Dynamics of microbial community composition and soil organic carbon mineralization in soil following addition of pyrogenic and fresh organic matter
ISME Journal - Tập 10 Số 12 - Trang 2918-2930 - 2016
Thea Whitman, Charles Pepe‐Ranney, Akio Enders, Chantal Koechli, Ashley Campbell, Daniel H. Buckley, Johannes Lehmann
Abstract Pyrogenic organic matter (PyOM) additions to soils can have large impacts on soil organic carbon (SOC) cycling. As the soil microbial community drives SOC fluxes, understanding how PyOM additions affect soil microbes is essential to understanding how PyOM affects SOC. We studied SOC dynamics and surveyed soil bacterial communities after OM additions in a field experiment. We produced and ... hiện toàn bộ
Novel phosphate-solubilizing bacteria enhance soil phosphorus cycling following ecological restoration of land degraded by mining
ISME Journal - Tập 14 Số 6 - Trang 1600-1613 - 2020
Jie‐Liang Liang, Jun Liu, Pu Jia, Taotao Yang, Qingwei Zeng, Sheng‐chang Zhang, Bin Liao, Wensheng Shu, Jintian Li
Abstract Little is known about the changes in soil microbial phosphorus (P) cycling potential during terrestrial ecosystem management and restoration, although much research aims to enhance soil P cycling. Here, we used metagenomic sequencing to analyse 18 soil microbial communities at a P-deficient degraded mine site in southern China where ecological restoration was implemented using two soil am... hiện toàn bộ
Taxonomical and functional microbial community selection in soybean rhizosphere
ISME Journal - Tập 8 Số 8 - Trang 1577-1587 - 2014
Lucas William Mendes, Eiko E. Kuramae, Acácio Aparecido Navarrete, Johannes A. van Veen, Siu Mui Tsai
AbstractThis study addressed the selection of the rhizospheric microbial community from the bulk soil reservoir under agricultural management of soybean in Amazon forest soils. We used a shotgun metagenomics approach to investigate the taxonomic and functional diversities of microbial communities in the bulk soil and in the rhizosphere of soybean plants and tested the validity of neutral and niche... hiện toàn bộ
Differences in soil bacterial diversity: driven by contemporary disturbances or historical contingencies?
ISME Journal - Tập 2 Số 3 - Trang 254-264 - 2008
Yuan Ge, Ji‐Zheng He, Yong‐Guan Zhu, Jiabao Zhang, Zhihong Xu, Limei Zhang, Yuan‐Ming Zheng
Abstract Contemporary environmental disturbances and historical contingencies are considered to be major factors driving current differences in microbial diversity. However, little was known about their relative importance. This study combines culture-independent molecular techniques and advanced statistical analyses to examine quantitatively the relative importance of contemporary disturbances an... hiện toàn bộ
Effects of environmental variation and spatial distance on Bacteria, Archaea and viruses in sub-polar and arctic waters
ISME Journal - Tập 7 Số 8 - Trang 1507-1518 - 2013
Christian Winter, Blake Matthews, Curtis A. Suttle
Abstract We investigated the influence of environmental parameters and spatial distance on bacterial, archaeal and viral community composition from 13 sites along a 3200-km long voyage from Halifax to Kugluktuk (Canada) through the Labrador Sea, Baffin Bay and the Arctic Archipelago. Variation partitioning was used to disentangle the effects of environmental parameters, spatial distance and spatia... hiện toàn bộ
Patterns and processes in microbial biogeography: do molecules and morphologies give the same answers?
ISME Journal - Tập 10 Số 7 - Trang 1779-1790 - 2016
Luciana F. Santoferrara, Jean‐David Grattepanche, Laura A. Katz, George B. McManus
Abstract Our knowledge on microbial biogeography depends on the way we define and study diversity. In contrast to most microbes, some protist lineages have conspicuous structures that allow comparisons of diversity concepts and measures—those based on molecules and those based on morphology. We analyzed a group of shell-bearing planktonic ciliates, the tintinnids, in a coast-to-ocean gradient usin... hiện toàn bộ
Microbial contributions to climate change through carbon cycle feedbacks
ISME Journal - Tập 2 Số 8 - Trang 805-814 - 2008
Richard D. Bardgett, Chris Freeman, Nick Ostle
Abstract There is considerable interest in understanding the biological mechanisms that regulate carbon exchanges between the land and atmosphere, and how these exchanges respond to climate change. An understanding of soil microbial ecology is central to our ability to assess terrestrial carbon cycle–climate feedbacks, but the complexity of the soil microbial community and the many ways that it ca... hiện toàn bộ
Lactobacillus-dominated cervicovaginal microbiota associated with reduced HIV/STI prevalence and genital HIV viral load in African women
ISME Journal - Tập 8 Số 9 - Trang 1781-1793 - 2014
Hanneke Borgdorff, Evgeni Tsivtsivadze, Rita Verhelst, Massimo Marzorati, Suzanne Jurriaans, Gilles Ndayisaba, Frank Schuren, Janneke van de Wijgert
Abstract Cervicovaginal microbiota not dominated by lactobacilli may facilitate transmission of HIV and other sexually transmitted infections (STIs), as well as miscarriages, preterm births and sepsis in pregnant women. However, little is known about the exact nature of the microbiological changes that cause these adverse outcomes. In this study, cervical samples of 174 Rwandan female sex workers ... hiện toàn bộ
Impact of diet and individual variation on intestinal microbiota composition and fermentation products in obese men
ISME Journal - Tập 8 Số 11 - Trang 2218-2230 - 2014
Anne Salonen, Leo Lahti, Jarkko Salojärvi, Grietje Holtrop, Katri Korpela, Sylvia H. Duncan, Priya Date, Freda Farquharson, Alexandra M. Johnstone, G. E. Lobley, Petra Louis, Harry J. Flint, Willem M. de Vos
Abstract There is growing interest in understanding how diet affects the intestinal microbiota, including its possible associations with systemic diseases such as metabolic syndrome. Here we report a comprehensive and deep microbiota analysis of 14 obese males consuming fully controlled diets supplemented with resistant starch (RS) or non-starch polysaccharides (NSPs) and a weight-loss (WL) diet. ... hiện toàn bộ
The networks of human gut microbe–metabolite associations are different between health and irritable bowel syndrome
ISME Journal - Tập 9 Số 8 - Trang 1899-1903 - 2015
Vijay Shankar, Daniel Homer, Laura Rigsbee, Harry J. Khamis, Sonia Michail, Michael L. Raymer, Nicholas V. Reo, Oleg Paliy
Abstract The goal of this study was to determine if fecal metabolite and microbiota profiles can serve as biomarkers of human intestinal diseases, and to uncover possible gut microbe–metabolite associations. We employed proton nuclear magnetic resonance to measure fecal metabolites of healthy children and those diagnosed with diarrhea-predominant irritable bowel syndrome (IBS-D). Metabolite levels... hiện toàn bộ
