Growth Inhibition by Glucose Oxidase of Selected Organisms Associated With the Microbial Spoilage of Shrimp (Pandalus jordani): In Vitro Model Studies

Abstract

The effect of glucose oxidase (GOX)-catalase with different GOX-catalase ratios and of the Chemicals produced by GOX, gluconic acid and hydrogen peroxide, were evaluated on four microorganisms usually present in shrimp. Growth inhibition was independent of the enzyme ratio within the limits tested. Hydrogen peroxide inhibited Pseudomonas fluorescens, Hansenula polymorpha and Acinetobacter calcoaceticum. Only Corynebacter aquaticum was inhibited by gluconic acid but was not affected by hydrogen peroxide.
