    Abstract: The present invention concerns a method for genetically transforming a Bifidobacterium strain comprising a step of methylation of a shuttle vector in an E. coli or a Gram-positive bacterium strain by two type II DNA methyltransferases from a Bifidobacterium: a methyltransferase enzyme that methylates the adenine base at position 4 of the nucleotide sequence RTCAGG and a methyltransferase enzyme that methylates the cytosine base at position 4 of the nucleotide sequence GGWCC. The present invention also concerns genetic tools and culture media useful for carrying out said method.

    Abstract translation: 本发明涉及用于遗传转化双歧杆菌菌株的方法,其包括通过来自双歧杆菌的两种II型DNA甲基转移酶在大肠杆菌或革兰氏阳性菌株中甲基化穿梭载体的步骤:使腺嘌呤甲基化的甲基转移酶 核苷酸序列RTCAGG的第4位的碱基和甲基化核苷酸序列GGWCC的第4位的胞嘧啶碱基的甲基转移酶。 本发明还涉及可用于实施所述方法的遗传工具和培养基。
