    摘要： A process for the production of glycerol and proteinous substances of nutritive value which comprises cultivating algae of the Dunaliella species in a nutrient medium containing the mineral requirements of growth of the algae, said nutrient medium having a sodium chloride content of at least 1.5 M, the cultivation being effected while an adequate supply of carbon dioxide is provided and continued until a maximum concentration of algae is obtained, and continuing the cultivation of the algae in a nutrient medium having a content of sodium chloride of at least 3 M, cultivating the algae in this second nutrient medium until a high glycerol content is established, harvesting the algae, recovering from same the glycerol, and recovering the residue having a high protein content.

    摘要： Porphyridium cruentum is cultured in an enriched seawater medium using a high initial cell concentration until the productivity of polysaccharide production by the alga is maximized. The whole culture is then extracted by making the culture strongly alkaline, and heat treating it. The culture is cooled, acidified and the polysaccharide precipitated by addition of a water-miscible organic solvent such as ethanol. Very high yields of polysaccharide are obtained, in excess of 4.5 grams per liter of culture.

    摘要： A method of producing an algal turf for use as a scrubber of carbon dioxide, nutrients and pollutants as well as biomass production is disclosed. A growing surface for spores or benthic microalgae is provided on a water surface. The growing surface is subjected to periodic water surge action to promote metabolite cellular-ambient water exchange and light is provided, natural or artificial to promote growth. The growing turf is harvested before being overgrown by larger macroalgae.
