| 中文摘要 | microbial lipid production by rhodosporidium toruloides under sulfate-limited conditions |
| 英文摘要 | novel biochemical approaches remain to be developed to improve microbial lipid technology. this study demonstrated that sulfate limitation was effective to promote accumulating substantial amounts of intracellular lipid by the oleaginous yeast rhodosporidium toruloides y4. when it was cultivated using a medium with an initial carbon-to-sulfur (c/s) molar ratio of 46,750, cellular lipid content reached up to 58.3%. the time courses of cell growth, lipid accumulation and nutrient depletion were analyzed and discussed in terms of lipid biosynthesis. moreover, lipid accumulation under sulfate-limited conditions was effective regardless of the presence of a high concentration of nitrogen sources. thus, lipid contents almost held constant at near 57% in the media with an initial c/s molar ratio of 11,380 although the carbon-to-nitrogen molar ratio ranged from 28.3 to 5.7. taken together, our results established the sulfate-limitation approach to control lipid biosynthesis, which should be valuable to explore nitrogen-rich raw materials as the feedstock for lipid production.
