Alcohol production from pineapple waste

Abstract

Saccharomyces cerevisiae andZymomonas mobilis were grown on pineapple waste and their alcohol production characteristics compared. The pineapple waste consisted of 19% cellulose, 22% hemi-cellulose, 5% lignin and 53% cell soluble matters but concentration of soluble sugars, which included 5.2% sucrose, 3.1% glucose and 3.4% fructose, was relatively low and pretreatment of the substrate was needed. Pretreatment of pineapple waste with cellulase and hemi-cellulase and then fermantation withS. cerevisiae orZ. mobilis produced about 8% ethanol from pineapple waste in 48 h.

Potential utilization of sorghum field waste for fuel ethanol production employing Pachysolen tannophilus and Saccharomyces cerevisiae

“…This natural and potentially cheap and abundant polymer (lignocellulose) is composed of three main fractions: cellulose ($45% of dry weight), hemicellulose ($30% of dry weight) and lignin ($25% of dry weight) and found as agricultural waste (wheat straw, corn stalks, rice straw, sugar cane bagasses), industrial waste (pulp and paper industry), forestry residues, municipal solid waste etc., (Wiselogel et al, 1996). Various industrial and lignocellulosic wastes including cassava (Amutha and Gunasekaran, 2000), jack fruit seeds (Mariappan and Murugesan, 2005), aquatic weeds, corn field wastes (Sathesh-Prabu and Murugesan, 2010), pine apple wastes (Ban-Koffi and Han, 1990) can be used as a substrate for the production of ethanol.…”

Utilization of Pineapple Waste: A Review

“…Organisms like Saccharomyces cerevisiae and Zymomonas mobilis were used for ethanol fermentation (Ban-Koffi and Han, 1990). However, they have claimed that fermentable sugars which included sucrose, glucose and fructose were relatively low and pretreatment of the substrate with enzymes , the ethanol production was 92.5% of the theoretical value.…”

Bioethanol Production From Pineapple Wastes

“…Though the EY obtained appears rather low, due of course to the low sugar content, this could be attractive because TY, calculated on dry matter loss, was in a range around 90-96%, making these wastes an excellent raw material for ethanol production by S. cerevisiae NCYC 2826, as compared with previous studies on juice or rotten pineapple (Ban-Koffi & Han 1990;Nigam, 1999a;Nigam, 2000;Hossain & Fazliny, 2010).…”

“…The dry matter content in pineapple waste is around 10%, and composed of about 96% organic and 4% inorganic matter (Abdullah, 2007). These materials exhibit both high biochemical oxygen demand (BOD) and chemical oxygen demand (COD) values (Ban-Koffi & Han, 1990), and give rise to serious pollution problems if not properly disposed of.…”
