Heterofermentative gram-positive bacteria are believed to metabolize sugars exclusively via the pentose phosphoketolase pathway following uptake via sugar:cation symport. Here we show that anaerobic growth of one such bacterium, Lactobacillus brevis, in the presence of fructose induces the synthesis of a phosphotransferase system and glycolytic enzymes that allow fructose to be metabolized via the Embden-Meyerhof pathway.
据信,异型发酵革兰氏阳性菌在通过糖:阳离子同向转运摄取糖之后,仅通过戊糖磷酸酮醇酶途径代谢糖类。在此我们表明,一种这样的细菌——短乳杆菌,在果糖存在的情况下厌氧生长时,会诱导磷酸转移酶系统和糖酵解酶的合成,从而使果糖能够通过糖酵解途径进行代谢。
