Algal Physiology and Large-Scale Outdoor Cultures of Microalgae

摘要: The reliable and efficient production of microalgae in large-scale commercial culture, whether open ponds or closed photobioreactors, requires a good understanding the physiology alga being cultured. Since cultivation is almost always carried out outdoors, algae experience an environment which changes during day, from day-to-day, also seasonally. Key environmental factors are light temperature, use available critical for obtaining maximum productivity. How algal cell metabolism regulated under such conditions important as ability to acclimate changed conditions. Algal productivity formation desired products carotenoids (e.g. β-carotene astaxanthin) long-chain polyunsaturated fatty acids further affected by nutrient sources availability requirements intensive culture need be understood. inorganic carbon either dioxide bicarbonate especially important. Understanding biochemistry enables manipulation optimise metabolite (product). diurnal circadian rhythms may aid optimising maximising yields adjusting timing harvesting.
