Viscometric assay of bacterial alginase

Equations defining the reaction of microbial alginase on commercial sodium alginate are presented with respect to the viscometric assay of enzyme activity. The negative log of K was found to be linearly related to the concentration of algin, where K is defined as the change in the reciprocal of relative viscosity with time. The negative log of K was also found to be linearly related to the amount of enzyme in reaction mixtures when the substrate concentration was held constant.
