hydrolysed corncob has been used to produce oil by fermentation
with the yeast strain Trichosporon dermatis, providing a lipid
content of 40% w/w [51]. Li et al. [52] hydrolysed rice straw by a
two-step process, including diluted acid pretreatment followed
by enzymatic hydrolysis, in order to achieve improved utilization
of hemicellulose and cellulose. The hydrolysate without
detoxification was employed as substrate in cultivations of
Trichosporon fermentans leading to a lipid concentration of
