inoculum 1.6 g/l;
The graphical representation of the Dose-response relationship shows that at concentrations of 2500, 5000 and 10000 mg/l none dose-response dependency.
Because of the almost parallel curve becomes the "concentration axis" assumed that up to the concentration of 5000 mg/l safe and at a concentration of 10000 mg/l probably no inhibition has occurred.
Inokulum 1.6 g/l; Die grafische Darstellung der
Dosis–Wirkungs–Beziehung zeigt, daß es bei Konzentrationen
von 2500, 5000 und 10000 mg/l keine
Dosis–Wirkungs–Abhängigkeit gibt. Aufgrund des nahezu
parallelen Kurvenverlaufs zur "Konzentrationsachse" wird
davon ausgegangen, dass bis zur Konzentration von 5000 mg/l
sicher und bei einer Konzentration von 10000 mg/l
wahrscheinlich keine Hemmung eingetreten ist.
