Advancements in Microbial Customization
Scientists at the Department of Energy’s Oak Ridge National Laboratory (ORNL) have introduced a groundbreaking software called MIJAMP. This tool significantly accelerates the process of customizing microbes, reducing the time needed for this critical task from a week to just a few hours.
The MIJAMP software specifically focuses on detecting patterns of methylation in DNA sequences, which act as on/off switches for genes. These chemical modifications greatly influence microbial growth, defense against viruses, and the inclusion of new genetic material. Methyl groups signal enzymes to ignore parts of DNA that have these markers, complicating the researchers’ efforts to introduce new genetic material into microbes.
To overcome these challenges, MIJAMP employs outputs from synthetic biology tools, particularly nanopore sequencing data. This enables the identification of DNA segments marked with methyl groups. By leveraging pattern recognition algorithms, MIJAMP informs scientists about which regions of the microbial genome contain these protective methyl markers. This foresight allows researchers to design interventions that bypass the microbes’ defense systems effectively.
The innovative software was detailed in the Journal of Industrial Microbiology and Biotechnology and is available as open-source on ORNL’s Gitlab, promoting wider accessibility and potential collaborative improvements. One of MIJAMP’s standout features is its “human-in-the-loop” approach, which allows for validation of predictions, addressing the unpredictable nature of biological data.
In practical applications, MIJAMP was successful in uncovering methylated motifs across various naturally isolated microbial strains and modified bacteria. By pinpointing the exact DNA methylation patterns, scientists can replicate these configurations when modifying microbial DNA, thereby minimizing defense mechanisms that could impede progress.
Project lead Bill Alexander from ORNL’s Synthetic Biology Group emphasized that “the greatest impact is expediting the domestication of non-model microbes for specific, efficient functions.” A task that previously required substantial time and computational resources can now be completed in a fraction of the time using a standard laptop.
MIJAMP is built on prior methods developed by ORNL and other institutions as part of the DOE Center for Bioenergy Innovation. Its core aim is to facilitate the acceptance of foreign DNA in non-model microbes, enhancing their beneficial traits for biomanufacturing.
This initiative contributes to a larger range of computational tools designed at ORNL to advance bioeconomy research, automating certain synthetic biology tasks and fostering biotechnology advances. Such innovations not only support energy security but also enhance the United States’ competitiveness in the global landscape.
The development of MIJAMP received backing from the DOE Office of Science’s Biological and Environmental Research programs, alongside collaboration from the DOE Bioenergy Technologies Office’s Agile BioFoundry consortium, which bridges partnerships between national labs and industry.
In summary, MIJAMP represents a significant leap in synthetic biology, paving the way for enhanced microbial customization and biomanufacturing applications.
