- Abstract
Microalgae are prokaryotic or eukaryotic organisms that have photosynthetic anabolic activity. This anabolic photosynthesis is related to the abiotic factor of light. Therefore, this study aimed to identify the morphological diversity level of microalgae based on their environment, especially light intensity. We collected samples based on two types of environment, namely high light community (HL-1D and HL-2D) and low light community (LL-1D and LL-2D). The Data were analyzed using Species Richness Indices (Menhinick and Margalef indices), Species Diversity (Shannon-Wiener and Simpson Indices), and Eveness Index. Based on the results of morphological identification, we found the presence of algae from the divisions Cyanophyta, Chlorophyta, and Euglenophyta in both communities. The most dominant species found in the HL environment were Cyanophyta (Chroococcus sp., Microcystis sp., Nostoc sp., Oscilatoria sp.), Chlorophyta (Actinastrum sp., Ankistrodesmus sp., Centritractus belanophorus, Coelastrum sp., Closterium sp., Gleocapsa sp., Mougeutia sp., Pediastrum sp., Scenedesmus sp., Selenastrum sp., Sphaeroplea sp., Tetraspora cylindrica, Ulothrix sp., and Volvox sp.), Euglenophyta (Cryptoglena sp. and Lepocinclis sp.). Species found in the LL environment were Cyanophyta (Bulbochaeta sp.) and Chlorophyta (Pleurotaenium sp., Uronema elongasi, and Zygnema sp.). Microalgae communities in high light communities have higher diversity than low light communities. This study can be used as a reference for the diversity of microalgae in two different types of environments, especially in the tropics and in freshwater microalgae communities. This diversity data could be a reference for researchers and provide preliminary information of microalgae potency as alternative biofuels in the future.
