520 3 |a 4-Hydroxyisoleucine (4-HIL) is a nonproteinogenic amino acid that exhibits insulinotropic biological activity. Here, L-isoleucine dioxygenase gene (ido) derived from Bacillus thuringiensis YBT-1520 was cloned and expressed in an L-isoleucine-producing strain, Corynebacterium glutamicum ssp. lactofermentum SN01, in order to directly convert its endogenous L-isoleucine (Ile) into 4-HIL through single-step fermentation. The effects of corn steep liquor limitation as well as ido and truncated idoΔ6 overexpression on 4-HIL production were researched. 4-HIL production by ido-overexpressing strain was improved to 65.44 ± 2.27mM after fermented for 144h under corn steep liquor-subsufficient condition, obviously higher than that under corn steep liquor-rich and insufficient conditions. The conversion ratio of Ile to 4-HIL increased to 0.85mol/mol. In addition, 4-HIL production by ido-overexpressing strain was higher than that by idoΔ6-overexpressing strain, in accord with the relatively higher affinity of Ido as compared to IdoΔ6. This research generated a novel system for 4-HIL de novo biosynthesis and demonstrated corn steep liquor limitation as a useful strategy for improving 4-HIL production in recombinant C. glutamicum ssp. lactofermentum.
