  • Patent number: 9447385
    Abstract: From a bacterial strain isolated from an environmental sample, after enrichment in medium containing 1-butanol as the carbon source, a new enzyme with butanol dehydrogenase activity was identified. The enzyme can convert butyraldehyde to 1-butanol, isobutyraldehyde to isobutanol, as well as 2-butanone to 2-butanol and thus is useful for biosynthesis of butanol in recombinant microbial hosts producing these substrates. The encoding gene, named sadB, was isolated from the strain identified as an isolate of Achromobacter xylosoxidans.

  • Patent number: 8795992
    Abstract: Increasing tolerance to butanol in yeast has been accomplished by increasing activity of the cell wall integrity pathway. Yeast with increased expression of SLT2p, a mitogen activated protein kinase of the MAPK module of the cell wall integrity pathway had increased tolerance to isobutanol. These yeast may be used for improved butanol production.

  • Patent number: 8557562
    Abstract: Increasing tolerance to butanol in yeast has been accomplished by increasing activity of the filamentous growth response. Yeast with increased expression of MSS11p, a transcriptional activator of the filamentous growth response pathway had increased tolerance to isobutanol. These yeast may be used for improved butanol production.

  • Publication number: 20120149080
    Abstract: High cell density cultures of yeast were found to have higher tolerance for butanol in the medium. The high cell density yeast cultures had greater survival and higher glucose utilization than cultures with low cell densities. Production of butanol using yeast in high cell density cultures is thus beneficial for improving butanol production.
