stationary phase


Also found in: Encyclopedia, Wikipedia.

sta·tion·ar·y phase

1. the period in the course of growth of a bacterial culture during which the multiplication of the organisms becomes gradually less and the bacteria undergoing division are in equilibrium with those dying;
2. referring to the usually solid, nonmobile component in partition chromatography.

stationary phase

a period in the growth of a culture of BACTERIA where the number of CELLS dividing is equal to the number dying. The growth of the bacterial population therefore ceases and the GROWTH CURVE levels off.
