The transporting processes were affected by the presence/absence of ionophores (calcimysin, nisin, etc) and by the presence/absence of selected low molecular weight organic acids (LMWOAs) (oxalic, malic or citric acid) at different pH values, which are present in the rhizosphere. The model supported phospholipid membranes were prepared in pores of the polycarbonate membrane. Electrochemical impendance spectroscopy has been used to monitor the formation and stability of phospholipid membrane, whereas voltammetric methods were used for detection of species, which are transferred across the membrane. The structure of transported complexes has been investigated using electrospray ionization mass spectrometry. Workplace J.
