| The feasibility was tested of maintaining long-term semi-continuous or continuous cultures of marine planktonic algae such as <i>Chlorella saccharophila</i> (Krüger) Migula and also algae developing naturally in enriched seawater and which could be suited as food organisms. Diluted aerated swine manure was used as the sole nutrient source for the algae. About 5 liter aerated swine manure per square meter per day x dilution rate per day seemed to satisfy the need of the culture. In view of a possible utilization of thermal effluents, a comparison was made between algal growth in heated and unheated cultures. The experiments were carried out in 250 liter tanks outdoor, equipped with airlift pump. Almost independent of temperature, the algal dry... |

| Since turbulence is an important factor for the growth of microscopic algae, the effect of mixing intensity and mixing time, has been assessed by means of air-lift pumps as an alternative technology for the agitation of algal cultures. Batch culture experiments in enriched sea water were carried out indoors with <i>Chlorella</i> in 100 liter tanks and outdoors with natural phytoplankton populations in 70 m³ tanks. The respective culturing depths in these tanks were 25 and 180 cm. The role of the mixing was also evaluated against that of the pH regulation of the cultures. Mixing with air-lift pumps increased the algal growth rate significantly in comparison to non-agitated cultures. The yields were also much higher (up to 30%) in mixed than in... |
