Growth of E. coli MG1655 and E. coli ΔkduID under aerobic and anaerobic conditions ^a.

a

Data are expressed as medians and minima versus maxima (aerobic, n = 6; anaerobic, n = 5).

b

Cultures were incubated in M9 minimal medium containing 50 mM galacturonate or glucuronate with or without sucrose.

c,d

Data represent comparisons of the results obtained with E. coli MG1655 versus E. coli ΔkduID that included use of the same medium (Mann-Whitney test; ^c, P<0.05; ^d, P<0.01).
