Background
- Streptomyces are crucial for producing antibiotics and bioactive compounds.
- Current genetic engineering methods for Streptomyces are slow and labor-intensive.
- CRISPR technology has improved access to Streptomyces' metabolic potential, but transformation remains a bottleneck.
Purpose Of The Study
- To present a semi-automated, medium-throughput workflow for introducing recombinant DNA into Streptomyces species.
- To enhance the accessibility of genetic engineering protocols for Streptomyces.
- To validate the efficiency and scalability of the automated workflow.
Main Methods
- Utilized the Opentrons (OT-2) robotics platform for semi-automated DNA transformation.
- Developed ActinoMation, an open-source Python-based protocol creator in Jupyter Notebook.
- Validated the workflow by transforming Streptomyces coelicolor, S. albidoflavus, and S. venezuelae with specific plasmids.
Main Results
- Achieved varying conjugation efficiencies across different Streptomyces strains and plasmids, with notable success in S. venezuelae (up to 6.13%).
- Demonstrated a false positive rate ranging from 8.33% to 54.54%.
- Confirmed that automation streamlines the conjugation workflow without compromising efficiency for large-scale applications.
Conclusions
- The semi-automated workflow using Opentrons and ActinoMation significantly improves the efficiency of genetic engineering in Streptomyces.
- This approach makes complex genetic manipulation more accessible, accelerating the discovery of novel bioactive compounds.
- The developed protocol is scalable and maintains conjugation efficiency, facilitating broader research and development in Streptomyces.
