Chlorophyll a cyanobacteria
WebJun 27, 2024 · cyanobacteria A large and varied group of bacteria which possess chlorophyll a and which carry out photosynthesis in the presence of light and air, with concomitant production of oxygen. They were formerly regarded as algae (division Cyanophyta) and were called ‘blue- green algae ’. WebThe cyanobacteria that produce cyanotoxins endanger both the aquatic ecosystem and human health. To evaluate and reduce the impact of potentially harmful species, it is crucial to monitor and model algal blooms and their composition.
