter of phytoplankton and zooplankton consists of protein, and that the aerobic mineralization of amino acids is a very common property among the heterotrophic bacterial population. |
