It has been reported that such yeast oils can be used as oil feedstocks
for biodiesel production with the catalysis either by lipase or chemical catalyst (Li et al., 2008).
Compared to other plant oils, microbial oils have many advantages, such as short life cycle, less labor
required, less affection by venue, season and climate, and easier to scale up. In addition, oleaginous yeasts
can not only accumulate lipids within a short period of time but grow well on a variety of substrates, even
inexpensive material, such as nutritional residues from agriculture and industry, thus lowering the cost of
oils (Zhu et al., 2008). With the rapid expansion of biodiesel, microbial oils might become one of
potential oil feedstocks for biodiesel production in the future, though there are many works associated
with microorganisms producing oils need to be carried out further.
