Abstract

We report the possibility of an economic cultivation of the marine microalga Tetraselmis suecica, using different mixtures of a common garden fertilizer, soil extract, micronutrients and vitamins. Maximum cellular densities were obtained with a nitrogen concentration of 14 μg/ml and maximum protein concentrations were obtained with 28 μg N/ml, in all cases. The mixture of fertilizer + soil extract + micronutrients gave the best results for obtaining maximum cellular densities and protein concentrations per ml of culture. An economic evaluation showed a maximum of 2770 g of microalgal protein/dollar and 210 × 1012 microalgal cells/dollar with the mixture of the fertilizer and soil extract.
