| Abstract: |
| The oil producing strains were screened from the 178 strains marine fungi isolated from intertidal zone of Naozhou island in South China Sea using Nile red plates, then the fatty acid of the strains were extracted and methylated, and the total fatty acid content and fatty acid composition were analyzed by gas chromatography-mass spectrometry(GC-MS).The results showed that 89 strains of oil producing fungi were screened. Among them, the total fatty acid content of 14 strains of oil producing fungi was 1.41%-7.73% of the mass of freeze-dried strains. The contents of unsaturated fatty acid and polyunsaturated fatty acid were 42.51%-68.86% and 9.03%-36.49% respectively. The intertidal zone of Naozhou island in South China Sea was a rich resource for oil producing fungi, which had higher value in development and utilization of biolipid, and the unsaturated fatty acid obtained had wide application prospect. |
