| Abstract: | Objective] To optimize the Soxhlet extraction parameters of microalgal lipids for further research.Method] Microalgal lipids were extracted from Synechococcus sp.with Soxhlet extraction method.And the effects of different liquid to solid ratios,extraction time and extraction temperatures on the extraction efficiency were studied to obtain optimal parameters.Result] The extraction efficiency was the highest when liquid to solid ratio was 6 ml/109 cell,extraction time was 4 h and extraction temperature was 95 ℃.And the content of microalgal lipids was 0.125 mg/108 cell.Conclusion] This study provided a basis for further optimizing the extraction process of microalgal lipids. |
