Abstract: Devices, methods, and systems employing a multivariate optical computing sensor comprising a multivariate optical element calibrated to independently measure an electromagnetic spectral pattern of a cultivation characteristic of an algae stain in a cultivating algae water slurry and a detector for receiving output signals indicative of the cultivation characteristic. The cultivation characteristic may include, for example, total organic carbon, total carbohydrate, or fatty acid methyl esters.

Abstract: The present disclosure relates to methods for compositional analysis of algal biomass, specifically weight percent elemental composition. In at least one embodiment, a method for compositional analysis of an algae sample includes flash combusting a first portion of the algae sample to provide a carbon wt %, a hydrogen wt %, and a nitrogen weight %. The method includes pyrolysing a second portion of the algae sample to provide an oxygen wt %. The method includes scanning a third portion of the algae sample using x-ray fluorescence to provide an elemental intensity. The method includes normalizing the elemental intensity using the carbon wt %, the hydrogen wt %, the nitrogen wt %, and/or the oxygen wt %.

Abstract: A method and system for direct quantification of the concentration of biomolecules in algal biomass. The biomolecules include lipids, proteins, and carbohydrates. An algae slurry is cultivated within a cultivation vessel, and algal biomass is harvested therefrom. A portion of biomass is analyzed using solvent-lipid analysis to extract lipids and nuclear magnetic resonance spectroscopy is used to quantify the biomolecular concentration of the biomass.
