摘要: This study evaluated the use of vinasse as a substrate for microbial biomass production and its disposal impact on environment. After grown in vinasse, (SCP) two Saccharomyces cerevisiae strains, CCMA 0137 0188, showed high levels essential amino acids (3.78%), varying chemical elements, low nucleic acid content (2.38%), i. e, good characteristics to food supplemements. Following biological treatment, spent biochemical oxygen demand (BOD) (COD) decreased 51.56 29.29%, respectively. Cultivation with S. cerevisiae significantly reduced short term phytotoxicity toxicity soil microbiota vinasse.
