Fermentation kinetics and ethanol production from different sweet sorghum varieties
In recent years bioethanol fuels derived from agricultural biomass resources or waste have been considered the cleanest liquid fuel alternative to fossil fuels. Ethanol consumption is expected to reach 11.2 billion gallons by 2012. Sweet sorghum, grown in the Southeast and Midwest states in US, contains 14%-20% fermentable sugar and is an ideal feedstock, owing to its ease of fermentation by ye...
متن کاملApplication of very high gravity technology to the cofermentation of sweet stem sorghum juice and sorghum grain
Ethanol production from mixtures of sweet stem sorghum juice and sorghum grain was investigated under normal and very high gravity (VHG) fermentation conditions. Fermentation was carried out using Saccharomyces cere6isiae yeast strain N96 at 30°C. For VHG fermentation, sucrose was added to the sweet sorghum juice to obtain a concentration of 34 g per 100 ml of dissolved solids. Fermentation was...
متن کاملEfficient extraction method to collect sugar from sweet sorghum
BACKGROUND Sweet sorghum is a domesticated grass containing a sugar-rich juice that can be readily utilized for ethanol production. Most of the sugar is stored inside the cells of the stalk tissue and can be difficult to release, a necessary step before conventional fermentation. While this crop holds much promise as an arid land sugar source for biofuel production, a number of challenges must ...
متن کاملEthanol production from sweet sorghum juice under very high gravity conditions: Batch, repeated-batch and scale up fermentation
Batch ethanol fermentations from sweet sorghum juice by Saccharomyces cerevisiae NP 01 were carried out in a 500 ml air-locked Erlenmeyer flask under very high gravity (VHG) and static conditions. The maximum ethanol production efficiency was obtained when 9 g l of yeast extract was supplemented to the juice. The ethanol concentration (P), productivity (Qp) and yield (Yp/s) were 120.24 ± 1.35 g...
متن کاملDried Spent Yeast and Its Hydrolysate as Nitrogen Supplements for Single Batch and Repeated-Batch Ethanol Fermentation from Sweet Sorghum Juice
Dried spent yeast (DSY) and its hydrolysate (DSYH) were used as low-cost nitrogen supplements to improve ethanol production from sweet sorghum juice by Saccharomyces cerevisiae NP01 under very high gravity (VHG) fermentation (280 g·L of total sugar) conditions. The supplemented DSY and DSYH concentrations were 11, 16 and 21 g·L, corresponding to a yeast extract nitrogen content of 6, 9 and 12 g...
متن کاملSweet sorghum R&D at the Nimbkar Agricultural Research Institute (NARI)
The research work on sweet sorghum carried out at the Nimbkar Agricultural Research Institute (NARI) during last twenty-five years has been summarized. American lines were crossed with a local Indian fodder/grain variety to produce varieties with a juicy stalk and good quality grain. Further breeding was carried out to produce varieties and hybrids giving high yield of good quality grain while ...
