Foams having aspartase-producing microorganisms bound to the foam are made from polyurethane prepolymers which are capped with polyisocyanates, including diisocyanates, derived from methylene-bis (phenyl isocyanate) which is commonly known as MDI. These MDI based foams are hydrolysis resistant as compared to the previously used TDI based foams. The foams can be used to produce L-aspartic acid unde...

There is disclosed a process for producing a dispersion of a phenolic resin in water by mixing a pre-formed, solid, substantially water-insoluble, phenolic resin with water, an organic coupling solvent, and polyvinyl alcohol. The resulting dispersions are especially useful in coatings applications.
