The ZymoBIOMICS Microbial Community DNA Standard is designed to assess bias, errors and other artifacts after the step of nucleic acid purification.

• Accurate composition: Composition cross-validated with multiple types of measurements.
• Negligible impurity: Guaranteed to contain < 0.01% foreign microbial DNA.
• Wide range of GC content: 15%-85%, for assessing bias caused by GC content variation.

Theoretical Composition based on Genomic DNA are Listeria monocytogenes - 12%, Pseudomonas aeruginosa - 12%, Bacillus subtilis - 12%, Escherichia coli - 12%, Salmonella enterica - 12%, Lactobacillus fermentum - 12%, Enterococcus faecalis - 12%, Staphylococcus aureus - 12%, Saccharomyces cerevisiae - 2%, and Cryptococcus neoformans - 2%.
