Response of Nitrosospira sp. Stain AF-like ammonia oxidizers to changes in temperature, soil moisture content, and fertilizer concentration

Article Abstract:

The response of Nitrosospira sp. strain AF-like ammonia oxidizers to changing environmental conditions were studied by applying molecular methods and physiological measurements to Californian grassland soil manipulated in the laboratory. The observations suggests that Nitrosospira sp. strain AF-like bacteria might respond to increased temperature with an increase in activity, despite a decrease in abundance or the potential nitrification activity in such soils might be due to organisms other than bacteria.

Patterns of community change among ammonia oxidizers in meadow soils upon long-term incubation at different temperatures

Article Abstract:

Results demonstrate changes in the community structure of ammonia-oxidizing bacteria in both moist soil and soil slurry from the meadow as shown by amoA gene analysis. Two patterns of community change, that of different Neurospora clusters and of community shift within a single Nitrosospira cluster in KMS soil. Data suggest that temperature influences the ammonia oxidizer populations in the meadow soils.

Community composition and functioning of denitrifying bacteria from adjacent meadow and forest soils

Article Abstract:

Results suggest functional and structural community differences between the meadow and forest soils, such as nitrogen cycling processes and levels of denitrifying enzyme activity being higher in the meadow soils. Data indicate that the presence of many dominant and less-dominant denitrifying genotypes is characteristic of either of the communities.
