Absstract of: WO2022269464A1

A method and system for monitoring invasive species in an algal bioreactor utilizes a low resolution Raman spectrometer (LRRS) system and signal processing methods based upon Support Vector Machine (SVM) models. A spectrum preprocessing algorithm transforms LRRS spectra into normalized spectral data vectors. An ex-situ method is used to analyze a calibration set of known samples of a suspension containing a desired biomass, such as spirolina, together with various concentrations of invasive algal or cyanobacterial species. The ex-situ method generates SVM models and their associated SVM support vectors for classification modeling. An in-situ method uses the SVM models to provide an output vector of probability values corresponding to the presence of invasive species in an unknown sample, and optionally to provide an additional output vector of probability values corresponding to concentrations of the invasive species in the unknown sample.
