From: The effects of external Mn2+ concentration on hyphal morphology and citric acid production are mediated primarily by the NRAMP-family transporter DmtA in Aspergillus niger

Growth kinetics of dmtA mutants and wild type on Mn2+-deficient- and Mn2+-sufficient media. Biomass formation was monitored during the same controlled batch cultivations as shown in Fig. 5. a The growth of the investigated strains on a medium with Mn2+ deficiency (5 µg L−1); b cultivations with sufficient Mn2+ (100 µg L−1). The investigated strains are ∆dmtA (■), dmtAOE (▲) and NRRL 2270 (). Fermentations were carried out in triplicate, starting from conidiospore suspensions. Standard deviations are indicated with vertical bars for each determined biomass concentration (occasionally for strain ∆dmtA, the bar is smaller than the symbol ■)
