  1. Cells were grown in 6% molasses with the addition of 3% SBP hydrolysate or (NH4)2SO4 in batch and pulsed fed-batch cultures. CDW, lipid production, lipid content and lipid yield were calculated after 144 h of growth. Lipid yield (gl/gs) was calculated considering the amount of glucose, sucrose and acetic acid consumed by cells
  2. ND not determined
