A survey for viruses from fresh water that infect a eucaryotic chlorella-like green alga.
Viruses which formed plaques on lawns of a eucaryotic, chlorella-like green alga were detected in 37% of the 35 freshwater samples surveyed. Virus populations, monitored in seven locations, fluctuated both qualitatively and quantitatively over an 8-month period.
متن کاملSynthesis of Vitamin A by a Fresh-water Alga, Chlorella (sp.?).
JAMESON, DRUMMOND and COWARD [1922] showed that a marine diatom, Nitzschia closterium W, Sm., synthesises vitamin A when grown in Miquel's solution or sterilised sea-water in diffused sunlight. This work was, however, open to the criticism that the culture, one supplied by Dr Allen, Plymouth, was not pure, having been found to contain bacteria.

متن کاملBiosorption of cadmium and lead from aqueous solution by fresh water alga Anabaena sphaerica biomass
The present work represents the biosorption of Cd(II) and Pb(II) from aqueous solution onto the biomass of the blue green alga Anabaena sphaerica as a function of pH, biosorbent dosage, contact time, and initial metal ion concentrations. Freundlich, Langmuir, and Dubinin-Radushkevich (D-R) models were applied to describe the biosorption isotherm of both metals by A. sphaerica biomass. The bioso...
