  • Title: [Dynamics of the formation of extracellular protease and the ATP pool in a thermophilic strain of Bacillus brevis].
    Author: Tsaplina IA, Egorova LA, Sotnikov GG.
    Journal: Mikrobiologiia; 1975; 44(2):241-4. PubMed ID: 1226137.
    Abstract:
    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.
