Immunomodulatory effects and antimicrobial activity of heterofucans from Sargassum filipendula
Journal of Applied Phycology, 2017 Parasitic diseases are a human health problem mainly in low-income areas. The drugs available for the treatment of these diseases are far from satisfactory due to high costs, toxicity, and drug resistance. Sulfated polysaccharides are a complex group of bioactive polymers and can be obtained from seaweeds.

The Growth of Monoraphidium sp. and Scenedesmus sp. Cells in the Presence of Thorium
The Scientific World Journal, Volume 2012, Issue 1, 2012., 2012 Toxicity of thorium by Monoraphidium sp. and Scenedesmus sp. was studied. Microalgal cultures were inoculated in ASM‐1 medium in presence and absence of thorium. Its effect was monitored by direct counting on Fuchs‐Rosenthal chamber and with software. The toxicity of thorium over the species was observed for concentrations over 50.0 mg/L. After 30 days,
