Enzymatic-enhanced production of gaharu oil : effects of enzyme loading and duration time

Gaharu, a resinous wood that occurs in trees is belong to Aquilaria genus. It contains more than 12 chemical components that can be extracted that produce aromatic smells. To enhance oil availability and extractability, the effect of enzyme to substrate ratio and pretreatment time were studied. Ther...
