Title
Single cell oil production from hydrolysates of inulin and extract of tubers of Jerusalem artichoke by Rhodotorula mucilaginosa TJY15a
Abstract

In this study, we found that Rhodotorula mucilaginosa TJY15a could accumulate 48.8% (w/w) oil from hydrolysate of inulin and its cell dry weight reached 14.8 g/l during the batch cultivation while it could accumulate 48.6% (w/w) oil and 52.2% (w/w) oil from hydrolysate of extract of Jerusalem artichoke tubers and its cell dry weight reached 14.4 g/l and 19.5 g/l during the batch and fed-batch cultivations, respectively. At the end of the fed-batch cultivation, only 0.04% of reducing sugar and 0.08% of total sugar were left in the fermented medium. Over 87.6% of the fatty acids from the yeast strain TJY15a cultivated in the hydrolysate of extract of Jerusalem artichoke tubers was C16:0, C18:1 and C18:2, especially C18:1 (54.7%). Therefore, the results show that hydrolysates of inulin and extract of Jerusalem artichoke tubers were also the good materials for single cell oil production.
