WebThe optimal conditions of salt concentration, pH, and temperature of growth were found to be 0.3 M NaCl, 7.1, 26 °C and 0.6 M KCl, 5.6, 25°C, respectively. Under these conditions, a maximum specific growth rate of 0.41 and 0.5 h−1 was observed in medium containing NaCl and KCl, respectively. WebA simplified model of cell metabolism, consisting of a series of linked reversible enzymatic reactions dependent on the concentration of a single external substrate has been developed. The general mathematical solution for this system of reactions is presented.
