Highly efficient production of 1,3-propanediol by CRISPR-Cas12a-edited Klebsiella pneumoniae using glycerol and lignocellulosic hydrolysate as co-substrates.
Efficient biosynthesis of 1,3-PDO, a key bio-based chemical, depends on precise regulation of the host metabolic network. In this study, a heterologous CRISPR-Cas12a genome editing system was established and systematically optimized in Klebsiella pneumoniae, enabling efficient and stable genome editing (75-100% efficie...
