The present disclosure relates to compositions and processes in the field of self-cleaning system using digestive proteins. One composition includes a substrate, a digestive protein capable of decomposing a stain molecule, and a linker moiety bound to both said digestive protein and said substrate. The processes include binding a substrate to a surface and forming a linker moiety between a digestive protein and said substrate.

A process is provided for releasably encapsulating a biological entity. The process comprises combining a solution of a surfactant in a non-polar solvent with a precursor material and the biological entity to form an emulsion. The emulsion comprises a polar phase dispersed in a non-polar phase, wherein the polar phase comprises the biological entity. The particles comprising the biological entity are then formed from the polar phase.

The present invention relates to protease variants and methods for obtaining protease variants. The present invention also relates to polynucleotides encoding the variants; nucleic acid constructs, vectors, and host cells comprising the polynucleotides; and methods of using the variants.

The invention relates to proteases with enhanced water hardness tolerance and to protease-containing washing or cleaning agents.

A process for treating brewers spent grains for producing a high value protein product and a cellulosic residue, both from brewers spent grains that have not gone through fermentation. The high value protein product is useful as a protein supplement, or feed for livestock and poultry, and the cellulosic residue has value as a feedstock for a thermochemical process unit, such as for the production of a biofuel.

The present disclosure relates to serine proteases and variants thereof. Compositions containing the serine proteases are suitable for use in cleaning fabrics and hard surfaces, as well as in a variety of industrial applications.
