Microbial contamination testing in biopharmaceutical manufacturing
The biopharmaceutical industry is working towards automating the entire manufacturing workflow (Pharma 4.0), where real-time data and artificial intelligence will maximize manufacturing efficiency.
To achieve Pharma 4.0, it is critical to have automated in-process microbial testing, yet no technology is currently meeting the industry’s needs.
This provides an exceptional opportunity for MantaBio Life Sciences and the MiQLab® System.
The biopharmaceutical manufacturing process has significant risks of microbial contamination. The inability to identify a contamination early in the process can result in:
- Loss of product
- Loss of manufacturing time
- Extensive cleaning
- Lost revenue
Larger Bioreactors = Increased Contamination Incident Risk and the Potential Cost of an Incident
For example, a leading global biopharmaceutical company was fined $175M by the FDA for releasing contaminated product and the impact to the company was likely $100’s of millions more.1
Every major manufacturer has to deal with contamination incidences, but since most are caught before product is released – notification of these incidences never make it into the public domain. Nonetheless, contaminations remain a significant and costly problem for the industry.
Two leading biopharmaceutical manufacturers purchased MantaBio’s MiQLab System and successfully completed feasibility studies. Following these studies, they expressed interest in a system specifically designed for the industry that meets its requirements.
Fortunately, many of the advantages of the 1st generation MiQLab System can be leveraged in the design of the 2ndgeneration system. This minimizes risk, will speed development work, and will shorten the time to product launch.
Rapid Screening
Our MiQLab System is an automated, PCR system that allows users to test for numerous contaminants onsite, returning results in ~2 hours.

Next Generation Biomanufacturing
Shifting towards the next era of biomanufacturing stands as a top priority for the industry, and in-process microbial testing will play a pivotal role.
Biopharma companies are steadily moving toward intensified, continuous, and automated production of biologics, often referred to as “biopharma 4.0”.
The 4.0 transformation relies on advanced instrumentation, including process analytical technology, or PAT, to achieve this objective.
4.0 PAT must enable testing at-line (requires sampling but enables faster turnaround time), on-line (connected to the process line), or in-line (fully integrated into the line). MantaBio’s 2nd generation MiQLab™ System is intended to first be used in near-line settings. As the technology matures, the goal is to move the technology to at-line environments.
A full industry shift will take a number of years, but forward-looking companies have a persistent interest in adopting advanced technology to enable this transformation.
While 4.0-capable analytical techniques are already being implemented to evaluate the properties of a drug itself, 4.0-compatible tools for microbial testing remain a bottleneck and present a compelling opportunity for MantaBio Life Sciences.
- PCR Testing in Biopharmaceutical Manufacturing
PCR is in the early stages of adoption. The vast majority of PCR is performed off-site at specialized laboratories.
Current microbial testing is owned by Quality Control. The breakdown of tests performed is shown below.
- Release Testing 10%
- In-Process Testing 20%
- Environmental Testing 70%
Final Release Testing (“sterility” testing) is tightly regulated while in-process testing (“bioburden”) data is considered by regulators but less tightly controlled. Some companies hold product while waiting for in-process test results, while others will proceed “at risk” before results are returned.
- Microbial Testing Process
In-process microbial testing involves multiple sampling points along the process.
- What We Test For
Bacteria and fungi are key in bioburden testing, while mycoplasma and viruses are vital in sterility testing.
Bacteria
- Most common contaminant
- Primary focus of most bioburden testing, likely to be most frequent, highest test volume
Fungi
- Similar to bacteria, typically tested for at the same testing points
- Routinely tested for in bioburden testing
Mycoplasma
- Difficult and time-consuming to culture for detection using traditional methods
Viruses
- Extremely small, difficult to detect
- Generally specific to host cell type
- Genome is not highly conserved
- MiQLab System Key Advantages Over Competing Technologies

During biopharmaceutical manufacturing, routine microbial contamination screening is essential to ensure a safe product and to maintain manufacturing efficiency.
Within any large biopharmaceutical company, there are multiple departments beyond manufacturing that can benefit from MantaBio’s technology, including: R&D, Process Development, Analytical Development, Process Analytical Technologies, & QA/QC
