【 摘 要 】

The use of liquid cassava waste (manipueira) as the medium for the biotransformation of citronellol using a Penicillium sp strain was studied. The strain was able to grow in the waste and production of cellular mass reaching 25 g/L over three days of contact of the spores with the medium. Submerged cultures of Penicillium sp grown in manipueira were able to convert the substrate into cis- and trans-rose oxides when the cells were transferred into a mineral medium for the biotransformation experiments. The production of rose oxide increased by more than 2.4 times using this 2 media process as compared to processes using only a manipueira medium (cassava medium). Auto-oxidation products were not detected in the control experiments.
