Vibrio natriegens is a gram-negative bacterium, which has received increasing attention due to its very fast growth with a doubling time of under 10 min under optimal conditions. To enable a wide range of projects spanning from basic research to biotechnological applications, we developed NT-CRISPR as a new method for genome engineering. This book chapter provides a step-by-step protocol for the use of this previously published tool. NT-CRISPR combines natural transformation with counterselection through CRISPR-Cas9. Thereby, genomic regions can be deleted, foreign sequences can be integrated, and point mutations can be introduced. Furthermore, up to three simultaneous modifications are possible.

摘要

Vibrio natriegens is a gram-negative bacterium, which has received increasing attention due to its very fast growth with a doubling time of under 10 min under optimal conditions. To enable a wide range of projects spanning from basic research to biotechnological applications, we developed NT-CRISPR as a new method for genome engineering. This book chapter provides a step-by-step protocol for the use of this previously published tool. NT-CRISPR combines natural transformation with counterselection through CRISPR-Cas9. Thereby, genomic regions can be deleted, foreign sequences can be integrated, and point mutations can be introduced. Furthermore, up to three simultaneous modifications are possible.
