Linoleic acid hydroperoxide (HPOD), substrate of hydroperoxide lyase, an enzyme of the
lipoxygenase pathway, can be transformed into many aromatic compounds, the so-called
“green notes”. The presence of linoleic acid hydroperoxide in the culture medium of
Yarrowia lipolytica, the yeast expressing the cloned hydroperoxide lyase of green bell
