“…Owing to extensive morphological plasticity and the existence of numerous subspecies and varieties, taxonomy based on morphological characters (eg thallus shape, cell size, number of pyrenoids) is particularly challenging in Ulva and often requires molecular studies for correct taxonomic assignment 59,71–73 . While extensive research has been published on Ulva spp.…”

Green macroalgae (Chlorophyta) currently represent a residual fraction (<1%) of global seaweed biomass production landings. In turn, red (Rhodophyta) and brown (Ochrophyta) macroalgae dominate the remaining percentage of aquaculture production, exceeding 32 million tonnes per annum. However, the industry relies on a relatively low number of species, in which as few as seven macroalgal genera collectively represent the bulk of global production metrics. At present, innovation and increased sustainability of the industry calls for diversification of macroalgal species/strains in aquaculture to counteract potential adverse effects ensuing from genetic impoverishment, decreased resilience to disease and climate change. Despite the dominance of red and brown seaweed regarding production figures, aquaculture of green macroalgae has witnessed an increasing trend in productivity and diversification over the last decades, particularly in Asia, where green seaweed taxa often occupy specific market niches in the food sector. Furthermore, growing interest in green seaweeds in aquaculture has been highlighted for different applications in emerging western markets (eg IMTA, biorefineries, food delicacies), owing to a unique diversity of cytomorphologies, ecophysiological traits, propagation capacities and bioactive compounds featured by this group of macroalgae. Cultivation technologies are relatively well developed, but sustainability assessments are scarce and required to unlock the potential of green seaweeds. Although it is likely that green macroalgae will remain occupying specialised market niches, in which high‐value products are favoured, we argue that aquaculture of chlorophytan taxa presents itself as a compelling option under the current quest for commercial diversification of products and expansion of the sector.

“…However, few reports are available on the purification ability of C. taxifolia. This species is widely distributed in the southern tropical coastal areas of China, especially in relatively calm water areas, with large biomass in some areas [29]. Its biological characteristics and invasion ability have been elaborated in our previous paper [30].…”

The marine benthic green macroalga Caulerpa taxifolia is an invasive seaweed found in Europe, America, and Australia, and it forms into huge algal meadows on shallow seafloors with its stolon and rhizoid systems. It has bloomed along the coast of the South China Sea, causing serious environmental problems. However, its ecological impact has not been well studied. Therefore, this study investigated the changes in concentration of NH4-N and NO2-N in artificial seawater in which C. taxifolia was cultivated under laboratory conditions during the circadian rhythm. Results showed that concentrations of NH4-N and NO2-N decreased with the increase in culture time during the circadian rhythm. In 24 h, the NH4-N-removal efficiency increased during the light period, and the maximum reached 71.4%; that of NO2-N increased with time extension in the dark period, and the maximum reached 9.2%. The absorption of NH4-N and NO2-N by terminal stolon of C. taxifolia was different. NH4-N was absorbed more preferentially than NO2-N. However, there was no obvious correlation between NH4-N and NO2-N absorption. Therefore, the terminal stolon of C. taxifolia can be used to clean up inorganic nitrogen, and showed great application potential in the remediation of eutrophic waters as the algal-bacterial symbiotic system could facilitate NO2-N removal.

“…Ulva spp. withstand the extreme environmental condition of earth ponds and when grown in effluent media, protein content increases (> 40%), resulting in a valuable feed for macroalgivore species with high commercial value [2][3][4][5]. The current market for these algae is limited, but could see growth considering the suitability of Ulva as a biomass energy resource and its application as a raw material for nutraceuticals, biomaterials and sulphated polysaccharides (Ulvan) [3,[5][6][7]).…”

The genus Ulva is one of the most numerous of marine and estuarine genera. Traditionally cultivated for human consumption, since the 1990s Ulva was integrated into land based Integrated Multi-Trophic Aquacultures (IMTA) for biomass production and bioremediation. A proper taxonomic identification is the first critical step in implementing an algal production program. However, Ulva species are difficult to morphological identify due to their phenotypic plasticity. Combined molecular and morphological techniques can lead to better characterization of Ulva sp. This study identifies the Ulva sp. cultivated in earth ponds facing the Ria Formosa Lagoon (South Portugal) as well as green algae growing spontaneously in the ponds. DNA barcoding with the markers ITS (Internal Transcribed Spacer) identified six species, with Ulva flexuosa being the cultivated one. Ulva flexuosa was recorded for the first time in South Portugal. However, taxonomic questions were raised because distinct clades were found for this species using published sequences. The 'lettuce-leaf' morphotype observed is not attributable to any of the marine subspecies of Ulva flexuosa.
