Description
Summary:This study was conducted to evaluate the biochemical and nutritional characteristics of naturally occurring estuarine macroalgae in the Patos Lagoon (Rio Grande, Brazil). The study of these macroalgae, dominated by Ulva and Cladophora species, contributes to current research on the potential utilization of green tide-forming algae. Although high levels of carotenoids (378 ± 0.02 µg g −1 ) and antioxidant activity (75.0% for DPPH) were found in the naturally occurring macroalgae, these macroalgae cannot be used in the food industry due to the presence of toxic levels of arsenic (exceeding the thresholds of both French and Brazilian legislation for food). Regarding the potential of the studied macroalgae as a biofuel source, the low lipid and very high carbohydrate contents suggest a possible use in the fermentation of ethanol, butanol, or methane.
