Cultural Conditions for the Microbial Production of β-Tyrosinase and Tryptophanasedegradation of L-tyrosine and L-tryptophan, and require pyridoxal 5’-phosphate (PLP) as a cofactor. Crystalline preparations of these enzymes were prepared in our laboratories from . and ., and their properties were established in some detail. The crystalline enzymes were shown to catalyze a variety

Aqueous Two-Phase Systems for the Large-Scale Purification of Enzymesmes still resembles normal laboratory procedures, only made larger. For the first steps in isolation, where large quantities and volumes are involved, new processes are particularly needed with the potential for easy scale up and continuous processing under conditions which favor the stability of th

Immobilized Lactase for Whey Hydrolysis: Stability and Operating Strategystimates (1,6,7), it is apparent that one of the most critical factors in determining the cost of hydrolysis is the stability of the immobilized enzyme (IME) in actual use. Although some data are available concerning immobilized lactase stability as a function of feed composition (7), they are not e

Economical Aspects of Continuous Operation with Biocatalysisecome an interesting alternative to continuous operation with covalently bound enzymes even on an industrial scale. Continuous operation has been studied with native and carrier-fixed acylase used for optical resolution of methionine by stereospecific hydrolysis of N-acetyl-D,L-methionine (1,2). In

Membrane Reactor-Separator for Continuous Enzymatic Regeneration of ATPre the input of chemical energy usually in the form of ATP; but a continuous supply of ATP at current prices would make such reactions prohibitively expensive. During the reaction ATP is degraded to ADP or AMP. We have shown previously (2-4) that it is economically feasible to use cell-free enzymati
