FIG. 4.

Concentration of galactarate (A and C) and d-galacturonate (B and D) in flask cultures of H. jecorina QM6a Δgar1 udh (squares) and QM6a Δgar1 (circles) (A and B) or A. niger ATCC 1015 ΔgaaA udh (squares) and ΔgaaA (circles) (C and D) maintained at 200 rpm 30°C. Cultures were inoculated with 1.8 to 2.4 g of mycelia liter−1. Mycelia were incubated in 17 g of d-galacturonate liter−1 (pH 5.0; solid symbols) or 17 g of d-galacturonate liter−1 and 2 g of d-glucose liter−1 in modified Vogel's medium (pH 5.0; open symbols). Error bars represent ± the standard error of the mean for three replicate cultures of H. jecorina QM6a Δgar1 udh and three independent transformants of A. niger ATCC 1015 ΔgaaA udh. Single cultures were used for the control strains.
