Reactive and sorbent materials including a non-encapsulated crosslinked biological material immobilized on a support matrix that includes a polyamine and at least one support material are described. The support material can be an inorganic or organic support material. The reactive and sorbent materials are formed by reacting the biological material with the polyamine, at least one support material, and a crosslinking agent. The materials exhibit enhanced properties generally, are capable of maintaining their reactive and sorbent properties in contact with digestive fluids, and exhibiting their reactive and sorbent properties as they pass throughout an organism's entire digestive system. Reactive and sorbent materials in contact with digestive juices at pH's ranging from about 3 to about 7 have maintained their reactive and sorbent properties for at least 4 hours.

Reactive and sorbent materials

The present application discloses immobilized enzymes and immobilized enzyme materials comprising a crosslinked enzyme having a support material which includes a biomass material different than the biomass used to initially derive the enzyme. Optionally, the immobilized enzyme further includes a polymeric material and/or the biomass which was used to initially derive the enzyme. The resulting immobilized enzyme materials may be biodegradable. The present application also discloses methods of making and using the disclosed immobilized enzyme materials.

Desorption process and apparatus

A process for treating a liquid comprising subjecting a liquid containing, in solution, citric acid as well as a less desirable component having a similar molecular weight to citric acid, to nanofiltration in a filtration step. From the filtration step, a permeate in which the ratio of the concentration of the citric acid to that of the less desirable component is greater than the ratio of the concentration of the citric acid to that of the less desirable component in the solution, is obtained.

Method for synthesizing L-2-oxothiazolidine-4-carboxylate and its acid, L-2-oxothiazolidine-4-carboxylic acid. The present invention involves the separation of phenol from a reaction mixture containing L-2-oxothiazolidine-4-carboxylate and phenol. In the present method a reaction mixture containing phenol, L-2-oxothiazolidine-4-carboxylate, and chloride salt, is contacted with a phenol adsorbing adsorption resin, the adsorption resin comprising a polymer having a polyethylene backbone. The adsorption resin is capable of adsorbing substantially all of the phenol while not adsorbing substantial amounts of the L-2-oxothiazolidine-4-carboxylate from the reaction mixture.

A process which permits the facile conversion of green bananas to a sugar syrup uses a sequence of steps involving grinding the bananas, heating the bananas, treating the bananas with an alpha amylase to convert the starch granules into lower molecular weight molecules (liquefaction), changing conditions and treating the low molecular weight starch molecules and other substances in the liquefied fluid with the enzymes, amyloglucosidase, pectinase, cellulase, macerase, etc., filtering the resultant fluid to remove the solids, and, if necessary, evaporating the sugar solution to a suitable concentration. Use of elevated pH in each of the enzymatic conversion steps was found to greatly increase the glucose yield.
