Isolation and Antioxidant Activity of Methyl Aconitates from Arctic Red Alga Polysiphonia stricta

antioxidant activity of extract from a red alga

Antiherpes virus effect of the red marine alga Polysiphonia denudata.

The water extract from the red marine alga Polysiphonia denudata (Dillwyn) Kutz. from the Bulgarian Black Sea coast selectively inhibited the reproduction of herpes virus type 1 and type 2 in cell cultures (EC50=8.7 to 47.7 mg/ml) as shown by the reduction of virus-induced cytopathic effect and viral infectivity. The virus-inhibitory effect was dose-related, strain-specific and depended on viru...

Correction: Isolation, Purification and Properties of an R-Phycocyanin from the Phycobilisomes of a Marine Red Macroalga Polysiphonia urceolata

Phycobilisomes were prepared from a marine red macroalga Polysiphonia urceolata (P. urceolata) by sucrose step-gradient ultracentrifugation. From the prepared phycobilisomes, an R-phycocyanin was isolated by gel filtration on Sephadex G-150 and then purified by ion exchange chromatography on DEAE-Sepharose Fast Flow and native polyacrylamide gel electrophoresis (PAGE) performed in neutral buffe...
