Brown algae have the unique ability to produce phlorotannins, which are phenolics with potent antioxidant capacity. These valuable metabolites have numerous applications in medicine, cosmetics, and food industries. Therefore, it is extremely important to develop strategies to continuously produce these compounds without having to constantly harvest seaweeds from the environment. In this work, the possibility of growing Fucus spiralis under artificial conditions by tissue culture techniques was evaluated and optimized. After growing for four months, callus were excited from the original explants and evaluated for phlorotannin content by the FolinCiocalteu method and scavenging potential by the 2,2-diphenyl-2-picrilhidrazil (DPPH) scavenging assay. Phlorotannin content and scavenging potential were compared with wild-collected tissue. Fucus spiralis grown callus exposed to 60 mu mol photons.m(-2).s(-1) presented the highest phlorotannins' content and the highest scavenging potential with 250.02 +/- 7.24 mg phloroglucinol equivalents/g extract and an IC50 of 125.2 (101.3-139.5) mu g/mL, respectively. This research represents the first evaluation of the potential of Fucus spiralis to be cultured under artificial conditions for phlorotannins extraction, opening a new window for further optimization and development of photobioreactors for continuous phlorotannins production.
