“…Similar SEM images were also reported showing formation of pits during pulptreatment by T. versicolor (Garmaroody et al, 2012) and T. hirsuta yj9 (Sun et al, 2011). No traversal cracks and damage on the fiber surface was observed unlike fungal and physicochemical treated pulp that might decrease the mechanical strength of the fiber (Behera et al, 1996;Kim et al, 2003;Nlewem and Thrash, 2010).…”

“…The structural changes of pretreated corn stover could be contributed to the significant decrease of hemicellulose and lignin contents during this period. Some physical and chemical pretreatments gave the same results (Behera et al, 1996;Kim et al, 2003;Nlewem and Thrash Jr, 2010). The structure of pretreated samples showed great changes: the surface of corn stover became rugged; the fibers were separated with many small pores.…”

“…The hemicelluloses provide the link between lignin and cellulose. This lignin coating, when intact in the plant, reduces the accessibility of the cellulose for digestion by chemical and/or biochemical means for the production of fermentable sugars and liquid fuels [4]. Pretreatment(s) of the lignocellulosic materials before subjecting them to fermentable sugar production via enzymatic hydrolysis can resolve this problem.…”

In this study, the structural architecture of oil palm frond (OPF) after various pretreatment is evaluated through microscopic studies. Maximal degrees of saccharification of OPF are depended on pretreatment method used. Each pretreatment has its own effect(s) on the fiber of OPF. OPF is a solid waste generated by the palm oil industry that creates a problem for the industry in terms of waste management. This lignocellulosic waste material has many physio-chemical structural and compositional factors that hinder the enzymatic digestion of the cellulose present in the lignocellulosic biomass. A pretreatment is needed to alter or remove these structural and compositional impediments to hydrolysis in order to improve the rate of enzyme hydrolysis and increase the yield of fermentable sugars. The structural architecture of lignocellulosic fibres after various pretreatment e.g. chemical, biological and biochemical, were evaluated through light microscopic (LM), scanning electron microscopic (SEM) and transmission electron microscopic (TEM) studies. These pretreatments, both separately and intergrated, rendered the OPF biomass more susceptible and accessible to saccharification and increased the production of fermentable sugars. Morphological changes that took place in the lignocellulosic biomass included the removal of inhibitory materials, e.g. triterpenoids, silica, hydrocarbons, etc., production of cracks in the lignocellulosic fibres, and exposure of cellulosis materials by creating pores during pretreatment. The most effective pretreatment was autoclaving followed by enzymatic hydrolysis of the OPF. This combination of treatments resulted in a significant increase in reducing sugar production by creating pores due to the removal of silica and lignin from biomass, as observed in SEM studies.
