Dry mycelium of Rhizopus delemar MIM catalyzed the formation of geranyl acetate using 110 mM geraniol and acetic acid at 55 degrees C in heptane to give 11.9 g/l (55% molar conversion). Geranyl acetate was produced at 72.5-75 g/l after 10 days by semi-continuous addition of the substrates. Rhizopus delemar also catalyzed the direct acetylation of different primary alcohols with molar conversions ranging from 65 to 98%.
