Abstract: The hemoglobin from the bacteriumVitreoscilla(VHb) is the firstmicrobial hemoglobin, which has been extensively studied with respect to its structure, biochemical functions, and the mechanisms by which itsexpression is controlled. Expressing VHb in a variety of heterologous hostsresults substantial increasesin production of a variety of useful products(antibiotics, proteins, polymersetc.), host resistance andability to degrade some harmful compounds, by promoting oxygen transport to enhance respiratory and energy metabolism. So this paper reviewed on the function and structure of VHb and the improving output of microbial metabolites, some characteristics of plants and animals and influence of the application of bioremediation capability. And we discussed about the application prospect and development space in the metabolism of plant and animal.

Key words: Vitreoscillahemoglobin, bioproduct, production metabolite, bioreme diation, fermentation
