Method for determining the specific growth rate of a distinct cell population within a non-homogeneous system

摘要

The present invention provides a method for measuring the specific rate of ribosome synthesis for a distinct cell population, such as a distinct microbial population. For an actively growing (or non-growing) culture, the specific rate of ribosome synthesis is identical to the specific growth rate of the culture. With the method of the invention, researchers will be able to measure the specific growth rate of distinct cell populations in mixed cultures, such as biological reactor systems or environmental samples. In addition, the method of the invention provides the ability to identify members of a distinct cell population that are rapidly growing.
