Available in PDF, EPUB and Kindle. Book excerpt: In the ten years since the publication of Modern Soil Microbiology, the study of soil microbiology has significantly changed, both in the understanding of the diversity and function of soil microbial communities and in research methods. Ideal for students in a variety of disciplines, this second edition provides a cutting-edge examination of a fascinating discipline that encompasses ecology, physiology, genetics, molecular biology, and biotechnology, and makes use of biochemical and biophysical approaches. The chapters cover topics ranging from the fundamental to the applied and describe the use of advanced methods that have provided a great thrust to the discipline of soil microbiology. Using the latest molecular analyses, they integrate principles of soil microbiology with novel insights into the physiology of soil microorganisms. The authors discuss the soil and rhizosphere as habitats for microorganisms, then go on to describe the different microbial groups, their adaptive responses, and their respective processes in interactive and functional terms. The book highlights a range of applied aspects of soil microbiology, including the nature of disease-suppressive soils, the use of biological control agents, biopesticides and bioremediation agents, and the need for correct statistics and experimentation in the analyses of the data obtained from soil systems.
Download or read book Diverse Microbial Carbon as a Source of Soil Organic Matter written by Heather Mae Throckmorton and published by . This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Soil microorganisms are known to contribute a substantial amount of C to soil, but little is known of the importance of microbial biochemistry as a factor influencing soil organic matter (SOM) dynamics, or mechanisms controlling the stability of diverse microbial C in soil. This research assessed the potential for stabilization of microbial cells and extracellular products (EPS) in two contrasting forest ecosystems. While there were some differences in the chemical composition of diverse microbial cell isolates and EPS, both across groups and for microbes of the same group but isolated from different origins, microbial cells exhibited similar turnover rates in soils; and any differences that were observed did not correlate with measured chemical properties of microbial cells as determined by elemental analyses (C and N) or Py-GC-MS. Results suggest that, unlike plant residues, the source and quality of microbial C does not substantially influence its stability in soil. Chemical characterization showed some differences between four biochemically diverse microbial groups from California and Puerto Rico and their native soils; but greater similarities. Results suggest that microbial cells and products accumulate in soils and contribute substantially to the overall soil organic matter (SOM) signature. Additionally, results showed that diverse microbial groups and EPS exhibit similar chemical complexity as SOM, suggesting that the production of microbial biomass and turnover does not reduce the biochemical complexity of SOM as previously hypothesized. Site specific effects for input microbial residues were observed in both whole soils and soil fractions, suggesting different mechanisms operate at each site to influence the turnover of specific microbial C. Site differences likely occurred due to different native soil microbial communities, which likely differ in enzymatic expression patterns or substrate utilization preferences. However, numerous edaphic and climatic factors differ between sites, and the effects of specific factors controlling the turnover of microbial isolates are difficult to fully differentiate. Site differences in C cycling were further highlighted by chemical characterization of soils, which showed unique compounds and distinct SOM signatures for California and Puerto Rico soils. Differences in the chemical composition of native SOM at both sites support different processes and mechanism controlling soil C. Substantial climatic differences between the two study sites resulted in greater overall decomposition rates in PR than CA, as expected. The abundance of decomposition byproducts suggest that primary litter inputs likely have little effect on the overall chemical of SOM; rather, decomposition products (the chemistry and total amount of stabilized vs. unstabilized C) likely have a greater influence on the overall SOM composition. These results were supported by characterization of soil C fractions, which showed greater differences in the composition of mineral- associated SOM than for SOM less associated with soil minerals. Results suggest that the distinct microbial communities at the two study sites correspond to unique biogeochemical processes which result in different types of compounds available to stabilize with soil minerals. At both sites, association with soil minerals through direct complexation or intra-aggregate occlusion increased the stability of microbial C. Microbial C turnover in operationally defined soil physical fractions support different mechanisms controlling the turnover of microbial C at the two study sites. In particular, results suggest microbial C with lesser association with soil minerals was more susceptible to effects by climate; as differences in the overall turnover of microbial C were more pronounced in the FLF and OLF in California soil fractions. The pronounced effect of microbial residue quality in CA, with lower associations with the mineral matrix (i.e. the FLF and OLF), suggests that these fractions may be sensitive indicators of microbial residue decomposability in addition to plant litter decomposability as previously hypothesized. However, the usefulness of these fractions for predicting litter quality inputs may be sight-specific. For example, our results showed that in CA, uncomplexed microbial C showed a greater sensitivity to any effect of inherent recalcitrance of microbial inputs, whereas in PR this effect did not occur. Greater stability of microbial C in aggregate-occluded fractions in CA than in PR also supports different mechanisms operating at each site, likely associated with the dominating fungal community in CA which could have redistributed the input 13C into aggregates. Mineral-complexed microbial C was relatively stable in PR, where the native microbial community is dominated by bacteria, which typically reside in water films on mineral surfaces. Results suggest that, in addition to potential differences in enzyme expression patterns or unique substrate preferences and discrimination across sites influencing the stability of diverse microbial C residues applied to soils, the physiology of the native living microbial communities likely played an important role in the uptake and redistribution of input microbial 13C in different SOM fractions. This research highlights important interactions of factors operating at different scales to affect C turnover from diverse microbial groups and stabilization and chemistry of native SOM, and associated stabilization mechanisms. Moreover, the effect of microbial residue quality on its turnover was dependent on site, as well as its location in the mineral matrix and relative interaction with soil minerals. Additionally, the interaction of microbial residue quality and mineral association on microbial C stabilization differed between the two sites, with results showing greater overall discrimination in PR, but suggest that in CA relative association (or lack-thereof) with mineral matrix had a greater influence on the retention of diverse microbial residues. Our results suggest that unique effects across sites controlling differences in the stabilities of specific microbial C inputs, and associated stabilization mechanisms, may be as important as macromolecular structure and recalcitrance.
Download or read book Microbial Communities written by Heribert Insam and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 273 pages. Available in PDF, EPUB and Kindle. Book excerpt: Research on decomposer communities of terrestrial ecosystems for a long time has focussed on microbial biomass and gross turnover parameters. Recently, more and more attempts are made to look beyond the biomass, and more specifically determine functions and populations on a smaller scale-in time and space. A multitude of techniques is being improved and developed. Garland and Mills (1991) triggered a series of publications on substrate utilization tests in the field of microbial ecology. Despite several promising results for different applications in different laboratories, many problems concerning the assay and the interpretation of results became evident. After individual discussions on the approach with colleagues from various laboratories we started to plan a workshop on the matter. The response on our first circular was extraordinary, and instead of a small workshop it became a meeting with almost 150 participants. The meeting was named 'Substrate use for characterization of microbial communities in terrestrial ecosystems' (SUBMECO) and was held in Innsbruck, Austria, from Oct. 16-18, 1996. The very focussed scope attracted enthusiastic advocates of the approach, and also serious critics. Some of the topics concerned improvements of current inoculation and incubation techniques, ranging from sample pre-treatment, inoculum density and incubation temperature to statistical data handling. New methods for calculating microbial diversity were proposed, as well as bootstrap methods that allow statistics with many variables on a relatively low number of replicates.
