Biochemical process for growing living cells by measuring the amount of nutrient added to the reaction medium

摘要

Disclosed is a process for growing living cellular material in a reaction zone having a membrane in contact with an aqueous medium. The concentration of nutrient in samples from the process is measured using a spectrometric instrument to obtain spectral data characteristic of nutrient components. This spectral data is analyzed using a chi-squared mathematical technique to determine the unknown concentration of nutrient components in said samples. Then the rate at which nutrient is fed to the reaction zone is altered based on the determination of concentration of nutrient components as required to optimize the process.
