Algae in Water Supplies of the United States,round sources after it is exposed to sunlight. Surface waters invariably are habitats for the growth of algae. The amount of growth may be small or very extensive depending upon the concentration of nutrients, turbidity, temperature, and length of exposure to light.

Algae and Medicine, diagramatic scheme of the interrelationship of algae and plankton. The form our contribution will take is not that of a report of an original laboratory study. Rather it will be a digestion and distillation of what has gone before, as seen from a medical perspective.

Database Systems for Advanced Applicationsnitrogen-deficient one in which the cells have accumulated carotenoids and lipoids— and impressive evidence of it is given by many sets of analytical data for . and other unicellular algae. Nevertheless this variability is often overlooked, especially in biochemical studies on algae, and we are far from a complete understanding of how it occurs.

The macronutrients are used generally as building materials, whereas the micronutrients are commonly metal constituents of enzymes which enter into biological reactions (McElroy and Nason, 1954).
