Cassava tuber contains 70% starch of its dry weight and has
been used as the promising feedstock for fuel ethanol industry
(Zhang et al., 2003; Yu and Tao, 2009; Huang et al., 2010). As the
outcome, massive amount of cassave residues were also produced
as the by-products of ethanol production, nearly half ton of cassava
residues for producing one ton of ethanol (Zhang et al., 2011a). Be-cause of the high lignocellulose content in the cassava residues, its
nutritional value was low to be used as the distillers dried grains
with solubles (DDGS) as in the corn ethanol fermentation. Thus
the cassava residues were usually discarded as a solid waste in
the cassava ethanol industry. A reasonable utilization of the cas-sava residues for upgrading the cassava fuel ethanol value becomes
an important topic
