An apparatus for carrying out algae intensive-cultivation while conducting an environmental control most suitable for growth of algae in an artificial environment including dissolved gas, light, temperature, nutrient source and sanitary atmosphere; and a method of intensive cultivation therewith. There is provided an apparatus comprising water tank (1) for cultivating unialgae as seedling; gas dissolution diffusion units (3-a, 3-b) for achieving dissolution of a gas in a culture water of the water tank; light irradiation units (10, 11) for irradiating the water tank with light whose wavelength and illuminance are controlled; temperature control unit (20) for controlling the temperature of the culture water of the water tank so as to fall within a given range; nutrient salts adding unit (17) for adding to the water tank a nutrient liquid containing an essential nutrient source vital to the growth of algae; purification unit (12) for carrying out bacterial eradication and filtration of the culture water of the water tank; and meters for control of the above units.
An apparatus for forced culture of algae comprising a water tank in which filaments, sporophytes or gametophytes of algae are cultured as algal seeds;
A method for forced culture of algae in a water tank (1) using filaments, sporophytes or gametophytes of algae as algal seeds, comprising a step for dissolving gas in the culture water in said tank, a step for irradiating said water tank with light from a light source, whose light wavelength, light-quality balance and illuminance of blue, red and green are controlled, a step for controlling the temperature of said culture water within a certain range, a step for adding to said cultured water nutrient liquid containing essential nutrients that are indispensable for the growth of algae, and a step for purifying said culture water.
