These microorganisms are highly adaptive to changing environmental conditions. In this study, the occurrence of toxin producing cyanobacteria in Laguna de Bay and factors affecting its occurrence and growth were determined. The presence ofMicrocystis aeruginosa was positively correlated with nitrate （NO3） and iron （Fe^2＋） with correlation coefficient of ＋0.72972 and ＋0.91063, respectively. It is negatively correlated with occurrence of sunshine （in days） and turbidity with correlation -0.79055 and -0.93531, respectively.展开更多
