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.
