Enhancement of Biodesulfurization in Two-Liquid Systems by Heterogeneous Expression of <i>Vitreoscilla</i> Hemoglobin

Abstract

The vgb gene, encoding Vitreoscilla hemoglobin (VHb), was introduced into a specific desulfurization bacterium, Rhodococcus erythropolis LSSE8-1. The VHb-specific spectrum was observed for the recombinant. Compared to the wild type, the strain bearing vgb showed a higher biomass yield and desulfurizing activity.
