The aim of the paper is to determine correlation dependences between values of luminescence intensity of bacteria <em>Photobacterium phosphoreum</em> and factors determining geomagnetic activity.</p><p><strong>Methods</strong><strong>.</strong> The optimum parameters of suspension were determined for research of bioluminescence intensity as a bioindicator of the geomagnetic field state. The monitoring of specific intensity of bacteria luminescence has been carried out for 2 months and it was compared to the daily values of activity of the geomagnetic field in the conditions of Kiev, during the research of bioluminescence. Vari­ation determination of the geomagnetic field was conducted from data of Space Environment Center, NOAA & U.S. Air Force. Description of sun activity was conducted with the use of the "Wolf numbers" and flux of sun radio radiation at a wavelength 10,7 сm.</p><p><strong>Results.</strong> The correlation coefficients of changes of bacteria bioluminescence intensity daily values were calculated and compared to the K-index and Ap-index values, "Wolf numbers", and flux of sun radio radiation. The inverse proportional reliable average correlation was defined <em>R</em> = -0,41 between the values of specific bacterial luminescence and the K-indexes of the geomagnetical field, and with the values of flux of sun radio radiation – reliable directly proportional correlation. It is shown, that at the geomagnetic field variation intensity increase there is reduction of values of bacteria bioluminescence specific intensity.</p><p><strong>Conclusions.</strong> The presence of reliable inverse dependence between K-indexes of geomagnetic field is shown and specific intensity of the <em>P. rhosphoreum</em> luminescence, the correlation coefficient in months with increased geomagnetic activity was <em>R</em> = -0,51. The use of the automated system of the luminescent bacteria luminescence intensity monitoring allows better forecasting in time the manifestations of indignations of the Earth’s magnetic field.</p>}, number={4}, journal={Innovative Biosystems and Bioengineering}, author={Gorgo, Yuriy and Gretsky, Igor and Demydova, Olha}, year={2018}, month={Dec.}, pages={271–277} }
