Description
Summary:Cellulose nanocrystal (CNC) is a biopolymer which has wide application in packaging industries, biomedical fields etc due to its some desirable characteristics like biodegrade ability, thermal stability etc. This is produced from different lignocellulosic biomass by different chemical and physicochemical methods which released more hazardous discharge and not eco-friendly. The enzymatic method can be the alternative and sustainable method for CNC production. Palm oil empty fruit bunch (OPEFB) fibers is a major biowaste material from edible oil industries in Malaysia has no measurable value-added products processing. So, there is looking for environmentally friendly and green process to convert OPEFB to biopolymer like CNC. In this research work, CNC was produced from the extracted cellulose fibers from OPEFB which was delignified by commercial free laccase and hydrolyzed using free cellulase as a biocatalyst. Field emission scanning electron microscopy (FESEM) was used to examine the morphology of the products. The yield of that was reached to 22.53% (w/w) from the enzyme pre-treated 2% (w/v) OPEFB cellulosic fibers from 96 h hydrolysis by 80 International unit of cellulase enzyme. Nano-dimension of CNC was revealed under FESEM in the morphological study. So, the production of CNC from OPEFB may be value added to the product which support waste to wealth concept. The isolated CNC from pretreated OPEFB cellulosic fibers shows a promising characteristic, and the enzymatic hydrolysis is a potential method for CNC production which is environmental friendly.
