- Abstract
In this study, the yeast strain P5 isolated from a mangrove system was identified to be a strain of Aureobasidium pullulans var. melanogenum and was found to be able to secrete a large amount of heavy oil into medium. After optimization of the medium for heavy oil production and cell growth by the yeast strain P5, it was found that 120.0 g/l of glucose and 0.1 % corn steep liquor were the most suitable for heavy oil production. During 10-l fermentation, the yeast strain P5 produced 32.5 g/l of heavy oil and cell mass was 23.0 g/l within 168 h. The secreted heavy oils contained 66.15 % of the long-chain n-alkanes and 26.4 % of the fatty acids, whereas the compositions of the fatty acids in the yeast cells were only C (21.2 %), C(2.8 %), C (2.9 %), C (39.8 %), and C (33.3 %). We think that the secreted heavy oils may be used as a new source of petroleum in marine environments. This is the first report of yeast cells which can secrete the long-chain n-alkanes.
