^a Theoretical lipid yields on glucose and xylose are described by Papanikolaou and Aggelis [38].
^b 39.6 g glucose and 21.6 g xylose can be obtained from 100 g wheat straw with dilute sulfuric acid pretreatment followed by enzymatic hydrolysis [36].
^c The biodiesel yield from direct methanolysis of M. isabellina biomass is 91.0% [37].
^d The current and potential annual wheat straw yields in US are 11 million dry tons and 57 million dry tons respectively [18].
