Taxonomic classification of algae by the use of chlorophyll a fluorescence

Abstract

Natural water reservoirs are very important ecosystems thus they should be under continuous monitoring and protection. In water of low quality, the algal blooms develop develops vastly. The knowledge of algal species composition is necessary for understanding this process. There are a few traditional group-specific methods of microalgae classification, but they are often labour-intense and time-consuming. Moreover, the samples must be prepared and/or collected before getting any results. Non-invasive chlorophyll fluorescence analysis offers an alternative approach and potentially allows in situ estimation of algal concentration. In this work the fluorometric methods to estimate algae content in water and to differentiate algal populations is presented.
