The aim of this study was to immobilise Saccharomyces cerevisiae cells on corn stem ground tissue and evaluate the biocatalyst produced for efficiency to perform alcoholic fermentation. The results indicate that corn stem might be an interesting support for yeast cell immobilization, and also a cheap alternative resource of mineral components with possibility of application for improving ethanol productivities. The prepared biocatalyst showed higher fermentation activity compared to free cells. The advantage of the corn ground tissue as yeast cells carrier is high porosity, which facilitates the transmission of substrates and products between carrier and medium.
