Fig. 3From: N,N,N′,N′-tetrakis(2-pyridylmethyl)ethylenediamine, a zinc chelator, inhibits biofilm and hyphal formation in Trichosporon asahiiEffect of N,N,N′,N′-tetrakis(2-pyridylmethyl)ethylenediamine (TPEN) and zinc on morphological transitions in T. asahii T. asahii was cultured in RPMI-plus-MOPS medium containing TPEN, zinc, or TPEN plus zinc, at 37 °C. Controls (no TPEN, no ZnSO4) included the same amount of each solvent. Cells were observed under a light microscope after 48 h incubationBack to article page
