Ultrasound assisted oleaginous yeast lipid extraction and garbage lipase catalyzed transesterification for enhanced biodiesel production

While using microbial lipids as a biodiesel feedstock, effective extraction of lipids is essential. Also, the crude lipase produced from waste organics could be a potentially low-cost biocatalyst for the transesterification process. In this study ultrasound with the suitable solvent system was used for extracting the lipids from novel oleaginous yeast Naganishia liquefaciens NITTS2. Highest lipid recovery obtained was 99.3 ± 0.1% at optimized...
