Recent studies have proven ethanol to be an ideal liquid fuel for transportation and renewable lignocellulosic biomass to be an attractive feedstock for ethanol fuel production by fermentation (1,2). The major fermentable sugars from hydrolysis of lignocellulosic biomass, such as rice and wheat straw, sugarcane bagasse, corn stover, corn fiber, softwood, hardwood, and grasses, are D-glucose and D-xylose except that softwood... 

Concentrate the sample (remove acetone) under nitrogen to ca 20-25 mL using a TurboVap (water-bath at 50 °C). Transfer the sample into a 50-mL polypropylene centrifuge tube. Rinse the TurboVap vessel with 5 or lOmL of pFI 6 buffer solution. The amount of pH 6 buffer required depends on the matrix being analyzed and should be determined as needed. All matrices need 5 mL of the buffer solution to adjust the sample to pH 6, except for sweet corn (ears, forage, and stover), which requires 10 mL. Add the rinse buffer to the sample. Rinse the TurboVap vessel with 10 mL of hexane and add the hexane to the sample.

As mentioned above, wet corn-mills of >1 Mt a-1 capacity are already in operation [79]. Such a scale is economical for corn because it has a high density and is easily transportable. However, it is not necessarily economical for straw, corn stover and numerous crop residues, which are characterized by a low density and fibrous structures.

Several researchers have shown that alkali present in the feedstock influences the yields and compositions of the pyrolysis products [56, 59]. An interesting result was reported by Brown and coworkers [60] who found that addition of (NH4)2S04 as catalyst to the pyrolysis of dematerialized (alkali free) corn stover resulted in a pyrolysis oil that contained 23 wt.% levoglucosan (normally 1-3 wt.% levoglucosan is present in pyrolysis oil). Levoglucosan is a component from which various fuel blends and chemicals can be produced.

Maximum Removable Corn Stover Quantities (Million Metric Tons at Harvest) by Rotation and Tillage Practice When All Cropland Acres in Each State Are Planted to the Rotation"... 

The estimated quantities of removable corn stover and wheat straw presented in Tables 7 and 8 conform to intuitive expectations in that as tillage operations become less intensive (i.e., go from conventional to no-till), the amounts of removable residue increase across all rotations in all states. Differences in estimated removable quantities among states is a function of several factors including production location (whether the majority of production occurs in areas that have highly erodible soils and field topology nonconducive to removal), climatic/erosive conditions at the locations of production, and actual yields at these specific locations among others. These factors must be considered before residues can be removed at any specific location.

Hydrodynamic Separation of Grain and Stover Components in Corn Silage... 

After ensiling, grain has been sorted from stover, at least partially, by mechanical sieving (3) or aerodynamic separation (4). Hydrodynamic separation has not previously been used for corn silage, but it is used industrially to separate heavier particles such as phosphatides from corn oil in the wet-milling process (5).
