Abstract

A wild-type strain of Methanobacterium thermoautotrophicum Marburg was transformed by DNA from strains resistant to 5-fluorouracil. Recipient cells were grown without selection on gellan gum (GELRITE) plates with DNA. Drug-resistant cells were recovered by replica plating the resulting colonies onto drug plates. Transformation required high-molecular-weight DNA with appropriate markers and was not observed on agar or in liquid media under a variety of conditions.

摘要

嗜热自养甲烷杆菌马尔堡野生型菌株被来自对5-氟尿嘧啶有抗性的菌株的DNA转化。受体细胞在含有DNA的结冷胶(吉兰糖胶)平板上不进行选择培养。通过将所得菌落影印接种到含药平板上回收耐药细胞。转化需要具有适当标记的高分子量DNA,并且在各种条件下在琼脂或液体培养基中均未观察到转化现象。
