The present invention relates to a plant flour material comprising a ground, dried plant material, wherein the plant material contains a recombinant protein comprises a bactericidal or an insecticidal protein toxin, or combinations thereof.

Provided are a method for producing highly nutritious, softened plant material that retains the form of the plant material, and softened plant material obtained using said production method.

Bioactive apolar extract of plant material containing plant genetic material to treat mammalian diseases and disorders.

The process includes homogenizing a plant material in the presence of an extraction solvent to reduce the plant material to a plant liquid component and a plant pulp component.

The harvested plant material degradation system can include polyculture plant material or photosynthetically produced material obtained from a single species of plant.

The method can include fractionating the plant material.

Preferably, the plant material (16) comprises tobacco.

The cutting blades are configured to interact with the plant material so as to sever the plant material into stem segments.

The space is filled with an insulating material (9) which comprises pellets of expanded, vegetable material.

According to the invention, the treated plant material has the colour and texture of fresh plant material and is substantially free from curling or distortion.

The plant material is preferably actively growing in the submerged culture.

The present invention provides a use for the cellulose portion of a plant material, which is the portion left over after processing the selected plant materials to separate the hemi-cellulose and lignin from the cellulose.

Plant material has bacteriophage has been attached, wherein the bacteriophage retains infectivity.

The first filter segment (11) comprises cut or shredded plant material.

The bar may be of wood, cardboard, fibrous plant material, or a biodegradable synthetic plastics material.
