Nitrogen fixation by symbiotic and free-living spirochetes.
Spirochetes from termite hindguts and freshwater sediments possessed homologs of a nitrogenase gene (nifH) and exhibited nitrogenase activity, a previously unrecognized metabolic capability in spirochetes. Fixation of 15-dinitrogen was demonstrated with termite gut Treponema ZAS-9 and free-living Spirochaeta aurantia. Homologs of nifH were also present in human oral and bovine ruminal treponeme...
متن کاملProperties of a novel extracellular cell-free ice nuclei from ice-nucleating Pseudomonas antarctica IN-74.
Some ice-nucleating bacterial strains, including Pantoea ananatis (Erwinia uredovora), Pseudomonas fluorescens, and Pseudomonas syringae isolates, were examined for the ability to shed ice nuclei into the growth medium. A novel ice-nucleating bacterium, Pseudomonas antarctica IN-74, was isolated from Ross Island, Antarctica. Cell-free ice nuclei from P. antarctica IN-74 were different from the ...
متن کاملTerminal organelle development in the cell wall-less bacterium Mycoplasma pneumoniae.
Mycoplasmas are cell wall-less bacteria considered among the smallest and simplest prokaryotes known, and yet several species including Mycoplasma pneumoniae have a remarkably complex cellular organization highlighted by the presence of a differentiated terminal organelle, a membrane-bound cell extension distinguished by an electron-dense core. Adhesin proteins localize specifically to the term...
متن کاملNumerical Simulation of Free Surface in the Case of Plane Turbulent Wall Jets in Shallow Tailwater
Wall-jet flow is an important flow field in hydraulic engineering, and its applications include flow from the bottom outlet of dams and sluice gates. In this paper, the plane turbulent wall jet in shallow tailwater is simulated by solving the Reynolds Averaged Navier-Stokes equations using the standard turbulence closure model. This study aims to explore the ability of a time splitting method ...
متن کاملVentricular free wall rupture.
BACKGROUND Left ventricular free wall rupture (FWR) is reported to occur in 2-6% of cases presenting with acute myocardial infarction. Mortality of this complication is very high, accounting for 20-30% of all infarct related deaths. The objective of our study was to present our surgical experience of free wall rupture over a period of five years from 2004-2009. METHODOLOGY A review of our rec...
