• Abstract:

  The microbiological control of the industrial production process for obtaining bioethanol has always been a challenge because it is a process involving producer microorganisms (selected yeast) and invaders (contaminants), where invaders must be controlled so that this Control does not interfere with the action. of the producers. The uncontrolled presence of contaminants can make production unfeasible due to competition for raw material in addition to the production of inhibitory substances, changes in the ideal conditions of the process, consumption of the product, among other situations. In this sense, bacterial contaminants isolated from the material of the yeast treatment vat from three different production units in the region of Jaboticabal and also from a fermentation process carried out at Fatec Jaboticabal were tested separately and together for sensitivity to extract of Myrcia bella obtained by aqueous and hydroalcoholic extraction. It was possible to verify that the isolates from fermentation processes were sensitive, and it is important to continue the study to evaluate the use during the fermentation process as a potential way of using this species in the microbiological control of the process to optimize the production of bioethanol.
