Examples of Strain development programmes

Below is a selection of microorganisms and their respective natural products for which Novacta scientists successfully optimised production.

  • Actinoplanes sp. - lantibiotics
  • Streptomyces citricolor - aristeromycin
  • Streptomyces sp. - carbapenems
  • Streptomyces sp. - milbermycin endectocide
  • Amycolatopsis orientalis - vancomycin
  • Sordaria araneosa -sordarin titre improvement / biosynthetic mutants
  • Phoma sp - squalestatin 

Example

  • Conventional mutagenesis on spores (UV, MNNG)
  • Mutagenized colonies screened in 96-well microtitre plates (biosynthetic mutants) and miniaturised culture vessels (titre improvement)
  • Plates loaded directly onto HPLC, <2 minute mini column
  • Mutants obtained:
     - Block in diterpene (no product)
     - Aglycone
     - Sugar alterations - 100kg batches of modified product
     - Improved titre to commercial production scale
