additional information CRISPR-Cpf1-assisted engineering of Corynebacterium glutamicum SNK118 for enhanced L-ornithine production by NADP-dependent glyceraldehyde-3-phosphate dehydrogenase and NADH-dependent glutamate dehydrogenase. Insufficient intracellular NADPH content has been recognized as a limiting factor in L-ornithine biosynthesis. Overexpression of NADP-dependent glyceraldehyde 3-phosphate dehydrogenase gene CsgapC from Clostridium saccharobutylicum strain DSM 13864 and NADH-dependent glutamate dehydrogenase gene BsrocG from Bacillus subtilis strain HB-1 results in markedly increased ornithine biosynthesis. The engineered Corynebacterium glutamicum strain KBJ11 (SNK118DELTAargRDELTAargFDELTAncgl2228/pXMJ19-CsgapC-BsrocG) is constructed for L-ornithine overproduction. In fed-batch fermentation, L-ornithine of 88.26 g/l with productivity of 1.23 g/l/h (over 72 h) and yield of 0.414 g/g glucose is achieved by strain KBJ11 in a 10-l bioreactor. High titer and yield of L-ornithine production by microbial fermentation proves that heterologous expression of CsgapC and BsrocG can promote L-ornithine production by Corynebacterium glutamicum strains Clostridium saccharobutylicum
