Diversified Technologies' New Compound Extraction from Microalgae Utilizes PEF Which Yields a Four-Fold Increase

BEDFORD, Mass., May 20, 2020 /PRNewswire-PRWeb/ -- Diversified Technologies, Inc. (DTI) has introduced a patented process using PEF (pulsed electric field) processing for extracting pigments, proteins, and lipids from microalgae.

DTI's Compound Extraction from Microalgae uses PEF for the low cost extraction of phycoerythrin (PE) and phycocyanin (PC), providing high purity extraction without solvents. When treating lipid extraction from Chlorella vugaris high oil biomass with PEF prior to freeze drying, there was a four-fold increase in extracted lipids with hexane and the same for ethanol, compared to untreated samples.

To test the efficacy of using PEF to extract PE, DTI's treated freshwater- adapted Porphoridium purpurem at field strengths from 0-39 kV/cm and efficiently released the PE without cell disruption. They used a similar approach to extract PC from Spirulina platensis cells, with PC being liberated from cells after treatment with voltages above 10 kV/cm.

DTI's Compound Extraction from Microalgae effort was funded by USDA NIFA Phase II SBIR Grant 2017-33610-27016.
