Enhanced production of α-ketoglutarate by fed-batch culture in the metabolically engineered strains of Corynebacterium glutamicum

Abstract The fed-batch culture system was employed to enhance production of α-ketoglutarate (α-KG) by the strainsof Corynebacterium glutamicum, whose genes encoding the key enzymes responsible for the biosynthesis of L-glutamate from α-KG were deleted. In a shake flask fermentation, C. glutamicum JH...

520			\|a Abstract The fed-batch culture system was employed to enhance production of α-ketoglutarate (α-KG) by the strainsof Corynebacterium glutamicum, whose genes encoding the key enzymes responsible for the biosynthesis of L-glutamate from α-KG were deleted. In a shake flask fermentation, C. glutamicum JH110 in which the 3 genes, gdh (encoding glutamate dehydrogenase), gltB (encoding glutamate synthase), and aceA (encoding isocitrate lyase) were disrupted showed the highest production of α-KG (12.4 g/L) compared to the strains JH102 (gdh mutant), JH103 (gltB mutant), and JH107 (gdh gltB double mutant). In the fed-batch cultures using a 5 L-jar fermenter, the strain JH107 produced more α-KG (19.5 g/L), but less glutamic acid (23.3 g/L) than those produced by the parent strain HH109, as well as JH102. The production of α-KG was significantly enhanced and the accumulation of glutamicacid was minimized by the ammonium-limited fed-batch cultures employing C. glutamicum JH107. Further improvement of α-KG production by the strain JH107 was achieved through the ammonium-limited fed-batch culture with the feeding of molasses, and the levels of α-KG and glutamic acid produced were 51.1 and 0.01 g/L, respectively.

In a shake flask fermentation, C. glutamicum JH110 in which the 3 genes, gdh (encoding glutamate dehydrogenase), gltB (encoding glutamate synthase), and aceA (encoding isocitrate lyase) were disrupted showed the highest production of α-KG (12.4 g/L) compared to the strains JH102 (gdh mutant), JH103 (gltB mutant), and JH107 (gdh gltB double mutant). In the fed-batch cultures using a 5 L-jar fermenter, the strain JH107 produced more α-KG (19.5 g/L), but less glutamic acid (23.3 g/L) than those produced by the parent strain HH109, as well as JH102. The production of α-KG was significantly enhanced and the accumulation of glutamicacid was minimized by the ammonium-limited fed-batch cultures employing C. glutamicum JH107. Further improvement of α-KG production by the strain JH107 was achieved through the ammonium-limited fed-batch culture with the feeding of molasses, and the levels of α-KG and glutamic acid produced were 51.1 and 0.01 g/L, respectively.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">α-ketoglutarate</subfield><subfield

title_auth	Enhanced production of α-ketoglutarate by fed-batch culture in the metabolically engineered strains of Corynebacterium glutamicum
abstract	Abstract The fed-batch culture system was employed to enhance production of α-ketoglutarate (α-KG) by the strainsof Corynebacterium glutamicum, whose genes encoding the key enzymes responsible for the biosynthesis of L-glutamate from α-KG were deleted. In a shake flask fermentation, C. glutamicum JH110 in which the 3 genes, gdh (encoding glutamate dehydrogenase), gltB (encoding glutamate synthase), and aceA (encoding isocitrate lyase) were disrupted showed the highest production of α-KG (12.4 g/L) compared to the strains JH102 (gdh mutant), JH103 (gltB mutant), and JH107 (gdh gltB double mutant). In the fed-batch cultures using a 5 L-jar fermenter, the strain JH107 produced more α-KG (19.5 g/L), but less glutamic acid (23.3 g/L) than those produced by the parent strain HH109, as well as JH102. The production of α-KG was significantly enhanced and the accumulation of glutamicacid was minimized by the ammonium-limited fed-batch cultures employing C. glutamicum JH107. Further improvement of α-KG production by the strain JH107 was achieved through the ammonium-limited fed-batch culture with the feeding of molasses, and the levels of α-KG and glutamic acid produced were 51.1 and 0.01 g/L, respectively. © The Korean Society for Biotechnology and Bioengineering and Springer-Verlag Berlin Heidelberg 2013
