TL;DR: In this article, the influence of the separation of cells from Fe(III)-oxides (125-63 μm) was studied in model experiments using iron-reducing bacteria (Clostridium butyricum S 22 a and Bacillus polymyxa S 55) which lower the Eh considerably.

TL;DR: In this paper, model experiments on the mechanism of bacterial iron-reduction in water-logged soils were conducted to investigate the influence of NO, (KNO), and/or Mn02-Powder (Merck) on Fe(I1) formation and rH (calculated from pH and Eh) was measured.

TL;DR: The effect of increasing amounts of nitrogen (nitrate or urea) on the nitrogen fixing capacity (acetylene reduction assay = ARA), growth (fresh and dry weight) and the number of stem and root-nodules of the tropical legume Aeschynomene afraspera was studied in hydroponic cultures (in growth cabinet) as well as in pot experiments (field conditions) as discussed by the authors.

TL;DR: In this paper, the authors present a model for the Kohlenstoffmineralisation (CO2-Freisetzung) and denitrifikation (quantitativ und qualitative) of drei verschiedenen Bakterien (Aeromonas “denitrificans” S224, Azospirillum lipoferum DSM 1843 and Bacillus licheniformis ATCC 14580) in vier unterschiedlichen Boden (Allochthone Vega, Par

TL;DR: In this article, the authors investigated the effect of high nitrate application on the kinetic and gaseous composition of denitrification in 16 soil horizons after application of a relatively high amount of nitrate (400 μg NO N/g dry soil) at defined conditions (He atmosphere; 80 % WHC; 30°C; 3 weeks).
