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%。Bacillus subtilis 132502 was used as starting strain and mutated by UV irradiation and high D-ribose eoneentration eulture medium. A higher D-ribose producing strain B2502-2 was obtained. Its D-ribose production increased by 37%, the period it reaehed to the logarithmic growth stage was shortened 3 hours, and its sugar-resistanee inereased by 50% as compared with the starting strain.
