Bacillus subtilis has become the primary bacterium model for basic research and biotechnology, and it has been studied for over 40 years, mainly in genetics. However, we couldn’t find many illustrations or outreach articles about this organism. So we had to do it ourselves! In this infographic we show how Bacillus subtilis is one of the main candidates to become the best mini-factory for producing proteins of interest and fine chemicals. Systems and synthetic biology approaches could make it unbeatable!
