- 3 February 1993
NATURAL oxidation of ferrous to ferric iron by bacteria such as Thiobacillus ferrooxidans or Gallionella ferruginea1, or by chemical oxidation2,3 has previously been thought always to involve… Expand
Mechanistic analysis of ammonium inhibition of atmospheric methane consumption in forest soils.
Nitrite, the end product of methanotrophic ammonia oxidation, was a more effective inhibitor of methane consumption than ammonium, and factors that stimulated ammonium oxidation in soil enhanced ammonium inhibition of methane oxidation, probably as a result of enhanced nitrite production. Expand
Microbiology of flooded rice paddies.
This review presents the current knowledge about the highly complex microbiology of flooded rice paddies and describes the predominant microbial groups and their function with particular regard to bacterial populations utilizing polysaccharides and simple sugars, and to the methanogenic archaea.

Effect of increasing atmospheric methane concentration on ammonium inhibition of soil methane consumption
SOILS currently consume about 30–40 Tg methane per year1,2, which is comparable to the net annual increase in atmospheric methane concentration from 1980 to 19903. Most soils consume methane2,4–9,… Expand
Anaerobic degradation of aniline and dihydroxybenzenes by newly isolated sulfate-reducing bacteria and description of Desulfobacterium anilini
A new, rod-shaped, Gram-negative, non-sporing sulfate reducer (strain Ani1) was enriched and isolated from marine sediment with aniline as sole electron donor and carbon source. The strain degraded… Expand
Stability of methane oxidation capacity to variations in methane and nutrient concentrations
Methane uptake by soil was rapidly inhibited by the addition of antibacterial antibiotics as well as by the eukaryotic antibiotic, cycloheximide, and methane consuuption by soil incubated under the same conditions was temporally stable. Expand
Ammonium and Nitrite Inhibition of Methane Oxidation by Methylobacter albus BG8 and Methylosinus trichosporium OB3b at Low Methane Concentrations.
The results of this study provide new insights that explain some of the previously observed interactions among ammonium, nitrite, methane, and methane oxidation in soils and aquatic systems. Expand
Simultaneous Determination of Iron ( III ) , Iron ( II ) , and Manganese ( II ) in Environmental Samples by Ion Chromatography
A chromatographic method was developed for simultaneous determination of Fe(III), Fe(II), Mn(II), and other transition metals. A high-performance polymer-coated silica-based cation exchange column… Expand

Cultivation-independent retrieval of 16S rRNA gene sequences revealed that rice roots are also colonized by various members of this novel subgroup, allowing the assumption that these organisms are physiologically adapted to environments characterized by spatial and temporal fluctuations between oxic and anoxic conditions, as is typically the case for flooded rice soil.
