Table 4 Predictive estimation of the physical characteristics of biodiesel potentially obtainable from lipids produced by Leucosporidium creatinivorum DBVPG 4794, Naganishia adeliensis DBVPG 5195 and Solicoccozyma terricola DBVPG 5870 grown on steam-exploded and hydrolyzed CS (cardoon stalks), SD1, SD2 (stranded driftwood), OTPR1 and OTPR2 (olive tree pruning residues) at 20 and 25 °C

From: Yeast lipids from cardoon stalks, stranded driftwood and olive tree pruning residues as possible extra sources of oils for producing biofuels and biochemicals
