Beschreibung

Allgemeine Beschreibung

Citrobacter freundii CECT^® 401 Vitroids are Certified Microorganisms Standards (Certified Microbiological Reference Materials) that can be used as quantitative and qualitative control organisms. They contain colony forming units (CFUs) in the range of 130-300 CFU per disc. The technology allows long-term conservation and renders the organisms resistant to temperature changes. They are intended to be used as daily internal quality control organisms. These microorganisms are certified according to ISO/IEC 17025 and produced under reproducible conditions compliant with ISO 17034 using authenticated strains from CECT^®. These ready-to-use microbiological controls minimize the need for maintaining control strains in the test laboratory and guarantee the use of an authenticated control culture for every quality control test. Vitroids are derived from a traceable culture obtained freeze-dried from CECT^®.

Anwendung

Citrobacter freundii CECT^® 401 Vitroids are used as reference strains in routine quality controlfor food, beverage, water, and environmental testing. Additionally, they areexcellent for use in method development and validations, as starter cultures, and for research studies and educational purposes.
