    摘要: Using screening of transposon random insertion mutants, genes involved in a complex that is a three-component proton motive force-dependent multidrug efflux system were found to be involved in E. coli cell response to butanol. Reduced production of the AcrA and/or AcrB proteins of the complex confers increased butanol tolerance. E. coli strains with reduced AcrA or AcrB production and having a butanol or 2-butanone biosynthetic pathway are useful for production of butanol or 2-butanone.

    摘要: Using screening of transposon random insertion mutants, genes involved in accumulation of (p)ppGpp were found to be involved in bacterial cell response to butanol. Reduced production of proteins with enzymatic activity for (p)ppGpp biosynthesis confers increased butanol tolerance. Bacterial strains with reduced (p)ppGpp accumulation and having a butanol or 2-butanone biosynthetic pathway are useful for production of butanol or 2-butanone.

    摘要: The global effect on genes under different environmental conditions can be determined by a comprehensive gene expression profile. The present invention provides a method to monitor the changes in comprehensive cellular gene expression levels at single length resolution by using a high-density microarray prepared with a comprehensive collection of ORFs of a genome. Under different environmental conditions, directly and indirectly affected genes can be detected as the gene expression levels are induced or repressed in comparison to the control.

    摘要: Screening of fatty acid fed bacteria which are not natural butanol producers identified increased membrane cyclopropane fatty acid as providing improved butanol tolerance. Increasing expression of cyclopropane fatty acid synthase in the presence of the enzyme substrate that is either endogenous to the cell or fed to the cell, increased butanol tolerance. Bacterial strains with increased cyclopropane fatty acid synthase and having a butanol biosynthetic pathway are useful for production of butanol.
