System for RAPID Testing of BIOBURDEN or STERILITY with Automated Imaging

Mango has a technology for detecting microbial growth in hours that is non-destructive of the sample; the electronic Petri dish, or ePetri. This project will update the consumables, design, & software and demonstrate performance of ePetri.

Industry Need

  • While sterility and bioburden testing are essential to the quality control process for biopharmaceuticals, it can often take significant time to generate results. 
  • Pharmaceutical microbiologists and the entire supply chain often must wait from days to weeks for results, creating a bottleneck in biomanufacturing and the release process.  


Mango has an exclusive licensed based technology detecting microbial growth in hours that is non-destructive of the sample: the electronic Petri dish, or ePetri.  

  • ePetri is an automated method for detecting growth and counting individual microorganisms on the surface of an agar-containing plastic consumable. Using sophisticated lenseless image capture and analysis, microbiologists can quickly count micro-colonies emerging from culturable individual microbial cells (i.e., growth-based technology) within a few hours, a full 1 to 3 days sooner than is possible by means of the naked eye.  
  • ePetri uses the same media, filters, plastics, and visual readout that the industry and regulators have trusted for 75 years.  
  • ePetri has the potential to revolutionize how biopharmaceutical bioburden and sterility tests are performed.  

Outcomes and Impacts

Reduce sterility testing time for intermediate monitoring and finished product release

Improve quality control and quality assurance for products that cannot be subjected to in-process sterile filtration
