摘要
By dielectric spectroscopy and specific microbiological techniques have been studied the development (cell multiplication) of Saccharomyces cerevisiae and Aspergillus niger growing and multiplication - both on culture media with sucrose and on those with starch. The experimental results have been revealed that the biochemical processes of the studied biomasses have significant changes in certain frequencies in the range 1 - 160Hz, characteristic of the different species/metabolized carbon source, respectively species/ metabolized carbon source/ development phase. It has also been found that in the case of Saccharomyces cerevisiae, the electric field of 50 Hz up to 20V/cm reduces the length of the LAG time and increases the growth rate of intensive increasing phase. Cultures of Aspergillus niger on culture medium with sucrose are stimulated (increasing the spores production by approx. 50% and reducing the maturity time) of 50Hz signals up to 15V/cm. Electric fields higher than 30 V/cm in all media and investigated cultures carry on to the growth reduction / multiplication - up to a complete inhibition of growth at approx. 50V/cm
