Different from conventional uricase products, the uricase of the present invention has outstandingly high thermal stability and is active in a wide range of pH from 5 to 10 for the oxidative decomposition of uric acid undertaken in clinical analysis. The uricase of the invention is produced microbiologically by a thermophilic microorganism belonging to the genus of Bacillus and especially named as Bacillus sp. TB-90 which is a novel species distinguishable from any of the microorganisms belonging to the genus of Bacillus.

Uricase and a method for the preparation thereof

Different from conventional urease products, the urease of the present invention has excellent stability, and has a smaller Km value. The urease of this invention is produced microbiologically by a thermophilic microorganism belonging to the genus of Bacillus and especially named as Bacillus sp. TB-90 which is a novel species distinguishable from any of the microorganisms belonging to the genus of Bacillus.

A process for the preparation of maltopentaose is disclosed, comprising cultivating a maltopentaose-producing microorganism belonging to a genus Bacillus in a medium and isolating the thus-accumulated maltopentaose from the culture broth. A typical example of the maltopentaose-producing microorganism is Bacillus cereus NY-14. This process permits the preparation of maltopentoase without the use of amylase as in conventional methods. Maltopentaose is useful, for example, as a substrate for the determination of serum amylase.
