“…The production of PKC in Malaysia has increased in recent years so that 2,520,000 tons of PKC were produced during 2015 (MBOP 2016). The study on the PKC structure has shown that it contains a high amount of polysaccharide (50%), with a high hemicellulose content (Cerveró et al 2010). Similar studies have shown that cellulose constitutes about 11.6% of PKC polysaccharide, and the hemicellulose composition of PKC includes a large amount of mannan (57.8%) with a lower quantity of xylan (3.7%) (Ong et al 2004).…”

“…Most of the PKC content was mannan, with some cellulose and a small amount of arabinoxylan and 4-O-methyl-glucoronoxylan (Cerveró et al 2010;Jørgensen et al 2010). Preliminary enzymatic hydrolysis of PKC was evaluated using mannanase enzyme with various enzyme loadings, namely 5% and 10% (w/wsubstrate), to determine the effect of enzyme loading on the amount of sugars released from pretreated-PKC.…”

The viability of most fermentation processes is very much dependent on the cheap fermentation medium used. Palm kernel cake (PKC) is an abundant biomass generated from the palm oil processing industry that can be used as the carbon source for the growth and production of acetone-butanolethanol fermentation (ABE) by Clostridia. In this study, ABE production from the fermentation of PKC using Clostridium acetobutylicum YM1 in a batch culture was conducted. The PKC was subjected to treatment with acids (sulphuric and hydrochloric acids), alkali (sodium hydroxide and alkaline peroxide), enzymatic hydrolysis, and hydrothermal treatment (in autoclave). The sulphuric acid-treated PKC (2% SAPKC) method produced the highest concentration of reducing sugars (30 g/L) compared with the other methods applied. The results showed that increasing the concentration of H2SO4 up to 3% decreased the amounts of generated reducing sugars to 20.4 g/L, which is about 32% less. The fermentation of 1%, 2%, and 3% SAPKC resulted in the production of ABE of 1.07, 5.72, and 3.48 g/L, respectively. This study showed that the pretreatment of PKC improved the content of fermentable sugars and subsequently enhanced the production of ABE by C. acetobutylicum YM1. This study also revealed that PKC can be regarded as a potentially low cost substrate for ABE fermentation.

“…When compared to fossil fuels, bioethanol burns completely and cleanly, producing only water and carbon dioxide, while at the same time enhancing petrol performances (Altintas et al 2002;Yamashita et al 2010). Most bioethanol is produced by the fermentation of carbohydrate from sugar cane, cane juice, corn starch, grains and potato starch using fermenting organisms such as Saccharomyces cerevisiae and Zymomonas mobilis (Cervero et al 2010;Vincent et al 2011a). This is known as first generation bioethanol and its production uses crop-based raw materials.…”

“…Thus, second generation bioethanol was introduced by utilizing lignocellulosic biomass to save cost and to meet the increasing world-wide demand for bioethanol (Vincent et al 2014). Lignocellulosic biomass is an abundant source of carbohydrate such as cellulose, hemicellulose and can be found in agricultural waste, forest waste and food-based industrial waste as such palm oil empty fruit bunch (EFB) and sago hampas (Adeni et al 2010;Cervero et al 2010;Zakaria et al 2014Zakaria et al , 2013. Sago hampas is a by-product from sago (Metroxylon sagu) processing factory after starch extraction.…”

Objective: Many methods for enzymes immobilization and large number of carriers for immobilized enzymes, there are many benefits and diffeculties for immobilization, so the objective of this paper is to determine the suitable method and carrier for cellulase immobilization.Methods: Three methods used for immobilization which they adsorption, Glutaraldehyde and modified glutaraldehyde using two different carriers the first anion exchanger AM-21-A, and the second cation exchange fiber VION KN -1. Results:The result shows that the degree of saving catalytic activity for immobilized and free cellulase were 35, 55, and 75% for the three methods respectively and The result of degree maintain of specific activity for native enzyme were 57%, 42%, for the two carriers VION KN-1, AM-21-A respectively. Conclusions:It can be concluded that the modified glutaraldehyde is the best method for cellulase immobilization and VION KN-1 is better carrier than AM-21-A.
