摘要

The possibilities to improve the yields of a mass culture of algae were studied. The effect of the method of stirring and the resultant changes in light-dark intermittency in the cultures were examined. The method of supplying carbon dioxide to the culture was improved. It was shown that it is feasible to precipitate the algae from their medium using polyelectrolytes. It was found that suitability for mass culture can be readily screened by means of simple growth experiments together with photosynthetic measurements. No algal species more promising than Chlorella were found. The solubility of gases in the media was studied and on the strength of these measurements it was predicted and found that in a small closed tank carbon dioxide is absorbed almost quantitatively and oxygen released from the medium. Growth experiments disproved the claimed effect of polyvinyl alcohol on the growth and chlorophyll synthesis of the algae. A new method for determining ethylene diamine tetra-acetic acid is also described. (Author)
