A method for fermenting carbohydrate-rich crops is provided. Sugar beet, sugar cane, sweet sorghum, tropical maize hybrids and fruits are rich in simple sugars; potato, sweet potato, cassava and yam are rich in starch; and Jerusalem artichoke is rich in inulin. This method uses vacuum infusion to infuse yeast into the intercellular space (apoplast) of the parenchyma tissue. The simple sugars diffuse into the apoplast, come into contact with the yeast and produce ethanol. Ethanol can be extracted from the crop by vacuum stripping or crushing or can be left inside the starchy crop to preserve it. In some variants, pectinase enzymes degrade the parenchyma cell walls to speed up diffusion of simple sugars to the yeast, speed up diffusion of amylase to starch granules or speed up diffusion of inulinase to insoluble inulin.

Methods for fermenting carbohydrate-rich crops

A method for operating an internal combustion engine utilizing a fuel mixture containing a suspension in air at a concentration of about 200 mg of fuel per liter of air, of a solid fuel including at least one of a cereal flour, a cotton flour, a soybean flour, a potato flour, a cassava flour, a dehydrated chocolate powder and a dehydrated milk powder, the solid fuel being in the form of a powder having an average particle diameter and median particle diameter at least 150 .mu.m.

Starch is recovered from an amylaceous material such as manioc root or corn in the form of an aqueous slurry containing substantially all of the soluble components, e.g., carbohydrates and proteins, of the amylaceous material prior to processing. To accomplish such recovery, amylaceous material is milled in one or more steps in the presence of water to provide a slurry containing liberated starch particles and non-starch components. The initial aqueous starch slurry is then concentrated by removal of water therefrom. The water removed from the initial starch slurry contains soluble elements of the starch and is recycled to restore these elements to the starch recovery system.
