OUTDOOR BUBBLING CULTURE OF SOME UNICELLULAR ALGAE

[摘要] (1) Using a new type of culture ponds ("open bubbling sytem") according to the principle of Gummert et al., various strains of unicellular algae were grown outdoors without artificial regulation of culture temperature. (2) It was found that, with adequate algal strains, an average daily yield of 16-17g/m2-day (maximum 22-28g/m2-day) was obtainable in summer time, and 2-2.8g/m2-day (maximum 3.3g/m2-day) in winter time. The highest and lowest yield were obtained in August and January, respectively.(3) The advantages and disadvantages of the culture method used, as compared with the other methods thus far proposed for outdoor mass-culturing of algae, were discussed in detail.
