Microbial Strain Library

A collection of 40,000 distinct strains from bacterial and fungal genetic sources.

Key features:

  • World leading collection of fungal and bacterial genetic sources
  • 40,000 distinct strains:
    – 30,600 bacterial cultures
    – 9,400 fungal cultures
  • Include identified producer strains for 2,559 different microbial metabolites:
    – 1,208 bacterial metabolites
    – 1,316 fungal metabolites
    – 35 metabolites



The IMAX Discovery database contains biological activity data derived from testing the NatPure, the PreFrac and Advanced Extracts libraries against more than 200 targets on various biochemical and cellular assays.
Bioprofiling can be used to address the initial phases of starting projects as well as support the results of more advanced projects.

Key features:

  • History of over 200 projects
  • Over 12 Million data points
  • References from the world’s largest collection of Natural Products

Synthetic compound collection, AXXDIV4.0

Besides the access to the natural compound collection, IMAX Discovery offers an entirely new generation screening collection composed of 325,000 synthetic compounds, carefully selected on the basis of Axxam’s broad screening expertise and with significant input from the company’s team of medicinal and computational chemists.
The AXXDIV4.0 library is not focused on a specific target class or chemical space built around a target class
but is rather diverse and meant to explore the highest diversity possible.
The compounds have been selected to be novel (available on the market for less than 6 years)
and multiple filters were applied in the selection process to exclude undesirable features.
