摘要：

An experimental statistical design was used to determine pH and temperature optima for growth and polymer production by Xanthomonas campestris. A pH between 6.0- 7.5 and a temperature between 25-27 degrees C were optimal for growth. While for xanthan production and broth consistency index, the pH and temperature optimal ranges were between 7.0-8.0 and 25-30 degrees C, respectively. At these optimal ranges a cell concentration of 3.2 g litre(-1), polysaccharide concentration of 17.7 g litre(-1) and a consistency index of 100 mPa s(n) was obtained.
