dc.description.abstractVolatile organic compounds (VOCs) from microalgae have many applications in several industries, and their synthesis can be affected by several factors, such as light and growth phase. Thus, this study aimed to determine the influence of different irradiances and growth phases on the VOC profile of Arthrospira platensis and Chlorella sp. Biomasses of cultures subjected to 200 and 1000 µmol photons m−2 s−1 and harvested in the exponential and stationary growth phases were analyzed by gas chromatography and mass spectrometry. Twelve VOCs were found in the biomasses of A. platensis and 34 in the biomasses of Chlorella sp., with only five compounds in common for both species. In the biomasses of A. platensis, many hydrocarbons were found, being this class the one with the greatest representative in this species VOC profile. Octadecane, which may have several applications in the food industry, was the predominant compound, showing high values under 1000 µmol photons m−2 s−1 in the stationary growth phase. On the other hand, in Chlorella sp. biomasses, a variety of nitrogenous compounds was found, and octadecyl vinyl ether had the highest values under 200 µmol photons m−2 s−1 in the stationary phase. A couple of terpenoids were found in both microalgae, except safranal, which was only detected in Chlorella sp. In conclusion, the results confirm that both the irradiance and growth phase influenced the VOC profile of A. platensis and Chlorella sp. as changes in the percentage and types of VOCs present in each species were observed in the cultivation conditions evaluated.
