The present disclosure is directed to systems and methods for sampling and/or controlling the productivity of a bioreactor. The system and methods can include a vessel capable of providing an environment suitable for containing whole broth that can produce the bioproduct, wherein the whole broth contains media and at least one undissolved species, an automated sampling system, a first analytical instrument, and a control system.

Systems and methods for producing bioproducts

The present disclosure is directed to systems and methods for sampling and/or controlling the productivity of a bioreactor.

Methods and apparatus are disclosed for correcting measurements received by applying a frequency-varying signal with a measuring device (e.g., a permittivity probe) to a population of living cells (e.g., contained in a bioreactor) and correcting measurement divergences using data acquired using an alternate analytical method (e.g., trypan blue exclusion). In one example, a method comprises receiving electrical property data for a first population of cells, the data obtained by applying a first frequency-varying signal to the population with a measuring device, receiving biological property data obtained using an alternate analytical technique, generating at least one value representative of the frequency dependence of the electrical property data, and determining a relationship between the biological property data and the representative value. In some examples, measurements of apoptosis are predicted using the electrical property data.
