Lactic acid is a commodity product with wide industrial application, which can be generated from different raw materials, making it a target of interest for large companies. On the other hand, most organic acids on the market produced via chemical synthesis generates high levels of pollution. That way, the second-generation organic acids is part of this context, moving towards emerging and future-oriented technologies. The aim of this work was to investigate the lactic acid production from organic waste through Simultaneous Saccharification and Fermentation Process by singly L.helveticus; L.coryniformis; L. delbrueckii lactis and L. pentosus. The fermentability tests on non-hydrolyzed media generated excellent production, yield and productivity results for both strains. L. coryniformis produced 25.26g/L of lactic acid, with a productivity of 1.05 g/L.h and a yield of 51%, while L. pentosus produced 32.62g/L of lactic acid, with a productivity of 1.36 g/L.h and a yield of 60%.
