Abstract

PURPOSE: The seeds of diatom are inoculated to a culture medium composed of sterialized sea water and nutrient salts and cultured under specific conditions, thus cultivating a large amount of diatom continuously with low energy.
CONSTITUTION: The culture medium composed of sterilized sea water and nutrient salts is poured into a cultivation tank made from a transparent material and controlled to a prescribed temperature with a temperature regulator. The seeds of diatom are inoculated to the culture medium and cultured under irradiation with light emitted from the source fitted in a zone in a distance of 0W20cm from the wall surface of the tank so that the total luminous flux becomes 10W100lm/1l of the volume of the cultivation tank and simultaneous aeration with sterilized air to effect sufficient feed of carbon dioxide gas and sufficient agitation, thus promoting multiplication. When the cell density of diatom reaches 106W108(cell/ml) the cultured diatom is taken out of the culture mixture by 1/5W2/3 volume of the total culture mixture in a certain time interval and at the same time, the fresh culture medium is fed to the culture mixture by the same volume as that taken out.
