The present invention provides a high production method of prenyl alcohol, which
comprises culturing prenyl alcohol-producing cells in a medium with an increased
sugar content in the presence of at least one member selected from the group consisting
of a surfactant, a fat or oil, and a terpene to produce and accumulate prenyl alcohol
in the cells; allowing the accumulated prenyl alcohol to be secreted from the cells;
and then collecting prenyl alcohol. The present invention enables prenyl alcohol
to be highly produced in and effectively secreted from prenyl alcohol-producing
cells by culturing the cells in a medium with an increased sugar content in the
presence of at least one member selected from the group consisting of a surfactant,
a fat or oil, and a terpene.
