[Rational organization of the technological processes of hydrolyzing whey lactose in the presence of a heterogeneous fiber biocatalyzer].

We have studied lactose hydrolysis in whey in the presence of a fibrous biocatalyst containing immobilized beta-galactosidase in a continuous-flow column reactor, and in a reactor unit with substrate recycling in batch and continuous regimes. The comparative study of the efficiency of the reactors allowed us to recommend the reactor unit with substrate recycling for lactose hydrolysis in whey in the batch regime, since it provides both satisfactory hydrodynamic stability and high productivity.
