A recent study published in Plant Stress suggests that a bioactive compound in olive mill wastewater may have commercial application in developing biopesticides.

Researchers from the Sapienza University of Rome and the Italian National Agency for New Technologies, Energy and Sustainable Economic Development identified pectin-derived oligogalacturonides with a degree of polymerization between ten and 17 in the olive mill wastewater.

Oligogalacturonides trigger a plant’s immune system via the cell wall, activating defense responses and resistance against some pathogens. The molecules had not previously been separated from olive mill wastewater.
