The ability to ferment the trisaccharide raffinose was linked with the presence of plasmid DNA in three strains of Pediococcus pentosaceus. Parental strains showed associated inducible alpha-galactosidase and sucrose hydrolase activities when grown in alpha-galactosides and sucrose, respectively. Derivative strains of PPE1.0, PPE2.0, and PPE5.0, which had lost 30-, 28-, and 23-megadalton plasmids, respectively, had no alpha-galactosidase or sucrose hydrolase activity.
能够发酵三糖棉子糖与三株戊糖片球菌（Pediococcus pentosaceus）中质粒 DNA 的存在有关。当在 α-半乳糖苷和蔗糖中生长时，亲本菌株表现出相关的诱导 α-半乳糖苷酶和蔗糖水解酶活性。分别失去 30、28 和 23 兆道尔顿质粒的 PPE1.0、PPE2.0 和 PPE5.0 衍生菌株均没有 α-半乳糖苷酶或蔗糖水解酶活性。
