Canonical Analysis Technique as an Approach to Determine Optimal Conditions for Lactic Acid Production by Lactobacillus helveticus ATCC 15009

Figure 2

Response surfaces for the production of lactic acid as a function of the variables: (a) temperature and yeast extract concentration; (b) lactose concentration and pH; (c) temperature and pH; (d) yeast extract concentration and pH. For each surface, the other variables are in the center point.
