    On-Line Monitoring of Biopolymer Content in Bacterial Cells Using Radio-Frequency Impedance

  • Original language description

    This paper describes the implementation of a radio-frequency (RF) impedance-based sensor for on-line monitoring of a biopolymer - medium chain length poly(3-hydroxyalkanoates) (mcl-PHAs, shortly PHA) production process by the Pseudomonas putida KT2442 strain with emphasis on on-line in-situ monitoring of PHA content in bacterial cells. First, motivation for the application of the commercially available RF impedance-based sensor technology is presented. Subsequently, experimental results obtained from fed-batch cultivations of the Pseudomonas putida KT2442 strain are presented and discussed, and a novel scheme for on-line estimation of the PHA content in bacterial cells under the conditions of aerated cultivations combining the capacitance and offgas composition measurements is proposed.
