In this study Trichoderma harzianum and Aspergillus sojae,
which were able to ferment cellulose or several sugars to bioethanol
were chosen besides the yeast, S.cerevisiae, because of
aforementioned advantages. This way, in addition to initial
reducing sugars, remaining cellulosic compounds in hydrolysates
could be fermented into bioethanol as well. A pre-growth cyclewas
applied in order to increase bioethanol production by enhancing
the mass of mycelia used in the fermentation
