There has been increasing interest in seeking alternative lipid sources for biodiesel
production. Although it is economically viable to use corn syrup for DHA production [4]and it was almost economically viable to use cheese whey for cocoa butter equivalent production [2], recent research on using glucose as feedstock for heterotrophic microalgae culture to produce biodiesel showed disappointing results due to high costs [5]. Biomass hydrolysates were tested and believed to be good feedstock for single cell lipid production, but this approach faces the same economical problem with cellulosic bioethanol
production, which is how to produce sugar from cellulosic biomass at a sufficiently low cost. However, using organic waste should provide an option to greatly decrease production costs, since it has negative value. For example, monosodium glutamate wastewater has been determined to be a good feedstock [7, 8]. However, this single source is limited in
quantity and thus similar waste streams need to be investigated.
