Propachlor degradation by a soil bacterial community [PDF]

Applied and Environmental Microbiology, 1991
Soil from a pesticide disposal site was used to enrich for microorganisms that degraded the acylanilide herbicide propachlor (2-chloro-N-isopropylacetanilide). After seven transfers of the enrichment, the culture contained about six strains. The highest yield of microbial biomass occurred if just two of these isolates, strains DAK3 and MAB2, were ...

Effects of warming and nitrogen addition on soil fungal and bacterial community structures in a temperate meadow

Frontiers in Microbiology, 2023
Soil microbial communities have been influenced by global changes, which might negatively regulate aboveground communities and affect nutrient resource cycling.

Soil salinity is the main factor influencing the soil bacterial community assembly process under long-term drip irrigation in Xinjiang, China

Frontiers in Microbiology, 2023
Identifying the potential factors associated with the impact of long-term drip irrigation (DI) on soil ecosystems is essential for responding to the environmental changes induced by extensive application of DI technology in arid regions.

Elevational characteristics of soil bacterial community and their responses to soil translocation at a mountainside in northwest Sichuan, China

Scientific Reports, 2023
How the soil bacterial communities vary with elevation is context-dependent, and the effect of soil translocation between elevations on bacterial community structure and metabolic function was not fully understood yet.

Drip irrigation shapes the soil bacterial communities and enhances jujube yield by regulating the soil moisture content and nutrient levels

Agricultural Water Management, 2023
In the agricultural zones of the arid Xinjiang region of China, reducing irrigation is mandatory. However, irrigation affects the composition and diversity of the soil bacterial community which is vital to crop yield.

Plant chemical variation mediates soil bacterial community composition

Scientific Reports, 2023
AbstractAn important challenge in the study of ecosystem function is resolving how plant antiherbivore chemical defence expression may influence plant-associated microbes, and nutrient release. We report on a factorial experiment that explores a mechanism underlying this interplay using individuals of the perennial plant Tansy that vary genotypically ...

Canopy and Understory Nitrogen Addition Alters Organic Soil Bacterial Communities but Not Fungal Communities in a Temperate Forest

Frontiers in Microbiology, 2022
Atmospheric nitrogen (N) deposition is known to alter soil microbial communities, but how canopy and understory N addition affects soil bacterial and fungal communities in different soil layers remains poorly understood.

Effects of Urban–Rural Environmental Gradient on Soil Microbial Community in Rapidly Urbanizing Area

Ecosystem Health and Sustainability, 2023
Rapid urbanization considerably changes the urban–rural landscape, soil environment, and soil ecosystem functions. Within terrestrial ecosystems, microorganisms play key roles in soil ecosystem functions and are highly vulnerable to the effects of rapid ...

The diversity and biogeography of soil bacterial communities [PDF]

Proceedings of the National Academy of Sciences, 2006
For centuries, biologists have studied patterns of plant and animal diversity at continental scales. Until recently, similar studies were impossible for microorganisms, arguably the most diverse and abundant group of organisms on Earth.
