The influence of different pH on the electrophoretic behaviour of Saccharomyces cerevisiae modified by calcium ions
Abstract The effect of a different pH on Saccharomyces cerevisiae cells modified with calcium ions was investigated by the capillary zone electrophoresis technique. For the identification of the wild strain of S. cerevisiae, the ribosomal nucleic acid sequencing and internal transcribed spacer seque...
