3. Results and Discussion
Y. lipolytica DSM 3286 was cultivated in different media
containing various plant oils as the sole carbon source. Various
mineral and organic nitrogen sources were also tested
for their capacity to support the production of metabolites
(lipase, CA and ICA) and biomass by this strain. Effect
of plant oils and nitrogen sources upon the biochemical
behavior and metabolites production of Y. lipolytica DSM
3286 was investigated by measuring biomass, lipase activity,
CA and ICA concentration at various time points within a
period of 7 days (Figure 1). For all media, the maximum
lipase activity was occurred 48 hours after inoculation and
the high level production of organic acids was determined
after 72 hours (Figure 1).
