Temperature Effect on Exploitation and Interference Competition among Microcystis aeruginosa, Planktothrix agardhii and, Cyclotella meneghiniana
Table 2
Nutrient concentrations of cells free culture filtrate of M. aeruginosa (MIJAC), P. agardhii (PAT), C. meneghiniana (CCAP) and three culture (MIJAC + PAT + CCAP) at 18°C and 30°C, before and after nutrients replenishment. LOD: level of detection. LOD for NO3 + NO2: 0.01 mg L−1; LOD for PO4: 4 µg L−1; LOD for NH4: 0.02 mg L−1.
