Nitrospira bacteria in paddy soil reduced by biochar application [PDF]
AbstractBiochar application can depress nitrification in paddy soils, but the microbiological mechanisms involved in this process are not clearly understood. This study was conducted to test the hypothesis that biochar may affect nitrification bacteria in paddy soils.

Application of COMPOCHIP Microarray to Investigate the Bacterial Communities of Different Composts [PDF]
A microarray spotted with 369 different 16S rRNA gene probes specific to microorganisms involved in the degradation process of organic waste during composting was developed. The microarray was tested with pure cultures, and of the 30,258 individual probe-

Niche specialization of comammox Nitrospira in terrestrial ecosystems: Oligotrophic or copiotrophic?
The discovery of complete ammonia oxidizers, comammox Nitrospira, represents a breakthrough in the history of nitrification research. Nitrospira inopinata, which was obtained from an aquatic ecosystem, is the only pure comammox bacterial isolate reported

Due to global change, increasing nutrient input to ecosystems dramatically affects the nitrogen cycle, especially the nitrification process. Nitrifiers including ammonia-oxidizing archaea (AOAs), ammonia-oxidizing bacteria (AOBs), nitrite-oxidizing bacteria (NOBs), and recently discovered complete ammonia oxidizers (comammoxs) perform nitrification ...

Metagenomic analysis of rapid gravity sand filter microbial communities suggests novel physiology of Nitrospira spp [PDF]
Rapid gravity sand filtration is a drinking water production technology widely used around the world. Microbially catalyzed processes dominate the oxidative transformation of ammonia, reduced manganese and iron, methane and hydrogen sulfide, which may ...

Nitrification is the two-step aerobic oxidation of ammonia to nitrate via nitrite in the nitrogen-cycle on earth. However, very limited information is available on how fertilizer regimes affect the distribution of nitrite oxidizers, which are involved in

Effect of the dilution rate on microbial competition: r-strategist can win over k-strategist at low substrate concentration. [PDF]
The conditions present in both in vitro and in vivo ecosystems determine the microbial population harbouring it. One commonly accepted theory is that a species with a high substrate affinity and low growth rate (k-strategist) will win the competition ...
