Abstract:

In this study oleaginous microorganisms were screened from Irish soils and are characterized under low cost carbon substrates for economic lipid production. Total of 247 fungi cultures were isolated from soil samples collected from various parts Ireland. Oleaginous 50 isolates were screened on glucose and starch at 3% concentrations respectively. The maximum lipid content in biomass was observed in the isolate I16-3, up to 44.3%. The lipid yield with respect to glucose consumed, YL/C (g lipids/g glucose consumed), YL/C values were in the range of 4.7 -14.0 g lipids/100 g of glucose consumed. The lipid content in biomass ranged from 19% to 39%; the maximum lipid content (39%) was observed in the same isolate I16-3. Interestingly, the isolate had a slightly higher lipid yield (4.3 g/L) when grown on 3% starch medium than 3% glucose medium (4.1 g/L). In addition to that 19 isolates were positive (+ve) for amylase secretion with a production of 34U/mL. Trichoderma sp., Penicillium sp., Aspergillus sp., Mortierella sp., Zygomycetes sp., Acremonium sp. and Umbiliopsis sp are the seven genera in which the oleaginous fungi were grouped.
