Bioactives from sustainable sources like seaweed offers enormous advantages than land-based biomass due to its natural abundance, rapid growth, and low lignin content. Herein, the marine algal biomass Ulva compressa is used for the extraction of industrially important bioactives, cellulose and Chlorophyll a. Functional transformation of bulk cellulose into cellulose nanocrystals including water dispersible membrane application have been established. Studies on optical absorbance, emission, reactive oxygen scavenging function, redox behavior at the electrode-interface, anti-bacterial property and bioconjugation with alginate beads enabled that Chlorophyll a could be a multifunctional probe for biomedical application. These findings not only provide selective recovery protocols and processing of bioactives from Ulva compressa (U. compressa) biomass but also enable value added product application for the marine phycocolloids in diversified fields.
