When microbial destruction is plotted on the semi-logarithmic scale, a straight line is observed. A ‘shoulder’ is usually observed firstly on the curve. This decrease Loss of life amount is attributed to the genetic maintenance mechanisms on the cells, e.g. when subjected to reduced doses of UV radiation. Bacterial spores must be ‘activated’ right before they could germinate and grow out to become prototypical vegetative cells. This phenomenon might also lead to a ‘shoulder’ in survival curves. At the end of the survival curve, a ‘tail’ can be noticed, indicating the presence of resistant cells or clumps of cells. Genuine dormancy is discovered only in bacterial endospores. Nonetheless, even vegetative organisms can deliver a highly effective state of dormancy as a consequence of possibly a relatively sluggish Loss of life rate or growth and kill fees that offset one another.
