Development of fertilizer-based medium for the growth rate improvement of Chlorella sp. in the laboratory scale
Abstract Microalgae are unicellular photosynthetic microorganisms, ubiquitous in nature which can be found in freshwater, seawater, hypersaline lakes, even in deserts and arctic ecosystems. Chlorella sp. is a eukaryotic, unicellular, photosynthetic organism with a spherical shape of about 1 to 20 μm...
