The structural architecture of lignocellulose fibres after various pre
treatments, i.e. chemical, physical and biochemical, was evaluated thr
ough SEM studies. These pretreatments, individual and integrated, rend
ered the biomass of C. procera more susceptible and accessible to sacc
harification and led to an increase in the production of fermentable s
ugars. The morphological changes that took place in lignocellulosic bi
omass included the removal of inhibitory materials like triterpenoids,
hydrocarbons etc., production of cracks on the lignocellulosic fibres
and exposure of cellulosic materials by the creation of pores during
pretreatments. The most effective pretreatment was found to be enzymat
ic delignification, which resulted in a remarkable increase in sugar p
roduction, about 21-fold, by creating pores due to the removal of lign
in from biomass, as revealed by SEM studies. Copyright (C) 1997 Elsevi
