title: Asparaginase activity of BCG and its phenotypes in relation to culture phases.
abstract: The asparaginase activity of the Montreal strain of BCG and of 2 of its phenotypes varies with the age of the culture; it starts to increase at the midlog phase of growth, reaches a maximum value near the end of this phase and decreases during the stationary or autolytic phase. However, the variations in this enzyme activity are greater in 2 the phenotypes than in the parental BCG.
