| Popis: | Growth and fatty acid composition of Isochrysis galbana ALII-4 in batch and semicontinuous outdoor culture in a closed tubular photobioreactor are reported. Specific growth rate at the exponential phase was 0.38 d −1 , higher than that obtained in previous indoor experiments. At biomass concentration above 2 g l −1 net biomass productivity obtained in three successive semicontinuous cultures was 0.32 g l −1 d −1 . A daily cyclic variation in the fatty acid profile was observed. From morning to afternoon, 14:0, 16:0 and 16:1 n 7 content increased, although it decreased during darkness renewing the cycle again with daylight. On the other hand, no daily variation was observed in polyunsaturated fatty acid content. The EPA generation rate during linear growth, with an average content of 2.56%, was 8.2 mg l −1 d −1 . The present study was conducted uninterruptedly in February and March, 1994, in Almeria, Spain (latitude 36° 50′ N, longitude 2° 27′ W). |
