Volatile organic compounds from microalgae

Volatile Compounds of Algal Biomass Pyrolysis

“…In agreement with several authors carboxylic acids (Table 6) and amines (Table 7) produced during the pyrolysis of marine algae were identified [11,22,61]. Furthermore, in accordance with many authors aromatic compounds (Table 8) produced by the pyrolysis of microalgae were determined [3,84]. It was proposed that the algae's proteins could be combined with the carbohydrates and react to form aromatic compounds such as phenols, pyrroles and indoles [26].…”

“…The VCs that can be obtained from the algae are a mixture of compounds, and to select the most advantageous volatile compound recovery technique it is necessary to also investigate the location of the target compound within the biochemical system and the volatility of the target molecule, as well as its distribution across the phases under real production conditions [3]. It is advisable to carry out a quantitative analysis of the volatile compounds of interest in large-scale pyrolytic systems, especially those determined with devolatisation within the range of 207.1 and 312.7 • C.…”

“…However, there is worldwide interest in the exploitation of algae based processes and products, essentially due to the diversity of this biomass's chemical composition, as well as its broad spectrum of secondary metabolites. Under the concept of a low-carbon circular bioeconomy, it has been discovered that it is both environmentally and financially desirable to simultaneously combine the algae CO 2 deposits and waste flow phytoremediation, with the synthesis of high value-added products [3,4].…”

“…The objective of this investigation was to study the thermal decomposition of algal biomass by pyrolysis and determine the main volatile metabolites emitted using TG-GC/MS coupling techniques. According to Vieira et al (2020) under the framework of a circular economy all of the biomass fractions must be valued in order to make its use competitive [3]. Therefore, studying the VCs will promote the exploitation of the compounds offered by algal biomasses under the concept of biorefinery.…”
