When microbial destruction is plotted with a semi-logarithmic scale, a straight line is noticed. A ‘shoulder’ is typically noticed firstly in the curve. This decrease death level is attributed to the genetic repair service mechanisms of the cells, e.g. when subjected to very low doses of UV radiation. Bacterial spores have to be ‘activated’ before they're able to germinate and increase out to be prototypical vegetative cells. This phenomenon can also cause a ‘shoulder’ in survival curves. At the conclusion of the survival curve, a ‘tail’ could possibly be noticed, indicating the presence of resistant cells or clumps of cells. Legitimate dormancy is found only in bacterial endospores. Nonetheless, even vegetative organisms can generate a successful state of dormancy as a result of possibly a relatively gradual death fee or development and destroy prices that offset each other.
