     the effect of li+ ions as a transformation inducing agent on the yeast cell wall has been studied. twosaccharomyces cerevisiae strains, p63-dc5 with a native cell wall, and strain xcy42-30d(mnn1) which contains structural changes in the mannan-protein complex, were used. fourier transform infrared (ft-ir) spectroscopy has been used for the characterization of the yeast strains and for determination of the effect of lithium cations on the cell wall. a comparison of the carbohydrate absorption band positions in the 970–1185 cm−1 range, of na+ and li+ treated yeast cells has been estimated. absorption band positions of the cell wall carbohydrates of p63-dc5 were not influenced by the studied ions. on the contrary, the treatment of xcy42-30d(mnn1) cells with li+ ions shifted glucan band positions, implying that the cell wall structure of strain xcy42-30d(mnn1) is more sensitive to li+ ion treatment.
