Producción sostenible de spirulina spp.: impacto del enriquecimiento con humus sobre el rendimiento y valor nutricional a escala semiindustrial

Abstract

This study evaluated the effect of adding humus to the standard culture medium on the biomass production of Spirulina spp. The main objective was to determine whether supplementation with humus could enhance the yield and quality of the biomass compared to the standard medium.

A comparative experiment was set up, cultivating Spirulina spp. in two media: the conventional standard medium and the same medium enriched with a specific concentration of humus. Variables such as growth rate, cell concentration (cells.mL⁻¹), biomass concentration (g.L⁻¹), protein content, and pigment composition were monitored throughout the cultivation period.

The results revealed that the standard medium supplemented with humus showed a significant increase in growth rate and biomass production compared to the standard medium. Additionally, an increase in protein and antioxidant content was observed in the medium with humus.

In conclusion, the addition of humus to the standard medium proved to be an effective strategy for enhancing both the production and quality of Spirulina spp. biomass. This finding suggests that humus can serve as a valuable supplement in culture media for the commercial production of Spirulina spp., offering benefits in terms of yield, nutritional value, and reduction of costs in medium preparation.
