        In the study the production of lactic acid from whey goats as main substrate (SLC) was optimized, following 2k experimental design combined with a central composite design and response surface analysis. It was also determined the combined effects of the concentration of three nutrient level (Riboflavin, yeast extract, ammonium sulfate): X1 and temperature (0C): X2 in lactic acid concentration. According with the results there is enough statistical evidence (95% confidence) that showed that the temperature and the concentration of complement and their interaction influence the production of lactic acid obtained by fermenting goat whey. The greatest lactic acid production (23, 68 g / liter) and bacterial growth were gotten with higher concentrations of nutrients and temperature of 42 ° C.
