Microalgae are considered one of the most promising microorganisms for sustainable production of food products. In order to maximize the biotechnological potential of microalgae, further information on their metabolism is still needed. Gas chromatography (GC) is advantageous for the metabolites’ analysis, since it allows the separation and detection of several organic compounds, among them volatiles, amino acids, organic acids, carbohydrates, fatty acids and sterols from different sample preparation, come under with high resolution and sensitivity. In addition to the monitoring and optimization of the microalgal bioprocesses, GC analyses also aid in the characterization and verification of the biomass quality obtained at the end of the cultivation. Thus, the use of GC shows great potential of monitoring of important metabolites for the development of microalgae bioprocesses.
