LEEE Algal Cultures, Analogues of Blooms and Applications Despite some differences, several similarities exist between the data obtained on blooms and cultures. It is to be noted that utility of algal cultures in tropics is mostly limited mariculture and to species isolated elsewhere but not native to their seas. However, most of the cultures are isolated from temperate seas and very few from other regions. Algal cultures are being used as excellent experimental materials to model growth, nutrient kinetics, physiological ecology, pollution research, phycotoxin research, remote sensing and climatic studies. In general, principles of terrestrial plant physiology and biochemistry have been extended to study the physiological ecology of marine micro algae. New techniques have been developed in recent years and rapid advances have been made relating measurements of primary organic production of marine micro algae to their photosynthetic pigments, evident from the plethora of papers and reviews published.
Four examples that involve marine micro algae may be cited: Discovery of photosynthetic picoplankton, UV light and climate, Geoengineering and climate and genetic engineering. Due to the development of tracer carbon-14 technique in 1952, interest in studying marine micro algal cultures has been growing rapidly and many unexpected and exciting discoveries have already emerged. Although studies on natural assemblages of marine phytoplankton and laboratory cultured algae were initiated about the same time (1893), unlike the former, culture studies did not progress till the 1960s as rapidly as one would have wished. To obtain a steady supply of algae for biochemical and physiological experimentation, it soon became necessary to culture the algae under defined laboratory conditions. The spatial and temporal variations of algae are enormous. Their diversity in taxonomy, morphology, size, and nutritional requirements continue to fascinate biological oceanographers. Marine phytoplankters, the free-floating photosynthetic life, play a crucial role in the production of oxygen and in food web dynamics in the seas.
