Evaluación del crecimiento de dos especies de microalgas Chaetoceros Gracilis e Isochrysis galbana con dos tipos de fertilizantes agrícolas, en laboratorio

Abstract

In the present study the growth of two species of microalgae Chaetoceros gracilis and Isochrysis galbana, with two types of agricultural fertilizers Stimufol and Complefol, was evaluated in laboratory. Cell density (cells/mL), specific growth rate (divisions/day) and replication rate (day) of each species in the different treatments was determined. The results show significant differences in the treatments used in cell densities and not in the specific growth rate and doubling time in both cultures of microalgae, showing that higher cell densities, specific growth rate and doubling it obtained in the middle Guillard / F2 followed by Stimufol and lower values in Complefol. Agricultural fertilizers may be a suitable alternative for use in the cultivation of microalgae, including Stimufol can reach higher than Complefol fertilizer productions.
