Succession of bacterial populations during plant residue decomposition in rice field soil.
The incorporation of rice residues into paddy fields strongly enhances methane production and emissions. Although the decomposition processes of plant residues in rice field soil has been documented, the structure and dynamics of the microbial communities involved are poorly understood. The purpose of the present study was to determine the dynamics of short-chain fatty acids and the structure o...
متن کاملBacterial Community Succession in Pine-Wood Decomposition
Though bacteria and fungi are common inhabitants of decaying wood, little is known about the relationship between bacterial and fungal community dynamics during natural wood decay. Based on previous studies involving inoculated wood blocks, strong fungal selection on bacteria abundance and community composition was expected to occur during natural wood decay. Here, we focused on bacterial and f...
متن کاملSoil bacterial community succession during long-term ecosystem development.
The physicochemical and biological gradients of soil and vegetative succession along the Franz Josef chrono sequence in New Zealand were used to test whether bacterial communities show patterns of change associated with long-term ecosystem development. Pyrosequencing was conducted on soil-derived 16S rRNA genes at nine stages of ecosystem progression and retrogression, ranging in age from 60 to...
متن کاملIsotopic ((13)C) fractionation during plant residue decomposition and its implications for soil organic matter studies.
Carbon isotopic fractionations in plant materials and those occurring during decomposition have direct implications in studies of short-and longer-term soil organic matter dynamics. Thus the products of decomposition, the evolved CO(2) and the newly formed soil organic matter, may vary in their (13)C signature from that of the original plant material. To evaluate the importance of such fraction...
متن کاملEffects of Plant Residue Extract and Cobalamin on Growth and Propionate Production of Propionicimonas paludicola Isolated from Plant Residue in Irrigated Rice Field Soil
Since most of the anaerobic bacterial isolates from rice plant residue in irrigated rice field soil grew slowly or weakly in the medium (PY medium) used, growth factors for the isolates were investigated. Plant residue extract (RE) was prepared by autoclaving plant residue collected from the soil, and RE was added to the medium as a possible source of growth factors. With the addition, growth o...
