Abstract
The present study was conducted to purify, describe and identify the microalgae strains collected from Tabeyo Lake, Kabayan, Benguet Province. The study aims to increase the gene bank that can serve as resource to select suitable strains for any practical applications which will greatly benefit the society considering the microalgae play an important role in science and technology today. Two microalgae were described and molecularly identified as Scedenemus acutus (Meyen an Desmodesmus denticulatus (lagerheim), respectively. DNA sequences of D. denticulatus (Lagerheim) was analyzed and confirmed through the BLAST online tool with a percentage identity of 92.51%. The bootsrap value of every organism were shown in the phylogenetic three analysis and results show that the value of D. denticulatus (lagerheim) with Acutodesmus deserticola and Scedenesmus bijugus is 70% which confirms that they belong to the same species. lastly, the D. denticulatus is monophyletic with Desmodesmus baconii, paraphyletic wiuth S. bijugus and polyphyletic with Daedalea flavida strain.
