During the exponential phase, the intracellular lipids allocation in the mixed
species culture growing on all carbon substrates, is large compared to that observed in the
lag phase (Figure 7) as indicated by the fluorescent microscopic observations. When
observed under the optical microscope, blue globules also indicated build up of a lipid
intracellular pool. In the exponential phase, the lipid allocation inside the cells was
observed in the cell walls, and in an intracellular lipid bodies as observed under the
fluorescent microscope. The intracellular lipid content during the exponential phase is
much higher when the substrates were UDA and UDA+PDB than when the fungal
mixture was grown on PDB alone as a sole source o f carbon and energy.
