Experimental Identifications of Fresh Water Microalgae Species and Investigating the Media and PH Effect on the Productions of Microalgae

Identifying predominant species around marine system is essential to propose a project for harvesting those species which can be used for colored waste treatment, biofuel production, for cosmetics and carbon sequestration. The objective of this study was to investigate the co-culture microalgae species and identifying the predominant fresh water microalgae species. The production of microalgae (mixed culture) in photobioreactor configurations was investigated using two different media formulations in batch operation. The predominant co-cultured freshwater microalgae species Scenedesmus sp., Chlorella sp., Synedra sp. and Achnanthidium sp. were investigated in batch culturing media and Effect of culturing media( BB Medium and BG-11 Medium) for effective algal growth were determined. The Bold basalt medium has somehow high optical density value than the BG-11 medium and the maximum biomass concentration was found 0.608 g/L in the Bolt basalt medium and 0.5624 g/L in BG-11 medium for 15 day cultivation time. The study revealed that amount of time required to adapt the culturing environment is not differed significantly in both growth medium type. Also PH range has an effect on the mass productions of algae. The optimum PH for high productions of mixed culture microalgae were investigated at pH 8.
