| 摘 要： | 以D-核糖产生菌枯草芽胞杆菌B2502为出发菌株,经紫外诱变、耐糖选育,得到1株可在D-核糖浓度达6%的肉汤液体培养基中生长的菌株B2502-2。其D-核糖产量提高37%,菌体生长达到对数期的时间缩短3 h,耐糖性比出发菌株提高了50%。

| Abstract: | Bacillus subtilis B2502 was used as starting strain and mutated by UV irradiation and high D-ribose concentration culture medium.A higher D-ribose producing strain B2502-2 was obtained.Its D-ribose production increased by 37%,the period it reached to the logarithmic growth stage was shortened 3 hours,and its sugar-resistance increased by 50% as compared with the starting strain. |
