|1. (WO2018005655) METHODS FOR GENERATING A BACTERIAL HEMOGLOBIN LIBRARY AND USES THEREOF|
|Title:||METHODS FOR GENERATING A BACTERIAL HEMOGLOBIN LIBRARY AND USES THEREOF|
The present disclosure describes methods for generating microbial strains expressing a heterologous bacterial hemoglobin gene that produce biomolecules of interest. In aspects, the disclosure provides novel bacterial strains, which express a heterologous bacterial hemoglobin gene whose expression is controlled by a native Corynebacterium glutamicum promoter or a mutant promoter derived therefrom. Also provided herein are methods for producing a library of bacterial hemoglobin genes using a promoter ladder comprising a plurality of promoters derived from Corynebacterium glutamicum.
