This study was aimed to explore the effects of different methyl esterification methods on the production of fatty acids from Schizochytrium.In this paper,the pure algae bodies were obtained by fermentation and culture,then the dried algae were acquired by enzymatic breaking and freeze-drying,soxhlet extraction method was used to extract the oil from the dried mycelium of Schizochytrium. The fatty acids in algal oil were esterified by three different methyl esterification methods,the composition and content ...
