Note on the technique of making bacteria-free cultures of marine diatoms.
There is a great demand for algal cultures in studying morphology, cytology, ecology, cellular pathology and physiology, identification of species, and biotic interaction, and also in feeding small animals in culture for various studies. It is hoped that the following note may be of some use to those who want to start making pure cultures of marine. phytoplankton organisms. Bacteria-free cultur...
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. Hence it was decided to repeat the work on a cultu...
متن کاملSynthesis of Organic Nitrogen and Chlorophyll by Nitzschia Closterium
When cells of Chlorella are grown in a medium containing a limiting quantity of nitrate or ammonia as nitrogen source, photosynthesis and cell division continue after all the available nitrogen in the medium has been abstracted by the growing plants. The cells become nitrogen-deficient. When kept in darkness with added nitrate these nitrogen-deficient cells synthesize a considerable quantity of...
متن کاملFatty Acid Profile and Hydrocarbon Characterization of Nitzschia Closterium (w.sm.)
Lipid productivity is a critical variable for evaluating algal species for biodiesel production. The pennate diatom Nitzschia closterium (W. Sm.) isolated from the local water body of Madurai was cultivated in four different media (WCg, Csi, F/2 and Diatom medium) and screened for the presence of neutral lipid content using Nile red fluorescent dye. The relative abundance of lipid content was e...
متن کاملCopper and zinc tolerance of two tropical microalgae after copper acclimation.
Current toxicity tests with microalgae are often criticized as being overly sensitive to metals because algae are cultured in metal-deficient media. If such bioassays overestimate copper toxicity in surface waters, the relevance of water quality guidelines derived from these tests is questionable. In this study, the effect of acclimation to copper at environmentally relevant concentrations, on ...
