Cellulosic substrates were also used by Arthe et al., (32) for bioethanol production by microbial
extracellular enzymatic hydrolysis and fermentation where a yield of 8.9g/l was recorded.
In another report
of Vaithanomsat et al., (33) bioethanol was produced from enzymatically saccharified sunflower stalks
where the yield of 0.02g/100g was obtained. Enzymatically pretreated agricultural residues were also used
by Seema Patel et al., (34) for ethanol production by different fungal cultures. The results obtained in our
study are in correspondence with these reports.
