“…Crystallinity index (CrI) was calculated according to the method described in section II part E, with results presented in Fig 3. Crystallinity index increased by 6.3% as a result of laccase treatment. A similar observation was made by [23] and [22] who studied the effect of laccase on cellulosic fibre and crystallinity index increased up to 22% and 10% respectively. Crystallinity index of flours is shown in Fig3; it can be observed that CI for laccase treated flour recorded the highest value (increase).…”

“…The intensity of the peak at 1184 cm -1 of 5%NaOH+Laccase was weaker suggesting that hemicellulose loss was greater than all other spectrums. Amorphous and crystallinity content of cellulose are assigned cellulose absorption bands 1335-1316 cm -1 [22]. Overall, there are strong links that exist between FTIR spectra, the XRD and microstructure (SEM) of laccase modified mukwa.…”

“…Crystallinity index is one of the principal factors to consider when determining the mechanical and physical behavior of cellulose fibres [22]. Figs 2 and 3 show the X-ray diffractograms and crystallinity index (CI) results of untreated and treated mukwa flours.…”

“…Laccase is a well-studied oxido-reductase enzyme, it takes part in polymerization as well as depolymerization of lignin compound through free radical reaction (Nasir et al, 2013). Since, laccase enzymes are too large to penetrate into fibers (55-80 kDa), it modifies the amorphous extracellular component only (Gochev and Krastanov, 2007).…”

“…Thus, this study deals the pretreatment reaction of laccase at two different times, on natural fiber and the result was compared with untreated fiber. Such improved fibers can be used in many industrial applications like fiber board, pulp and paper industries etc (Virk et al, 2012;Nasir et al, 2013;Wu et al, 2011). This work aims to improve the physico-chemical properties of rubber wood fiber by laccase hydrolysis in order to improve the crystalline structure.…”

Cellulose and lignin are the two most abundant polymers found in plant cells. Cellulose microfibrils provide mechanical properties to woody cell whereas, hemicelluloses and lignin act as glue in between the crystalline cellulose. Cellulose crystallinity directly affects the physico-chemical behavior of the individual fiber such as modulus, hardness, stiffness, tensile and swelling-shrinkage properties and ultimately to its product. This study aims to improve the physico-chemical properties of rubber wood fiber by laccase hydrolysis in order to improve the crystalline structure. Two different times of reactions i.e., 60 and 120 min were applied at constant temperature 25°C, enzyme concentration 7 U gG 1 and pH 5. After the pulp treatment, fibers were sieved out and transferred in to autoclave at 121°C for 15 min to stop further enzyme reaction. Treated fiber was dried in electric oven drier at 80-90°C for 24 h to dry up the fiber until zero moisture content. Crystallinity index of the fiber was measured by X-ray diffraction method and it was observed maximum up to 14% higher compared to untreated fiber. The treated fiber was further analyzed for elemental composition, FE-SEM and TGA and compared with untreated fiber in order to evaluate its properties. Fiber treated with enzyme exhibited superiority in fiber surface structure and thermal degradation over untreated fibers. A fiber with improved mechanical strength and crystalline structure can be utilized for various purposes to produce high quality product.
