Özet

This study was performed to produce linoleic acid-rich lipids in molasses-based medium using locally isolated fungus Galactomyces geotrichum TS61 (GenBank accession: MN749818). The most favorable culture conditions for lipid production were determined as 200 ml/L molasses, 1.5 g/L ammonium sulfate, 1.5 g/L KH2PO4, pH 6, and 8 days incubation time. Maximum values of cell concentration, lipid concentration, and lipid content were 17.1 g/L, 11.9 g/L, and 69.6%, respectively. Polyunsaturated fatty acids (PUFAs) (42.49%) accounted for the majority of fatty acids in this fungus. Linoleic acid (23.67%) was the most abundant fatty acid followed by oleic acid (22.14%). Minor fatty acids were palmitoleic acid, stearic acid, palmitic acid, pentadecanoic acid, and myristic acid. Fatty acid analyses show that lipids of this fungus may be used as food supplement and/or medicinal therapeutics. The lipid production by G. geotrichum in molasses-based medium was investigated for the first time in this study.
