A number of selected fermentative bacteria were surveyed for the presence of the phosphoenolpyruvate:glucose phosphotransferase system, with particular attention to those organisms which ferment glucose by pathways other than the Embden-Meyerhof-Parnas pathway. The phosphoenolpyruvate:glusoe phosphotransferase system was found in all homofermentative lactic acid bacteria tested that ferment glucose via the Embden-Meyerhof-Parnas pathway, but in none of a group of heterofermentative species of Lactobacillus or Leuconostoc, which ferment glucose via the phosphoketolase pathway. A phosphoenolpyruvate:glucose phosphotransferase system was also absent in Zymomonas mobilis, which ferments glucose via an anaerobic Entner-Doudoroff pathway. It thus appears that the phosphotransferase mode of glucose transport is limited to bacteria with the Embden-Meyerhof-Parnas mode of glucose fermentation.
对一些选定的发酵细菌进行了调查，以检测磷酸烯醇丙酮酸：葡萄糖磷酸转移酶系统的存在情况，特别关注那些通过除Embden-Meyerhof-Parnas途径以外的途径发酵葡萄糖的微生物。在所测试的所有通过Embden-Meyerhof-Parnas途径发酵葡萄糖的同型发酵乳酸菌中都发现了磷酸烯醇丙酮酸：葡萄糖磷酸转移酶系统，但在一组通过磷酸酮醇酶途径发酵葡萄糖的异型发酵乳酸杆菌或明串珠菌中均未发现。运动发酵单胞菌也不存在磷酸烯醇丙酮酸：葡萄糖磷酸转移酶系统，该菌通过厌氧的Entner-Doudoroff途径发酵葡萄糖。因此，葡萄糖转运的磷酸转移酶模式似乎仅限于具有Embden-Meyerhof-Parnas葡萄糖发酵模式的细菌。
