Information on the Microbiologics Enumerated Lyophilised Microorganism Preparations
Go to Microbiologics website
Microbiologics® specialises in producing lyophilised reference stock cultures for quality control laboratories. Ready-to-use reference stock cultures will alleviate labour-intensive processes of preparing, storing, and maintaining in-house cultures.

Each lyophilised microorganism is no more than four passages from the reference culture and is authentic and traceable. Microorganism strains are derived from well-known culture collections from around the world including ATCC®, NCIMB, NCTC and more.

Here you will find information on the range of Enumerated Microorganism Preparations (products which are derived from a reference culture and are produced to a predetermined assay value)
.

These microorganism preparations are commonly used in the following industries:
 
  Food and Beverage
  Pharmaceutical
  Cosmetic
  Dietary Supplements and Nutraceuticals
