Ethanol fermentation of cassava starch pretreated with alkali

Ethanol Fermentation of Starch from Field Peas

Cereal Chem. 82(5):554-558 Field peas (Pisum salivum) were evaluated as a potential feedstock for ethanol production. Ground peas were dry-milled and separated into starch, protein, and fibrous fractions by air classification. Starch-enriched fractions prepared from whole peas and dehulled peas contained 73.717c wt and 77.8% wt starch, respectively, a nearly two-fold enrichment compared with wh...

Improved Ethanol Production Based on High Solids Fed- Batch Simultaneous Saccharification and Fermentation with Alkali-Pretreated Sugarcane Bagasse

Alkali-pretreated sugarcane bagasse fiber was subjected to fed-batch simultaneous saccharification and fermentation (SSF) with a prehydrolysis process to increase the solids loading and produce a high concentration of ethanol. The hydrolysis medium and yeast feeding modes were investigated to determine suitable conditions for high sugar yield and ethanol production. Batch addition resulted in a...

Simultaneous Saccharification and Fermentation of Cassava Waste for Ethanol Production

Enzymatic Saccharification and Ethanol Fermentation of Reed Pretreated with Liquid Hot Water

Reed is a widespread-growing, inexpensive, and readily available lignocellulosic material source in northeast China. The objective of this study is to evaluate the liquid hot water (LHW) pretreatment efficiency of reed based on the enzymatic digestibility and ethanol fermentability of water-insoluble solids (WISs) from reed after the LHW pretreatment. Several variables in the LHW pretreatment a...

Simultaneous saccharification and ethanol fermentation of oxalic acid pretreated corncob assessed with response surface methodology.

Response surface methodology was used to evaluate optimal time, temperature and oxalic acid concentration for simultaneous saccharification and fermentation (SSF) of corncob particles by Pichia stipitis CBS 6054. Fifteen different conditions for pretreatment were examined in a 2(3) full factorial design with six axial points. Temperatures ranged from 132 to 180 degrees C, time from 10 to 90 min...
