The invention is a process for producing N-substituted glucamines, a process for oxidizing an N-substituted glucamine with an oxidizing microbe or extract thereof, and a process for oxidizing an N-substituted glucamine with an oxidizing microbe or extract thereof and reducing the oxidized N-substituted glucamine to an N-substituted-1-deoxynojirimycin. In addition, a one pot process for producing N-substituted-1-deoxynojirimycin from -glucose is disclosed.

The invention is a process for producing N-substituted glucamines, a process for oxidizing an N-substituted glucamine with an oxidizing microbe or extract thereof, and a process for oxidizing an N-substituted glucamine with an oxidizing microbe or extract thereof and reducing the oxidized N-substituted glucamine to an N-substituted-1-deoxynojirimycin. In addition, a one pot process for producing N-substituted-1-deoxynojirimycin from D-glucose is disclosed.

Process for microbially oxidizing N-substituted glucamines

A process for producing N-substituted amino compounds, a process for oxidizing an N-substituted amino compound with a microbe, or cell fragment or cell free extract thereof, and a process for oxidizing an N-substituted amino compound with a microbe, or cell fragment or cell free extract thereof and reducing the oxidized N-substituted amino compound to N-substituted-polyhydroxy piperidines based on N-substituted mannosamines, allosamines and altrosamines, N-substituted polyhydroxy pyrrolidines, and N-substituted polyhydroxy azetidines. In addition, a one pot process for producing N-substituted-polyhydroxy piperidines based on N-substituted mannosamines, allosamines and altrosamines, N-substituted polyhydroxy pyrrolidines, and N-substituted polyhydroxy azetidines from the respective sugar is disclosed. A second embodiment comprises novel compositions of N-substituted-amino-6-deoxy-2-ketohexuloses based on mannose, allose and altrose, N-substituted-amino-5-deoxy-2-ketopentuloses and 4-(N-substituted)-amino-1,3-dihydroxy-2-butanones.

Immunologically intact protein or peptide immunogens are recovered from vaccines consisting of immunogen-aluminum hydroxide (alum) complexes. Recovery consists of dissolution of the complexes with an alkali metal salt of a carboxylic acid at a basic pH, reduction of the pH to physiological levels, removal of excess dissolvent and isolation of the protein or peptide immunogen.

Use of a static mixing system element as a tissue culture propagator. The element comprises an assembly of parallel sheets shaped to provide a plurality of mixing cells wherein fluid entering a cell from two separate inlet channels is rearranged due to shearing and extensional forces and divided into two new outlet streams each of which leaves the mixing cell in a different direction from either inlet stream. The configuration of the device provides uniform flow across all surfaces for precise control of growth conditions and maximum cell growth.

Ethylcellulose walled microcapsules, obtained from cyclohexane medium are heavily solvated with cyclohexane and tend to form lumps even after drying. Displacements of cyclohexane by pentane, hexane, heptane or octane or mixtures thereof during the isolation of the microcapsules gives a dry product which is essentially all discrete dry microcapsules.
