Among the 250 yeast strains screened for xylose assimilating capacity, eight oleaginous yeasts were selected by Sudan Black B test. The lipoid content of these 8 strains was resolved by soxhlet beginning method. unrivaled strain (T216) was found to produce lipids up to 36.6%, and it was identified as Rhodotorula glutinis. The surmount fermentation conditions were obtained as follows: glucose as carbon seed 100 g/L; yeast extract and peptone as nitrogen sources at, respectively, 8 and 3 g/L; initial pH of 5.0; vaccination volume of 5%; temperature at 28oC, shaking repair of clxxx r/min, cultivated for 96 h.

Under these conditions, R. glutinis amass lipids up to 49.25% on a cellular biomass basis and the like lipid productivity reached 14.66 g/L. Experiments with a 5-L bioreactor under the optimal destination conditions showed that R. glutinis accumulated lipids up to 60.69%, resulting in 23.41 g/L in lipid productivity. More encouraging results were observed for the lipid issue with alternative carbon sources. maize stalk and Populus euramevicana leaves hydrolysate could be employ to substitute glucose. Chemical abridgment indicated that biodiesel obtained by transesterification possess similar composition to that from vegetable oil, one of the widely...If you sine qua non to get a all-embracing essay, order it on our website: Ordercustompaper.com
