Community ecology of denitrifying bacteria in arable land [PDF]

, 2008
Denitrifying bacteria comprise a functional guild that under anaerobic conditions is able to use nitrogenous compound for respiration. Agricultural soils are often fertilized with nitrogen, and the reduction of nitrate and nitrite to nitric oxide ...

Soil pH: a key edaphic factor regulating distribution and functions of bacterial community along vertical soil profiles in red soil of pomelo orchard

BMC Microbiology, 2022
Background Soil microbes exist throughout the soil profile and those inhabiting topsoil (0–20 cm) are believed to play a key role in nutrients cycling. However, the majority of the soil microbiology studies have exclusively focused on the distribution of

Temperature-dependent changes in the soil bacterial community in limed and unlimed soil [PDF]

FEMS Microbiology Ecology, 2003
Abstract A humus soil with a pH(H(2)O) of 4.9 was limed to a pH of 7.5 and was incubated together with samples from unlimed and field limed (pH 6.1) soils at 5, 20 and 30 degrees C for up to 80 days. The changes in the phospholipid fatty acid (PLFA) pattern were most rapid for the bacterial community of the soil incubated at 30 degrees C, while no ...

A microbial community description of a heavy metal contaminated soil site [PDF]

, 2012
Tui mine area, with extremely low pH (2.9-3.3) values and high-metal concentrations, is one of the most contaminated sites in NZ. The structure of the microbial community in different soil layers (Top, Middle and Bottom) of the Tui mine tailing was ...

Variations in the physicochemical properties of soil, enzyme activities, and the characteristics of bacterial communities within algal biocrusts and subsoils across different plant communities

Global Ecology and Conservation
Algal biological soil crusts (ABSCs) as ecological engineers inhabiting the soil-atmosphere boundary in dryland. Bacteria living at this boundary drive the diversity of ecosystem functions and services. However, it is still unknown whether differences in

The Variation in the Rhizosphere Microbiome of Cotton with Soil Type, Genotype and Developmental Stage

Scientific Reports, 2017
Plant roots and soil microorganisms interact with each other mainly in the rhizosphere. Changes in the community structure of the rhizosphere microbiome are influenced by many factors.

Resolving Drivers of Microbial Community Structure in The Dry Valleys of Antarctica [PDF]

, 2014
Understanding the processes that underlie patterns of microbial distribution is fundamental to the field of microbial ecology, but extremely challenging given the complexity of natural systems.

Bacterial pH-optima for growth track soil pH, but are higher than expected at low pH

, 2011
One of the most influential factors determining the growth and composition of soil bacterial communities is pH. However, soil pH is often correlated with many other factors, including nutrient availability and plant community, and causality among factors

Relationship of Bacterial Microdiversity of Rhizosphere and Bulk Soil with Soil Organic Carbon Mineralization in Maize Fields

Shuitu baochi tongbao, 2023
[Objective] The bacterial community microdiversity in the maize rhizosphere and bulk soil was determined to study the relationship between microdiversity and soil organic carbon mineralization through the use of high-resolution taxonomy in order to ...

Effect of Soil Tillage Practices on Dynamic of Bacterial Communities in Soil

Agriculturae Conspectus Scientificus, 2016
Several studies have indicated that intensive tillage has notable effect on properties of the soil microbiota that may influence numerous important soils functions, e.g. mobilization of nutrients or change of the overall emission rates of greenhouse gases.
