Maltose phosohorylase, trehalose phosphorylase, Plesiomonas strain and preparation process of trehalose

摘要

Disclosed are a novel microorganism (FERM BP-5144) belonging to the genus Plesiomonas and having ability to produce maltose phosphorylase and trehalose phosphorylase required for the enzymatic production of trehalose and novel maltose phosphorylase and trehalose phosphorylase obtainable from the microorganism as well as a process for producing the enzymes. A novel process for enzymatically producing trehalose (O- alpha -D-glucopyranosyl-(1->1)-D-glucopyranoside) is also disclosed.
