Fig. 3. Effect of stieleriacine A₁ on growth of strain Mal15^T.

a Time-lapse series of untreated Mal15^T cells during the 6.25 h lag-phase (1–5) and after initialisation of cell division and entrance into the exponential phase (6–8). The division as such from budding to daughter cell release required 1.9 h. b The lag phase of Mal15^T cells was significantly shorter (1–5: 5.16 h) once treated with 1.34 µM stieleriacine A₁, while the division as such lasted 1.9 h as well (6–8); (untreated: 6.25 h (a), treated: 5.16 h (b), p = 0.0058). The scale bar is 1 µm.
