The Bacillus subtilis system was developed as a host for gram-positive bacteria in a variety of applications, including agricultural, medical and food biotechnology and the production of recombinant proteins.
The Bacillus subtilis system is advantageous in that it is non-pathogenic, does not have significant bias in codon usage, and is capable of secreting functional extracellular proteins directly into the culture medium. A large body of information concerning transcription, translation, protein folding and secretion mechanisms, genetic manipulation, and large-scale fermentation is available.
Multiple Bacillus subtilis strains are offered:
  • 1012 wild type (PBS020) – for intracellular expression
  • 168 Marburg (PBS021) – for intracellular expression
  • WB800N (PBS022) – for secretion vectors; carries resistance to neomycin
  • AS1 (PBS026) - for enhancing solubility of intracellular proteins
Please note these products require a license for non-academic institutions. Please contact us for licensing information.
