The possibility of a pressure monitoring system by differential pressure sensors to detect contaminant effects on cellular cultures metabolic activity is discussed using Saccharomyces cerevisiae, lymphocyte, and AHH1 cell cultures. Metabolic (aerobic and anaerobic) processes in cells are accompanied by CO(2) production that induces changes in pressure values when cells are cultured in sealed vessels. These values are subsequently converted in voltage units and plotted pressure dynamics versus time. Read More

To investigate the effects of extremely low frequency magnetic fields on ultraviolet radiation (UV) exposed budding yeast, haploid yeast (Saccharomyces cerevisiae) cells of the strain SEy2101a were exposed to 50 Hz sine wave magnetic field (MF) of 120 microT with simultaneous exposure to UV radiation. Most of the UV energy was in the UVB range (280-320 nm). The biologically weighted (CIE action spectrum) dose level for the UV radiation was 175 J/m2. Read More

Fourier Transform InfraRed spectroscopy (FTIR) is an emerging technique in biology. One of the analytical problems inherent with this approach is the extreme variability typical of biological systems. Extrinsic fonts of variations are the growth media and the growth phase of the microbial culture. Read More

We studied action of one-dimensional, two-dimensional and three-dimensional low-frequency oscillating electric and magnetic fields on sugar metabolism in Saccharomyces cerevisiae cell culture. S. cerevisiae cells were grown on a minimal medium containing glucose (10%) as a carbon source and salts (0. Read More
