Abstract: The present invention provides a method of retarding rootlet formation from one or more plants in a medium that can support the growth thereof, which method includes introducing into the medium a growth inhibiting effective amount of a growth inhibitor which comprises corn steep liquor. In other embodiments, the growth inhibitor is a mixture of a growth medium and lactic acid. In preferred embodiments, the present invention further provides a malting composition that includes a fermentable grain and a growth inhibitor, wherein the growth inhibitor is present in an amount effective to retard rootlet formation.

Abstract: The present invention provides a means to concentrate, dry and formulate biomaterials such as polysaccharides, gums and related biopolymers, and microorganisms such as cells, spores, and the like from dilute solutions using spent germ and other oil bearing residues. In addition, the spent germ can serve as a carrier for such biomaterials. The sorbed materials are useful in animal feeds.

Abstract: A single, simple, uniform protocol for the rapid large scale purification and crystallization of ribulose 1,5-bisphosphate carboxylase (RuBisCO) to a greater than 90% purity from a wide variety of plant species, involving the steps of grinding and homogenizing plant material, such as leaves, with a suitable, acqueous buffer solution. The solution is filtered and the residue discarded. While maintaining temperature and pH control, sufficient quantities of polyethylene glycol (PEG) are added while stirring to bring the final concentration of PEG in the range of 8 to 15 (weight/volume) percent. To enhance crystal formation, magnesium chloride can be added to the solution. The precipitated material is discarded and the pure RuBisCO crystals which separate out of the remaining supernatant are collected, washed, dried and stored.
