Abstract

The exploration of seaweed as a functional sustenance, energy source, and
pharmaceutical and medicinal agent has been encouraged by recent research advance
ments. This study was conducted to assess the biological efficacies of sulfated polysaccha
rides extracted from Caulerpa scalpelliformis, including their antimicrobial, antibiofilm,
antioxidant, and emulsification properties. The antioxidant efficacy of sulfated polysac
charides of C. scalpelliformis was assessed using a variety of standard assays. The results
of these tests showed that the antioxidant activity of these sulfated polysaccharides was
concentration-oriented, and they had higher antioxidant capacity at 1000 μg/mL in all
the assays subjected to the present study. In the case of antibacterial activity, polysaccha
rides exhibited the highest inhibition zone against Pseudomonas aeruginosa (18 mm) and
the lowest against Proteus mirabilis (10 mm). The sulfated polysaccharides exhibited max
imum inhibition on biofilm formation by Bacillus subtilis at the highest concentration
tested (100 μg/mL). Their emulsification index (E24
) was maximum in gingelly oil (270 ±
0.5%). GC-MS analysis showed a total of 19 peaks with their respective compounds.
Additional research is required to assess other biological functions of C. scalpelliformis.
