Fig. 4From: Bacillus subtilis 5′-nucleotidases with various functions and substrate specificitiesColony formation by B. subtilis strains. Suspensions of strains 168, NON05, and NON06 were streaked on LB plates with (right) or without (left) 1 mM IPTG and incubated overnight at 37 °C. All experiments were repeated more than three times and similar results were observedBack to article page
