This work reported on the in vitro antibacterial activity of six selected marine algae (seaweeds) which have been selected and their extracts have been tested as an alternative to commonly used antibiotics. Extracts of six seaweed samples namely Codium decorticatum, Caulerpa scalpelliformis, Gracilaria crassa, Acanthophora spicifera, Sargassum wightii and Turbinaria conoides were collected from...

The active principles of brown alga, Turbinaria conoides (J.Agardh) Kuetz. (Sargassaceae) was extracted with n-hexane, cyclohexane, methanol and ethanol-water (1:1) and investigated for acute toxicity and antipyretic activity. Phytochemical analysis of the extracts revealed the presence of steroids, flavonoids and reducing sugars. Acute toxicity study was performed in Wistar rats after administ...

Silver and gold nanoparticles were synthesized using an aqueous extract of the seaweed Turbinaria conoides and their antibiofilm activity against marine biofilm forming bacteria is reported here. The UV-Vis spectra showed the characteristics SPR absorption band for Ag NPs at 421 and for Au NPs at 538 nm. Further, the synthesized nanoparticles were characterized using FT-IR, XRD, FESEM, EDX, and...

Kappaphycus striatus is one of the most important eucheumatoid species that widely farmed worldwide. In southern Philippines, where initial farm was established, sluggish growth brought about by poor quality planting materials and extensive farming resulting in unproductive farms frequent ice-ice outbreaks have been a hindrance increasing seaweed production. As result, farmers led to applicatio...
