The main aim of the present work was to study the use of agriculture excess as substrates for dextran and lactic acid production. The fermentations were carried out with the microorganism Leuconostoc mesenteroides B512F in a medium containing cashew apple juice and sucrose. The concentrations of reducing sugar and sucrose were varied according to factorial planning. At the end of the fermentation the dextran, the lactic acid and biomass produced were quantified.The results were analyzed by the surface response analysis methodology. According to the results increasing the sugar level favors dextran and lactic acid production. The use of cashew apple juice as an alternative substrate for dextran and lactic acid production presented technical viability.
