CRISPR safeguard changes how engineered microbes can be controlled

Engineered microorganisms are widely used in industrial biotechnology and biopharmaceutical applications, including the production of biofuels, sustainable chemicals, and therapeutic compounds. However, concerns remain regarding the unintended environmental release and uncontrolled proliferation of genetically engineered microbes. For this reason, biocontainment technologies, which are designed to prevent microorganisms from surviving outside controlled environments, have become increasingly important in both academia and industry.
