Overview

Methodological study demonstrates simplified mid-infrared monitoring of glucose and citramalic acid in continuous E. coli fermentations, indicating accessible real-time bioprocess control.

Key Points

Develop and validate an accessible mid-infrared spectroscopy chemometric platform to monitor nutrient consumption and product formation in continuous bioprocesses.
Designed a streamlined workflow integrating baseline correction, optimal wavenumber selection, and area-under-the-curve (AUC) correlation.
Calibrated and tested spectral models using pure solutions, synthetic mixtures, and continuous Escherichia coli fermentation broths.
Benchmarked the simplified AUC approach against partial least squares (PLS) chemometrics and reference high-performance liquid chromatography (HPLC) measurements.
Continuous culture broths generated the most robust calibration datasets compared to pure solutions and synthetic mixtures.
The baseline/AUC method achieved a mean absolute error of ~0.65 g L⁻¹, delivering fast and reliable predictions aligned with reference HPLC data.
