Concise review of the genus Solieria J. Agardh, 1842
Résumé
Solieria spp. (Solieriaceae, Gigartinales, Rhodophyta) can be found in various habitats ranging from the marine environment to low-salinity estuarine environments. Of the commercially exploited carrageenophytes, some of the most abundant belong to the Solieriaceae family as, Kappaphycus, Eucheuma and Solieria. The supply of these seaweeds is ensured by their mastered culture and by large quantities of stranded wild seaweeds which are harvested. Rich in carrageenans, i.e., in linear sulfated galactans, these red macroalgae are widely used for their gelling, thickening, and stabilizing properties in food, cosmetic, or pharmaceutical industries. In addition, Solieria spp. provide scientific potential as a model for the development of cultures in Integrated Multitrophic Aquaculture (IMTA), for innovation in extraction and purification processes and in biorefineries to access to bioactive compounds. The genus Solieria was described using the species Solieria chordalis as the type species in 1842. Today, this species is found in large quantities on the beaches of the western Atlantic just like Solieria filiformis found on the other side of the Ocean on some beaches in Mexico. Due to its abundance, several scientific teams from France and from Mexico study these algae with high potential in nutrition, health and for environmental applications. Eight other species of the genus Solieria have been inventoried, the last one in 2018. Nevertheless, their abundance is lower as well as the number of scientific studies mentioning them. Therefore, in this review, we focus on the biology, ecophysiology, biochemical composition, and applications of Solieria spp. based mainly on the two species widely studied, namely Solieria chordalis and Solieria filiformis.
