Fig. 6From: Improving E. coli growth performance by manipulating small RNA expression(Taken from [90])Effects of dissolved oxygen shift on growth of a E. coli AB1157 and b SOD deficient mutant. The arrows indicate when dO2 was increased from 30 to 300%. The 30% dO2 reference culture (circle) in (a) parental strain and (diamond) in (b) sodA−sodB− strainBack to article page
