The influence of lipid concentration on hydrolysis and biomethanation of a lipid-rich (triolein) model waste was … evaluated in batch. The effect of increasing the concentration of lipid from 5% to 47% (w/w), based on chemical oxygen demand …–10 days was observed for all tests. The methane production rate observed was similar for tests with 5%, 10% and 18% lipid (w …

After the lipid contents in 7 strains of Rhodosporidium toruloides were determined, R. toruloides 21167 among them was … found to be able to produce the highest amount of lipid in its cells. Many ions, such as Mn2+, Ca2+, Zn2+ and Fe3+ had … positive effects on lipid accumulation by R. toruloides 21167. After the yeast was cultivated in the medium containing 8 …
