“…Ishola et al (2014) developed a different pre-treatments of EFB to produce bioethanol. The study resulted ethanol of 4.1 g/L by without pre-treatment of EFB after 96 h of fermentation; 62.8% after 48 h of simultaneous saccharification and fermentation (SSF) with combination of biological and chemical pre-treatment; and 89.4% after SSF with only pre-treated by phosphoric acid.…”

“…Lignocellulosic biomass from industrial and agricultural residues is considered to be an ideal substrate for the production of bioethanol because it is the most abundant renewable feedstock on the planet and does not compete with foods for human beings, and the use of the biomass supports an environmentally sustainable process [2][3][4][5]. However, although lignocellulosic materials contain 70% carbohydrates (cellulose and hemicellulose), several pretreatments are necessary in order to convert carbohydrates to fermentable sugars [6][7][8][9].…”

We previously isolated 18 Saccharomyces cerevisiae strains from coconut toddy in Sri Lanka. All the 18 strains (SLY-1 to SLY-18) could grow aerobically up to 18 mmol L À1 vanillin in yeast extract-peptone-dextrose (YPD) medium, and the SLY-10 strain showed the highest vanillin tolerance (up to 21 mmol L À1 ). Among these 18 strains, even in the presence of 24 mmol L À1 vanillin, five strains (SLY-3, SLY-4, SLY-8, SLY-9 and SLY-10) produced alcohol at 72 h in the range of 11.4-33.1 g L À1 and the SLY-10 strain showed highest alcohol production. The five strains showed the conversion of vanillin to vanillyl alcohol. They also tolerated other strong inhibitors: 4-hydroxybenzoic acid (24 mmol L À1 ), furfural (30 mmol L À1 ), 5-hydroxymethyl-2-furaldehyde (5-HMF, 36 mmol L À1 ) and acetic acid (75 mmol L À1 ). All these five strains showed no growth and no alcohol production when cultured in the medium with inhibitor mixture of 2.7 mmol L À1 vanillin, 30 mmol L À1 furfural, 30 mmol L À1 5-HMF, 75 mmol L À1 acetic acid and 75 mmol L À1 formic acid but showed significant growth and alcohol production of 16.2-32.7 g L À1 with inhibitor mixture of 30% concentration (0.81 mmol L À1 vanillin, 9 mmol L À1 furfural, 9 mmol L À1 5-HMF, 22.5 mmol L À1 acetic acid and 22.5 mmol L À1 formic acid). The four strains (SLY-3, SLY-4, SLY-8 and SLY-9) were shown to tolerate the inhibitor mixture to a similar extent and better than SLY-10, while SLY-10 was the best to vanillin alone. ARTICLE HISTORY

“…This is done to open up the lignocellulosic structure and to improve cellulose digestibility (Zhao et al 2012;Ishola et al 2014). For cellulase production, pretreatment processes are required to alter the substrate's physicochemical characteristics to aid microbial utilisation and enzyme induction (Brijwani and Vadlani 2011).…”

A mixed substrate (MS) comprising oil palm empty fruit bunch (EFB), oil palm frond (OPF), and rice husk (RH) was evaluated for endoglucanase production by Bacillus aerius S5.2. Effects of sulphuric acid, sodium hydroxide, N-methylmorpholine-N-oxide (NMMO), and hydrothermal pretreatments on endoglucanase production were investigated. Endoglucanase production by B. aerius on the untreated (0.677 U/mL) and pretreated MS (0.305 -0.630 U/mL) was generally similar, except that the acid (0.305 U/mL) and hydrothermal (0.549 U/mL) pretreatments that were more severe consequently produced significantly lower titres. Alkali pretreatment supported the highest enzyme production (0.630 U/mL) among all pretreatments that were studied. When endoglucanase production on the alkali-pretreated MS and single substrates (SS) was compared, alkali-pretreated EFB produced a titre (0.655 U/mL) similar to the MS, and this was significantly higher than titres recorded on OPF (0.504 U/mL) and RH (0.525 U/mL). Lower enzyme production was found to be consistent with higher pretreatment severity and greater removal of amorphous regions in all the pretreatments. Furthermore, combining the SS showed no adverse effects on endoglucanase production.
