<Plant waste lipids> after solvent refining process were used as a carbon source for cultivation of <Penicillium roqueforti 18> <Penicillium sp.Z> and <Apiotrichum curvatum> ATCC 20509. Biomass yield varied from 3.8 g d.m./l to 19.9 g d.m./l and lipids yield varied 1.0 g/l to 10.6 g/l. Lipids utilization in medium varied from 15.0% to 85.4%. Process efficiency, and percentage composition of fatty acids of intracellular lipids and grease remaining in the medium depend first of all on medium composition, type of microorganisms used, temperature and time cultivation.
