Inhibitory activities of microalgal extracts against Epstein-Barr Virus (EBV) antigen expression in lymphoblastoid cells

The inhibitory activities of microalgal extracts against the expression of three EBV antigens, latent membrane protein (LMP)1, Epstein-Barr nuclear antigen (EBNA)1 and Z Epstein-Barr reactivation activator (ZEBRA) were assessed by immunocytochemistry. The observation that the methanol extracts and their fractions from Ankistrodesmus convolutus, Synechococcus elongatus and Spirulina platensis exhibited inhibitory activity against EBV proteins in three Burkitt?s lymphoma cell lines at concentrations as low as 20 ?g/ml suggests that microalgae could be a potential source of antiviral compounds against EBV.

Preliminary Observations On Phytoplankton At Sacred Palustrine Habitat, Central Gujarat, India

The aim of the present study was to depict the phytoplankton composition of Sacred Palustrine Habitat (SPH), Anand District, Central Gujarat, India. Collections of phytoplankton were carried out at three permanent sampling stations on monthly basis for one year (June 2012 to May 2013). The phytoplankton population was represented by 39 genera and 48 species belongs to family Bacillariophyceae (21 species), followed by Cyanophyceae (7 species), Cholorophyceae (18 species), and Euglenophyceae (2 species). Species such as Ankistrodesmus convolutus Corda, Closteriopsis longissima Lemmermann, Oscillatoria perornata Skuja, Oscillatoria subbrevis Schmidle, Syndrea ulna (Nitzsch) Ehrenberg, were found abundant at all the study sites, while some species were rare 56.25% (n=27).
