Resumen del producto

During the distillation of ethanol, vinasse is the main byproduct reaching about 90% of the volume of fermentation, and their disposal is a serious environmental problem. The aim of this study was to evaluate the vinasse as a substrate to produce different strains of probiotics for aquaculture and biomass of Bacillus thuringiensis and Spirulina maxima. Medium culture formulated with 25, 50, 75 and 100% of vinasse, and the same treatments supplement with molasses were utilized from bacteria. Spirulina was cultured in Jourdan medium supplement with 5, 10 and 20% of vinasse. All experiments were carried out by triplicate. The medium cultures formulated with 25% and 50% of vinasse were optimal for the bacteria growth. For B. thuringensis at 24 h of growing the yield was similar to control medium (TSA). The same results were obtained in the treatments supplement with molasses. In the case of Spirulina, the supplement of vinasse in the medium culture allows a better development of the blue-green algae than only use the Jourdan medium. The alternatives developed in this work will add value to the waste from the production of bioethanol and generate additional economic contribution for the use of a subproduct.
