Temporal variations of oxygen consumption, sensitivity to metal spiking, and microbial diversity were investigated during a one-year survey at the sediment-water interface in the tropical lagoon of New Caledonia. Sediment oxygen consumption...
Establishment and early succession of a multispecies biofilm composed of soil bacteria [0.03%]
土壤细菌多物种菌胶团的建立及早期演替

Guanabara Bay is an eutrophic estuarine system located in a humid tropical region surrounded by the second largest metropolitan area of Brazil. This study explores the contrasting environmental chemistry and microbiological parameters that ...
Improvements of polymerase chain reaction and capillary electrophoresis single-strand conformation polymorphism methods in microbial ecology: toward a high-throughput method for microbial diversity studies in soil [0.03%]
微生物生态学中PCR和毛细管电泳单链构象多态性方法的改进：迈向土壤微生物多样性研究的高通量方法
Lucie Zinger,Jérôme Gury,Frédéric Giraud et al.
Lucie Zinger et al.
The molecular signature of bacteria from soil ecosystems is an important tool for studying microbial ecology and biogeography. However, a high-throughput technology is needed for such studies. In this article, we tested the suitability of a...

Pau Maduell et al.
The ability of several Bacillus thuringiensis strains to colonize plant surfaces was assessed and compared with that of more common epiphytic bacteria. While all B. thuringiensis strains multiplied to some extent after inoculation on bean p...
Mesophilic Actinomycetes in the natural and reconstructed sand dune vegetation zones of Fraser Island, Australia [0.03%]

D I Kurtböke
The natural coastal habitat of Fraser Island located in the State of Queensland, Australia, has been disturbed in the past for mining of the mineral sand ilmenite. Currently, there is no information available on whether these past mining di...
Ecological occurrence of Gluconacetobacter diazotrophicus and nitrogen-fixing Acetobacteraceae members: their possible role in plant growth promotion [0.03%]
Gluconacetobacter diazotrophicus及固氮醋酸菌属的生态分布及其促生作用的可能性
V S Saravanan,M Madhaiyan,Jabez Osborne et al.
V S Saravanan et al.
Gluconacetobacter diazotrophicus has a long-standing history of bacterial-plant interrelationship as a symbiotic endophyte capable of fixing atmospheric nitrogen. In low nitrogen fertilized sugarcane fields it plays a significant role and i...
Changes in morphology and elemental composition of Vibrio splendidus along a gradient from carbon-limited to phosphate-limited growth [0.03%]
沿碳限制至磷限制生长梯度发光 Vibrio splendidus 的形态和元素组成的改变
Trond Løvdal,Evy F Skjoldal,Mikal Heldal et al.
Trond Løvdal et al.
We examined morphology, elemental composition (C, N, P), and orthophosphate-uptake efficiency in the marine heterotrophic bacterium Vibrio splendidus grown in continuous cultures. Eight chemostats were arranged along a gradient of increasin...
Impact of ectomycorrhizosphere on the functional diversity of soil bacterial and fungal communities from a forest stand in relation to nutrient mobilization processes [0.03%]
外菌根土壌细菌和真菌群落功能多样性与养分转化过程之间的关系研究——以小黑山林场森林生态系统为例
Christophe Calvaruso,Marie-Pierre Turpault,Elisabeth Leclerc et al.
Christophe Calvaruso et al.
The ectomycorrhizal symbiosis alters the physicochemical and biological conditions in the surrounding soil, thus creating a particular environment called ectomycorrhizosphere, which selects microbial communities suspected to play a role in ...
Genetic diversity of plankton community as depicted by PCR-DGGE fingerprinting and its relation to morphological composition and environmental factors in Lake Donghu [0.03%]
长江中游东湖浮游生物群落遗传多样性及其与形态多样性和环境因子的关系
