Comparative analysis of fatty acid profiles through transesterification in macroalgae from Gulf of Mannar reveal Ulva lactuca for potent edible oil synthesis

Selective macroalgae comprising green algae (Ulva lactuca), brown (Padina gymnosphora, Sargassam wightii, Turbinaria ornate) and red (Gracilaria corticata, Halimeda macrolopa, Halymenia dilatata, Gracilaria crassa) were collected from Gulf of Mannar, India. Taxonomic molecular identification affirmed the identity microalgal species. Free fatty acids Fatty Acid Methyl Ester (FAME) synthesis by transesterification was assessed for cataloguing edible oil source various collected. Lipid components extracted employing solvents namely, Hexane, Chloroform: methanol (2:1), hexane (1:1), (1:2) Dichloromethane: (2:1). The effects different based on Soxhlet extraction preceded GC-MS utilized lipid in macroalgae. Furthermore, vitro anticancer activity against hepatocellular carcinoma cell line, HepG2 indicate 15.6µg/ml concentration showed significant cytotoxicity compared to control. Thus, present report emphasizes optimal role Ulva lactuca as a potential supplement, along with pharmaceutical neutraceutical benefits.
