The interactive effect of combinations of the Fusarium mycotoxins deoxynivalenol (DON), zearalenone (ZEA) and fumonisin B1 (FB1) on growth of brewing yeasts was examined. Yeast growth was assessed by measurement of dry weight or relative growth, cell number, viability and conductance change of the growth medium using direct and indirect methods. The(More)
This work describes a method for the determination of theFusarium mycotoxin moniliformin (MON) in cereals. In addition to the optimization of the clean-up and the HPLC determination the most efficient extraction mode was investigated on natural contaminated samples. The method was validated for maize and wheat using a calibration range from 57 to 2300(More)
AIM To determine the viability of Enterococcus faecalis in infected human root dentine in vitro after exposure to root canal medicaments based on chlorhexidine and octenidine. METHODOLOGY Human root segments (n = 40) were infected with E. faecalis for 8 weeks. Root dentine samples (rd) collected at week 4 served as individual baseline values. At week 8,(More)
