CRISPR/Cas12a Mediated Genome Editing To Introduce Amino Acid Substitutions into the Mechanosensitive Channel MscCG of Corynebacterium glutamicum.

ABSTRACT: Against the background of a growing demand for the implementation of environmentally friendly production processes, microorganisms are engineered for the large-scale biosynthesis of chemicals, fuels, or food and feed additives from sustainable resources. Since strain development is expensive and time-consuming, continuous improvement of molecular tools for the genetic modification of the microbial production hosts is absolutely vital. Recently, the CRISPR/Cas12a technology for the engineering of Corynebacterium glutamicum as an important platform organism for industrial amino acid production has been introduced. Here, this system was advanced by designing an easy-to-construct crRNA delivery vector using simple oligonucleotides. In combination with a C. glutamicum strain engin
