An improved method for processing corn into ethanol and other valuable co-products. The invention generally involves a multi-step process which produces germ (or oil), protein, and feed yeast as its co-products while maintaining or enhancing the provision of fermentable sugar to ethanol fermentation. This is accomplished by fundamentally altering the way the corn is fractionated, disrupting the cell walls rather than the protein matrix as is done in conventional wet milling.

The invention provides a method for the direct biological production of calcium magnesium acetate using a novel combination of an aerobic thermophilic bacterium of the genus Bacillus, capable of supporting the sustained production of substantial quantities of acetic acid at low pH, high temperatures, and high salt concentrations. Strains of bacterium of the genus Bacillus selected and isolated for use in the present invention produce acetic acid in the presence of a neutralizing source of calcium and magnesium ions, such as dolomitic lime, to produce substantial quantities of calcium magnesium acetate.

Stabilized cleaning compositions comprise a biochemical soil degrading enzyme, a slow release oxidant bleach composition and an effective amount of a reducing agent to prevent the appearance of an enzyme deactivating concentration of oxidant bleach composition permitting the enzyme to degrade biochemical soils before bleaching action begins.
