Enzyme assays are used to measure the level of enzymatic activity in a sample and are vital for the study of enzyme kinetics and inhibition. Based on the level of enzyme inhibition, the assays identify different bacteria strains through easy-to-read indicators such as changes in colour, turbidity, sedimentation, precipitation, and colourful formations. The presence or absence of enzyme activity is a taxonomic property of microorganisms and can be used for differentiation or identification.

Catalasi reagente

Supplier: VWR Chemicals

Il test di catalasi permette di differenziare o identificare microrganismi verificandone la capacità di produrre catalasi, un enzima che proteggere i microorganismi dai metaboliti tossici dell'ossigeno. Generalmente solo i microorganismi aerobi producono catalasi.

EnteroPluri test

Supplier: LIOFILCHEM

EnteroPluri Test is a 12-sector system containing special culture media that permits identification of the Enterobacteriaceae and other gram negative, oxidase negative bacteria. The system allows the simultaneous inoculation of all media present in the sectors and the execution of 15 biochemical reactions. Microorganism is identified evaluating the colour change of the different culture media after 18 to 24 hours of incubation at 36 ±1 °C and by a code number obtained from biochemical reaction interpretation. Oxidase, Kovacs Reagent Indol (e.g. 1.00181.0002, 1.09293.0100, 1.11350.0001) and Codebook are not included.
