Xanthan gum is a polysaccharide commonly used as thickening agent and stabilizer foods. It can be produced using fermentation of the bacteria Xanthomonas campestris. The following plot shown xanthan gum production from sucrose using X. campestris. Answer the following questions using the plot shown below.
