Investigation of Carbon Content Analysis of Chlorella vulgaris and Nannochlropsis Oculata Using TOC Analyzer for CO2 Bioremediation and Biofuel Production

Global warming is become a current issue that world seek to find a solution to it through mitigation of the greenhouse gases. Carbon dioxide (CO₂) is one of the well-known greenhouse gases, which mainly came from human activities because of industrialization. Different CO₂ capture strategies have been suggested and the most attractive one is the combined carbon capture and wastewater treatment using microalgae. Microalgae can utilize CO₂ to increase its biomass which can be converted to a valuable biofuel products by conversion methods whether its thermochemical, biochemical, or chemical reaction based technology. Thus, characterization of the microalgae biomass for its carbon content is a decisive criterion for the selection suitable of conversion method. TOC analyzer is used to measure total organic carbon for Chlorella vulgaris, Nannochloropsis oculta, microalgae species. The effect of CO₂ concentration in the growth of microalgae and the amount of carbon produced is investigated. The increasing of the carbon content during microalgal biomass growth is well determined.
