Abstract
Abstract Incubation of a solution containing d-galactose and a high concentration of sucrose in the presence of α-d-galactosidase from M. vinacea afforded raffinose and planteose in a ratio of∼ 3: 2. On the other hand, circulation of a solution of d-galactose and sucrose through a reaction system consisting of columns, in series, of immobilized α-d-galactosidase and activated carbon gave only raffinose, eluted from the activated carbon column in a ...
