Abstract:

Four microalgae strains of common use in aquaculture were grown with a standard growth medium and with three others, based on agricultural fertilizers. The diatom Phaeodactylum tricornutum Bohlin and the Chlorophyte Dunaliella sp. grew best in the standard medium, another diatom (Chaetoceros sp.) showed equal growth in all media and the eustigmatophyte Tetraselmis suecica gave better results with the fertilizers.

These results are discussed in terms of the convenience of using cheap growth media for commercial purposes, since the use of tailor-made formulations for each species increases the workload of the operators and the probability of human errors.
