  • 2011 (First Publication: 1 November 2011)
  • We previously showed that in Azotobacter vinelandii, accumulation of polyhydroxybutyrate (PHB) occurs mainly during the stationary phase, and that a mutation in phbR, encoding a transcriptionalContinue Reading

  • 2014 (First Publication: 1 March 2014)
  • In Azotobacter vinelandii, a cyst-forming bacterium, the alternative sigma factor RpoS is essential to the formation of cysts resistant to desiccation and to synthesis of the cyst-specific lipids,Continue Reading

  • 2008 (First Publication: 1 July 2008)
  • The industrially widely used polysaccharide alginate is a co-polymer of beta-D-mannuronic acid and alpha-L-guluronic acid (G), and the G residues originate from a polymer-level epimerization processContinue Reading
    The ptsP, ptsO, and ptsN genes encode Enzyme I(Ntr), NPr, and enzyme IIA(Ntr) (IIA(Ntr)) proteins of the nitrogen-related phosphotransferase system. These proteins participate in a phosphorylContinue Reading

  • Journal of bacteriology
  • 2006 (First Publication: 1 August 2006)
  • Alginate is a linear copolymer of beta-d-mannuronic acid and its C-5-epimer, alpha-l-guluronic acid. During biosynthesis, the polymer is first made as mannuronan, and various fractions of theContinue Reading

  • Journal of bacteriology
  • 2013 (First Publication: 15 April 2013)
  • Azotobacter vinelandii is a bacterium which undergoes a differentiation process leading to the formation of metabolically dormant cysts. During the encystment process, A. vinelandii producesContinue Reading

  • 2009 (First Publication: 1 May 2009)
  • During encystment of Azotobacter vinelandii, a family of alkylresorcinols (ARs) and alkylpyrones (APs) are synthesized. In the mature cyst, these lipids replace the membrane phospholipids and areContinue Reading
