Evaluación de la acción de saccharomyces boulardii y bacillus spp en la degradación de materia orgánica en sedimentos de camaroneras.

Abstract

The accumulation of organic matter in shrimp farm sediments can negatively impact water quality and Litopenaeus vannamei production. This study evaluated the ability of Saccharomyces boulardii and Bacillus spp. to degrade organic matter and reduce nitrogenous compounds (NH₄⁺, NO₂⁻, and NO₃⁻) in aquaculture sediments. A completely randomized experiment was designed with four treatments: control, 20 ml of S. boulardii, 20 ml of Bacillus spp., and 40 ml of a combination of both microorganisms. Over 20 days, key physicochemical parameters (temperature and pH) were monitored. The results showed significant differences in organic matter reduction among treatments (p < 0.05), with a decrease of 70.03% in the combined treatment, 69.46% in Bacillus spp., and 66.48% in S. boulardii. Additionally, NH₄⁺ and NO₃⁻ concentrations significantly decreased, while NO₂⁻ levels remained low. It is concluded that the application of these microorganisms is a viable strategy for bioremediation in aquaculture systems, promoting the sustainability of shrimp farming.
