The assessment of nutrient availability for the growth of freshwater green algae Chlorella kessleri by bioassay (Lake Sakadaš, Nature Park Kopački Rit)

In the water of Lake Sakadaš, concentrations of nitrates and total nitrogen decreased from March to July 2005. In untreated water samples, the availability of nitrogen limited the growth of C. kessleri. A significant increase in the growth rate of C. kessleri in water samples enriched with nitrogen indicated N limited conditions in June and July. The increase of the degree of algal response to N enrichment from March to July 2005 was probably a result of the decrease of nitrogen availability.
