Researchers at the J. Craig Venter Institute and collaborators found molecular evidence of a marine-derived community of microscopic eukaryotes living near Blood Falls, a striking iron-rich outflow emerging from beneath Taylor Glacier.

JCVI has been awarded a $200,000 Emily Beazley Kures for Kids Fund St. Baldrick’s Research Grant to support Nan Zhu, Ph.D.'s research into a novel dual-action therapy for MLL-rearranged childhood leukemias—

In the final legs of their Tonga expedition, Dr. Garza and the eXXpedition crew partnered with local communities to better understand the sources of marine plastic pollution affecting their islands.

Genetic Markers Remain Detectable in Genetically Engineered Microbes Biocontained with a CRISPR Kill Switch

Biocontainment strategies, such as kill switches, have been developed to avoid the unintended proliferation of genetically engineered microbes (GEMs) intended for open-release environmental applications. However, the presence of GEM DNA after successful biocontainment presents new environmental risks and challenges for monitoring. In this study, we investigated whether biocontainment using a CRISPR-Cas9 kill switch, which causes double-strand breaks in target genes essential for GEM growth, could resolve this challenge in a model Escherichia coli GEM. Surprisingly, the escape rates of the GEM as determined by CRISPR-targeted gene abundances were as high as 10–1.6 to 10–1.0 in LB media, despite the escape rates measured by colony forming units (cfu) being only 10–6.2 under the same condition. This discrepancy suggested that the CRISPR-Cas9 kill switch prevents colony growth while still leaving a large fraction of target genes intact for detection by molecular methods. Within 1 h after biocontainment, these target genes remained predominantly inside an intact cell membrane and were resistant to degradation by DNase, though degradation was observed in river water over multiple days. Overall, a detailed understanding of the impact of the biocontainment mechanism on both the GEM and its DNA is needed to minimize unintended environmental risks.
