Microalgal Diversity of Middle Rift Valley Lakes (Arenguade and Killole) Oromia Region, Ethiopia

Microalgae have been one of the richest and most promising sources of bioactive primary and secondary metabolites and their discovery has significantly expanded in the past decades. The aim of the study was to assess the diversity of microalgae in Lake Arenguade and Kilole. Lake Arenguade and Killole are an alkaline soda lakes located in Bishoftu, Ethiopia. Sampling of the two lakes and data were collected during February 2016. The preserved Microalgal samples and the fresh water samples grow on liquid media (BBM and BG-11) were examined using binocular microscope and their identification to genus or species level were made on the basis of various descriptors of Microalgae. The result indicated that Arthrospira is dominant species in Lake Arenguade and maximum diversity index showed in two lakes by phylum Chlorophyta and other Cyanobacteria genera were common in Lake Killole.
