2) The content of microbial oils in fermented products is not only be decided by the genetic
characteristics of the cells, but also with the culture conditions. If we will explore the best pretreatment
method of the corn stalks further to improve the conversion rate of polysaccharide or if we will do
genetic transformation to Trichosporon cutaneum to improve the production rate of microbial oils and
also if we will explore the optimal fermentation conditions such as temperature, time, pH, dissolved
oxygen, agitation speed, inoculum size, medium etc. in the fermenter to gain the best fermentation
kinetics, the oil production is expected to increase further.
