The dynamics of varying ATP concentration was studied in the cells of the thermophilic strain of Bacillus brevis 224 synthesizing a neutral exoprotease. Some irregularities during the primary and secondary growth of the culture corresponded to the changes in the amount of ATP. A sharp decrease (by a factor of ca. 100) in the level of ATP pool was detected in the bacterial cells after 2.5 hours of their exponential growth; their growth ceased and the synthesis of protease was depressed. A decrease in the rate of the enzyme synthesis coincides with an increase in the concentration of ATP in the cells.
