文摘

•: S. sp. carrying of vgb was constructed to improve welan gum yield.
•: An increase of 34.6 g/L welan gum was attained with VHb expression.
•: The rheological behavior of welan gum solutions had no change after vgb insertion.
•: VHb expression enhanced oxygen uptake rate and ATP level for welan gum production.
