[Glucose metabolism in Clostridium sporogenes and Clostridium sticklandii bacteria]

Clostridium sporogenes 272 has a high rate of glucose fermentation. Its cell-free extract contains all glycolytic enzymes catalysing glucose degradation to pyruvate and shows the phosphoroclastic activity. C. sticklandii CSG has a low rate of glucose fermentation. Hence, the activity of the following enzymes is lower in this organism comparing to C. sporogenes: phosphohexoisomerase (EC 5.3.1.9), phosphofructokinase (EC 2.7.1.11), aldolase (EC 4.1.2.13), triosephosphate isomerase (EC 5.3.1.1) and glyceraldehyde phosphate dehydrogenase (EC 1.2.1.12). Moreover, it is possible that the system of glucose transport into the cell is damaged in C. sticklandii.
