Resumo
The sustainable development of value-added compounds through a biorefinery approachusing biomass from invasive macroalgae is feasible. Rugulopteryx okamurae, among theinvasive macroalgae, poses a significant threat in the European Union, with the Bay ofCadiz being particularly affected. This rapid proliferation of this brown alga is causingsubstantial issues, including the displacement of native species. To counteract thenegative impacts stemming from the widespread growth of R. okamurae, utilizing itsbiomass for the production of industrially valuable compounds emerges as a promisingstrategy (1). One potential application involves using this alga to generate fermentablecompounds, such as reducing sugars. However, it is important to note that the chemicalcomposition of macroalgae is subject to substantial variations influenced by seasonalchanges.Here, R. okamurae was collected at different seasonal periods and exposed tohydrothermal acid pretreatment. Fibre analysis were performed on both pretreatment andnon-pretreated seaweed and possible differences between the different fractions of itsfibre composition were evaluated
