Abstract: The invention relates to a process for the isolation of an organic amine from a composition comprising the organic amine and an acid, or a salt of the organic amine and the acid, wherein the process comprises steps wherein ammonia or hydrazine is added to the composition thereby forming a multi-phase system comprising an organic amine-rich phase and an acid-rich phase, the organic amine-rich phase and the acid-rich phase obtained in step (i) are separated, and the organic amine is isolated from the organic amine-rich phase.

Abstract: The present invention relates to a novel process for the preparation of cephalosporins having been deacylated at the 7-amino group, by fermentation of a cephalosporin producing microorganism in the presence of a side chain precursor, extraction of the N-substituted cephalosporin compound as present in the fermentation broth or fluid to an organic solvent, back extraction of the N-substituted cephalosporin compound to water, treatment of the aqueous phase with a dicarboxylate acylase and isolation of the crystalline cephalosporin compound according to formula (1) from the conversion solution, characterized in that the fermentation broth or fluid is incubated at acidic conditions and an elevated temperature prior to extraction of the N-substituted cephalosporin compound to an organic solvent.

Abstract: An immobilized enzyme preparation is disclosed which comprises a gelling agent which has been cross-linked and active carbon in an amount of 1 to 3%. The gelling agent may be egg white chitosan or alginate. The enzyme glucose isomerase may be employed. When used in packed bed columns in enzymatic glucose isomerization processes, the disclosed immobilized enzyme formulation allows for a bedheight that is twice as high, a syrup flow that is doubled, or a doubled syrup viscosity when compared to formulations without carbon.
