| Abstract: | An L-isoleucine auxotropy mutant,strain SF28,resistant to sulfaguanidine and rifampin was obtained from Brevibacterium Tianjinese T6～13 by serial treatment with ultraviolet ray.This mutant produces L-proline in shaking flask at 32℃ when fermented for 72 hours,and it can produce 37.8g/L of L-proline on examination of medium composition. |
