    Study Notes

    Organismi Catalase Positivi

    • Affirmatio vera: Organismi catalase positivi habent enzyma catalasem, quod hydrogenii peroxidum inaquam et oxygenium reducit.
    • Exemplum: Bacteria Escherichia coli est catalase positiva.

    Organismi Catalase Negativis

    • Affirmatio vera: Organismi catalase negativi non habent enzyma catalasem, quod hydrogenii peroxidum inaquam et oxygenium reducit.
    • Exemplum: Bacteria Streptococcus pneumoniae est catalase negativa.

    Organismi non Catalase Positivi

    • Exemplum: Neisseria spp. non est catalase positivus.
