Production of aromatic compounds during methanogenic degradation of straw in rice field soil.
Production of CH(4) in anoxic rice field soil is stimulated by the addition of rice straw. Previous experiments showed that acetate and propionate are the most important intermediates of the carbon flow to CH(4), and accumulate if CH(4) production is inhibited by 2-bromoethanesulfonate (BES). However, some unidentified compounds were found to accumulate in addition. We now identified them as be...
متن کاملMethanogenic degradation of lignin-derived monoaromatic compounds by microbial enrichments from rice paddy field soil
Anaerobic degradation of lignin-derived aromatics is an important metabolism for carbon and nutrient cycles in soil environments. Although there are some studies on degradation of lignin-derived aromatics by nitrate- and sulfate-reducing bacteria, knowledge on their degradation under methanogenic conditions are quite limited. In this study, methanogenic microbial communities were enriched from ...
متن کاملMethyl Fluoride Affects Methanogenesis Rather than Community Composition of Methanogenic Archaea in a Rice Field Soil
The metabolic pathways of methane formation vary with environmental conditions, but whether this can also be linked to changes in the active archaeal community structure remains uncertain. Here, we show that the suppression of aceticlastic methanogenesis by methyl fluoride (CH(3)F) caused surprisingly little differences in community composition of active methanogenic archaea from a rice field s...
متن کاملSyntrophic associations in methanogenic degradation.
For many decades, microbiology has tried to understand the activities of microorganisms in nature on the basis of pure culture studies which allow reliable identification of the actors in play and reproducible assessments of their activities under defined conditions. This approach has undoubtedly been successful, but it has overlooked that microbes in nature interact with each other and may dep...
متن کاملEnergetics of syntrophic cooperation in methanogenic degradation.
Fatty acids and alcohols are key intermediates in the methanogenic degradation of organic matter, e.g., in anaerobic sewage sludge digestors or freshwater lake sediments. They are produced by classical fermenting bacteria for disposal of electrons derived in simultaneous substrate oxidations. Methanogenic bacteria can degrade primarily only one-carbon compounds. Therefore, acetate, propionate, ...
