Crude sulfated polysaccharides extracted from marine cyanobacterium with evaluation antioxidant and cytotoxic activities.

Background And Objectives: Microalgae have been widely used as a novel source of bioactive substances. These substances exhibit various biological actions including, antioxidant and antitumor effects material. The present work is carried out to evaluate potential applications of cyanobacterium containing mainly polysaccharides.

Antimicrobial screening of silver nanoparticles synthesized by marine cyanobacterium .

Background And Objectives: Nanoparticles are widely used in various fields such as electronics, cosmetics, water purification, biomedical and biotechnology. Biosynthesis of nanoparticles using biological agents have gained much attention in the area of nanotechnology in the last few decades because of cost effective, non-toxic, and eco-friendly. Algae have been used to reduce metal ions and subsequently for the biosynthesis of nanoparticles.
