KINETIC PARAMETERS OF GROWTH OF <I>Saccharomyces cerevisiae</I> AFFECTED BY A VARYING MAGNETIC FIELD OF LOW INTENSITY AND HIGH FREQUENCY

In this work, the growth of the Saccharomyces cerevisiae yeast in molasses (virgin honey), is evaluated in the presence of a variable magnetic field (MF) of high frequency and low intensity. The kinetic parameters, such as the maximum specific speed of growth (μmax), the saturation constant (Ks) and...
