Bacillus subtilis TX2(Xan~-)being used as the donor,Bacillus subtilis TSA19(Ade~-+His~-+8-AG~r+6-MP~r +SG~r) as the recipient, with the method of transformation, a stable higher inosine-productivity transformant TSXB29 was obtained successfully.

• 以枯草杆菌（Bacillussubtilis）TX2（遗传标记Xan~－）为供体，以枯草杆菌TSA19（遗传标记Ade~－＋His~－＋8－AG~r＋6－MP~r＋SG~r）为受体，利用转化法成功地获得肌苷产量高、遗传稳定性好的目的转化子TSXB29。
