The ZymoBIOMICS Microbial Community Standard is designed to assess bias and errors in the extraction methods of a microbiomics workflow.

• Microbiome standard: Mock microbial community of well-defined composition.
• Identify bias: Contains both tough-to-lyse and easy-to-lyse organisms.
• Accurate characterization: Ideal for validation, optimization, and quality control of complete microbiome workflows.

The Microbial Community Standard mimics a mixed microbial community of well-defined composition, containing three easy-to-lyse Gram-negative bacteria, five tough-to-lyse Gram-positive bacteria, and two tough-to-lyse yeasts.

Acting as a defined input from the beginning, the Microbial Community Standard can guide construction and optimization of entire workflows and can also be used as a routine quality control.
