| Abstract: | A pico sized Synechococcus species isolated from Lake Balaton was studied in batch and continuous cultures. This picocyanobacterium had a pH optimum at 8.5 and a temperature optimum at 28-30°C. The Ik value for growth was 52 μEinstein m?2 S?1, the maximum growth rate 2.27 d?1, the half saturation Constant of growth 1.2 μg PO4-P I?1 and the minimal cell quota 1.74 nig P g dry weight?1. The dry weight of cells showed a minimum, the chlorophyll-a/biomass ratio a maximum as a function of growth rate. Above the quota of 3.4 fg P Cell?1 significant amounts of non-reactive dissolved Phosphorous were released. |
