The unphosphorylated EIIA(Ntr) protein represses the synthesis of alkylresorcinols in Azotobacter vinelandii. [PDF]
Upon encystment induction, Azotobacter vinelandii produces the phenolic lipids alkylresorcinols (ARs) that are structural components of the cysts. The enzymes responsible for the ARs synthesis are encoded in the arsABCD operon, whose expression is ...

Improving the Efficiency of a Bioreactor Equipped With Mixed‐Flow Impellers
The present work investigated the biological performance of mixed‐flow impellers. To the authors’ knowledge, this is the first experimental study on such impellers in a fermentation process using A. vinelandii, which was chosen as a microorganism due to its high oxygen demand.

Effect of pH on growth and nitrogen fixation of Azotobacter Spp. [PDF]
Three species o f Azotobacter were isolated from prawn-cum-paddy fields o f Kerala. These strains were found to have the optimum pH for growth and nitrogen fixation near or slightly above neutrality, i.e., in the pH range o f 7.0 to 8.

Identification of sulfurtransferase enzymes in Azotobacter vinelandii [PDF]
Rhodanese and 3‐mercaptopyruvate sulphurtransferase have been identified in A. vinelandii. Two distinct active fractions of the two sulphurtransferases were obtained after FPLC ion‐exchange chromatography of material partially purified from crude extracts. Rhodanese has been purified to homogeneity, and it consists of one polypeptide chain of M r ca 25

Metal‐Based Materials for CO2 Conversion in MES and PBS Systems
Metal‐based materials bridge abiotic and biological systems, enabling efficient CO2‐to‐chemical conversion via enhanced electron transfer in microbial electrosynthesis and photocatalytic biohybrid systems. ABSTRACT Metal‐based materials—including pure metals, alloys, compounds, and MOFs—play pivotal roles in microbial electrosynthesis (MES) and ...

Turnover-Dependent Inactivation of the Nitrogenase MoFe-Protein at High pH [PDF]
Proton uptake accompanies the reduction of all known substrates by nitrogenase. As a consequence, a higher pH should limit the availability of protons as a substrate essential for turnover, thereby increasing the proportion of more highly reduced forms ...

Structure of the Azotobacter vinelandii surface layer [PDF]
Electron microscopy of the Azotobacter vinelandii tetragonal surface array, negatively stained with ammonium molybdate in the presence of 1 mM calcium chloride, showed an apparent repeat frequency of 12 to 13 nm. Image processing showed dominant tetrad units alternating with low-contrast cruciform structures formed at the junction of slender linkers ...
