摘要:
A new enzyme, aldehyde oxidase, catalyses the oxidation of an aldehyde to a corresponding acid but does not have any catalytic action upon other substrates, particularly nitrogen-containing aromatic heterocyclic compounds, purine, hypoxanthine and quinine. The enzyme is produced by fermentation. A biologically pure culture of the microorganism Pseudomonas sp. No. 6233, FERM P-6467, which produces recoverable quantities of aldehyde oxidase when cultured, is another embodiment of the present invention.
摘要:
A process is disclosed for producing orotic acid, the process involves culturing in a medium a microorganism of the genus Corynebacterium which is capable of producing orotic acid and has resistance to a pyrimidine analogue or to both a pyrimidine analogue and a sulfa drug, until orotic acid is accumulated in the culture, and recovering orotic acid therefrom.

摘要:
Thermophilic aspartase is produced by culturing a microorganism belonging to the genus Bacillus. The enzyme is useful as a catalyst in the production of L-aspartic acid from ammonium fumarate or a mixture of fumaric acid and ammonia. A biologically pure culture of Bacillus thermoaminophilus and/of Bacillus aminogenes is produced.
