Review of Methods Used for Microalgal Lipid-Content Analysis

Abstract This paper provides a brief overview of most recent strategies that used to analyze microalgal lipid content, including NIR spectroscopy and TD-NMR methods etc. Common methods like gravimetric quantification and staining quantification are also introduced in this report. The physiology background of microalgal lipid accumulation is stated in order to clarify the purpose of each individual analytical method. After all, online lipid content measurement method that has good accuracy has the best chance to be generalized for all the lipid analyzing researches.
