Mm-wave dielectrometry methods for express-control of intensity development and physiological state of algae

For studying phytoplankton, and also in the cultivation of microscopic algae in culture and industrial production, the regular control of intensity development and physiological state of organisms is indispensable. Conventional microscopic, spectrophotometric and weight methods of the registration of quantitative metrics are durable enough. In this connection of considerable concern is the development of new methods of measurement of the parameters of native cells (for example, differential fluorimetry, hydration degree of cells and state of cells water) which enable one to overcome these difficulties and to receive the new information. In this work the authors carried out analyses of the usage of modern biophysical methods - fluorometry and dielectrometry in the region of free water dispersion of suspensions of native cells for an estimation of intensity of increase of a biomass of microalgas. Both methods, fluorometry and EHF-dielectrometry, have major advantages - they enable one to work with the nonbroken frame of a living cell
