Abstract
Effects of nutrient conditions on biochemical components (sugars and amino acids) of phytoplankton were examined in Lake Nakanuma in Japan. Phosphate, ammonium and silicate were added to water samples collected at 0 m, which were incubated for 15 days in situ. Chlorophyll a in phosphate-added samples increased much more than that in other samples. Total amino acids and total neutral sugars in phosphate-added samples also increased more than those in other samples. The increase of total amino acids and chlorophyll began faster than that of total neutral sugars during the first 5 days of incubation. Total neutral sugars in the phosphate-added samples increased rapidly after 8 days. The composition of amino acids did not change so much. However, the composition of neutral sugars changed according to the different nutrient addition. Phosphate-added samples changed greatly during the incubation. These changes were explained at least partly by changes in nutrient conditions. Addition of limiting nutrients decreased glucose content, whereas depletion of nutrients increased the content. This study indicates that measurements of the biochemical components contribute to the analysis of effects of nutrients on phytoplankton in natural waters.
