An effective bio-inspired synthesis of platinum nanoparticles using Caulerpa sertularioides and investigating their antibacterial and antioxidant activities

Bioprocess and Biosystems Engineering, 2022
In this study, we report the synthesis of platinum nanoparticles (Cs-PtNPs) using an aqueous extract of Caulerpa sertularioides as a reducing agent. Cs-PtNPs were characterized by UV-Vis spectroscopy, fourier transform infrared (FT-IR) spectroscopy, X-ray diffraction (XRD), field emission electron microscopy (FE-SEM), energy-dispersive X-ray ...

Osteogenic activity of non-genotoxic sulfated polysaccharides from the green seaweed Caulerpa sertularioides

Algal Research, 2019
Abstract Biocompatibility is a requirement for new molecules with potential applications in bone regeneration. Molecules with such potential applications in regenerative medicine include sulfated polysaccharides (SPs) isolated from seaweed. In this study, we evaluated the cytotoxicity and genotoxicity of SPs extracted from the green seaweed, Caulerpa

Amendment of Caulerpa sertularioides marine alga with sulfur-containing materials to accelerate Cu removal from aqueous media

Environmental Science and Pollution Research, 2018
This study reports a new approach of alga amendment in a live mode. The Caulerpa sertularioides alga was modified with sulfur-containing materials of methionine (C5H11NO2S) and sodium sulfate (Na2SO4) to more concentrate the sulfur content of the yielded biomass (adsorbent). The simple and amended C.

Spatial refuges and associational defenses promote harmful blooms of the alga Caulerpa sertularioides onto coral reefs

Oecologia, 2010
Extreme population fluctuations, or outbreaks, are driven by interacting processes that are often more complex than isolated changes in consumer or resource control. Blooms of the macroalga Caulerpa sertularioides in the eastern tropical Pacific overgrew and killed reef-building corals, with blooms onto reefs corresponding to cool La Niña phases of ...
