There is described a process for the production of a polysaccharide-producing enzyme, which comprises fermenting an appropriate enzyme producing organism in aqueous sucrose, characterized in that the sucrose concentration is maintained at between 1 and 10 g/l throughout all but the last part of the fermentation and that the dissolved oxygen content of the fermentation is controlled. There is also described a method for the purification of a polysaccharide producing enzyme, which comprises absorbing a mixture containing the enzyme on an anionic resin and removing the enzyme from the resin with a sugar containing eluant, and a novel highly purified form of polysaccharide producing enzyme. |
