Dilute Acid Hydrolysis of Bagasse and Fermentation of the Hydrolysate to Produce Single Cell Protein
Both the cellulose and the hemicellulose components can theoretically be brokendownto produce a substratethat can be fermented by micro-organisms to produce SCPo Breakdown of the cellulose fraction produces a solution rich in glucose, whereas the hemicellulose portion provides predominantly a xylose solution. Xylose is a five carbon sugar which is generally fermented by a different group of mic...
متن کاملEvaluation of xylitol production using corncob hemicellulosic hydrolysate by combining tetrabutylammonium hydroxide extraction with dilute acid hydrolysis.
In this paper, we produced hemicellulosic hydrolysate from corncob by tetrabutylammonium hydroxide (TBAH) extraction and dilute acid hydrolysis combined, further evaluating the feasibility of the resultant corncob hemicellulosic hydrolysate used in xylitol production by Candida tropicalis. Optimized conditions for corncob hemicellulose extraction by TBAH was obtained via response surface method...
متن کاملHydrolysis of sweet sorghum bagasse and eucalyptus wood chips with liquid hot water.
The chemical composition, hydrolysis products, and kinetics during liquid hot water pretreatment of sweet sorghum bagasse (SSB) and eucalyptus wood chips (EWC) were investigated. Under optimal conditions, a total xylose recovery of 79.6% and 55.6% for SSB and of 74.9% and 84.4% for EWC was achieved after pretreatments in a step-change flow rate reactor (184 °C, 20 ml/min, 8 min, and 10 ml/min, ...
متن کاملImprovement of sweet sorghum bagasse hydrolysis by alkali and acidic pretreatments
The present work deals with enzymatic hydrolysis of sweet sorghum bagasse to fermentable sugars. The bagasse was treated with phosphoric acid and sodium hydroxide prior to enzymatic hydrolysis by commercial cellulase and β-glucosidase. The phosphoric acid pretreatment was performed at 50°C for 30 min, while 12% NaOH was used for the alkali treatment at 0°C for 3 h. The phosphoric acid pretreatm...
